[EMAIL PROTECTED] changed: What|Removed |Added Component|pdf renderer|general OS/Version|Windows NT/2K |All Platform|PC |All Version|0.20.5 |all --- Additional Comments From [EMAIL PROTECTED] 2004-01-18 07:50 --- As I've been occupying myself with row- and column-span in HEAD lately (1.0dev), just want to add the following: The added example fo-file specifies background-colors on the row. If I interpret the spec correctly the background being overpainted is actually compliant. A spanned cell *can* have a different background in each of the table-grid-units it occupies. Defining BGC on the row is one way of contributing in this effect. WRT the content and the borders, this is of course a different matter... (Borders -are- working, they're just overpainted) I guess it has something to do with the sequential processing of the table-rows, where, in case of RowSpan, a number of rows should be processed as a unity. I doubt that the issue will be fixed in 0.20.5, but it will certainly be addressed in 1.0dev. Thanks for bringing this back to our attention!

What if default xml=fred.xml is mapped to xml=file://./fred.xml where the servlet's 'working dir' is defined relative to servlet context.

Comments on new property maker implementation
Finn, I've looked at your changes--I like them, and I'm thankful to have someone on our team to be able to redesign the properties as you have. Getting rid of the 250 autogenerated or so classes will be a welcome improvement. Comments right now: 1.) Unlike what I was saying earlier, I don't think we should move from Property.Maker to a new PropertyMaker class after all, your design looks fine. I've noticed most subclasses of Property.Maker are within subclasses of Properties themselves (e.g., LengthProperty, LengthProperty.Maker, etc.) so it looks like a neat, clean design. 2.) The new FOPropertyMapping.java class appears (1) autogenerated, and (2) to be an XSLT masterpiece at that as well. If it is indeed in good shape, I'd like you to submit it to Bugzilla as the new fo-property-mapping.xsl, replacing the old one of that name in src/codegen. (We won't apply it however, until we no longer need the current autogenerated fo-property-mapping.xsl, i.e., until all the old properties have been tossed out.) This way if we have to make wide-ranging changes to FOPropertyMapping, we'll have a XSLT source file we can conveniently work with. (Note that putting it in codegen does *not* mean that it will be automatically autogenerated anymore--it won't, just as constants.xsl no longer is--we'll pull it out of the main Ant build target at that time and keep it the separate, manual xsltToJava target in our build file[1]. [1] http://cvs.apache.org/viewcvs.cgi/xml-fop/build.xml?rev=1.97view=auto ) Comments on FOPropertyMapping: I like removing all these autogenerated classes, but I think we can still keep some processing at compile-time for more of a performance gain, as follows: 3) I think the runtime construction of the generic properties (genericColor, genericCondBorderWidth, etc.) may not be necessary. We can still have those xslt-generated into classes (6-8 classes total), but this time we check them into FOP (again, keeping the xsl available for manual re-generation when needed). But most of the generic classes are so small (your initialization of GenericCondPadding is only 4 lines of code), that going back to creating concrete classes would be noticeably beneficial either, so I'm not recommending this change. One thing that *does* stick out, however, is the 100 or so addKeyword() calls for genericColor (the largest of the generic properties): genericColor.addKeyword(antiquewhite, #faebd7); genericColor.addKeyword(aqua, #00); genericColor.addKeyword(aquamarine, #7fffd4); . I'd like us to have a static array of these values--i.e., something done compile-time, that genericColor can just reference, so we don't have to do this keyword initialization. 4) I'd also like us to, rather than call setInherited() and setDefault() for each of the properties during initialization, for the Property/Property.Maker classes to just reference that information from two (new) static arrays, added to Constants.java. We can also get rid of these two setter methods as well (ideally there shouldn't be setters for these attributes anyway--they should remain inherent to the Property.) This change will allow us to take advantage of the fact that we are now on int-constants. getDefault(PR_WHATEVER), for example, is just Constants.DefaultArray[PR_WHATEVER]. 5) Similar to (b) above, several of the makers also have a useGeneric() initialization requirement: m = new CondLengthProperty.Maker(PR_PADDING_END); m.useGeneric(genericCondPadding); For those Makers that require it, I'd like the constructor to be expanded to this: m = new CondLengthProperty.Maker(PR_PADDING_END, genericCondPadding); Again, getting rid of the useGeneric() function. This is for more speed, encapsulation, and also shrinking FOPropertyMapping class a bit. Sorry for the long post. I'll probably have other comments in other areas, but this is all I've studied for now. Thoughts? Thanks, Glen __ Do you Yahoo!? Yahoo!

Re: [PATCH] abandoning code-generated Property.Maker
Team, I moved the 64 or so property value interfaces from separate autogenerated files to Constants.java yesterday. The work is not perfect--there are still a few linkages to (autogenerated) generic enumerations (I will fix these after we apply Finn's latest properties patch), a couple of interfaces conflicted name-wise with already existing classes (I just commented those interfaces out--we can forgo those). Also, for classes not implementing Constants, a Constants.InterfaceName.PropertyValue name ends up needing to be used--but for these, we can also easily revert to Constants.PropertyValue. These interfaces are just meant to be a developer convenience, not something required. One (minor) thing I would like to fix though, is that the interfaces are not appearing in alphabetical order in Constants.java (Java [1], XSLT source [2]) (in the XSLT, under the Enumeration Interfaces comment: // Enumeration Interfaces xsl:apply-templates select=document(propfile)//property[not(@type='generic')] / ) [1] http://cvs.apache.org/viewcvs.cgi/xml-fop/src/java/org/apache/fop/fo/Constants.java?rev=1.4view=auto [2] http://cvs.apache.org/viewcvs.cgi/xml-fop/src/codegen/constants.xsl?rev=1.2view=auto I am not an XSLT guru--offhand, does anyone know of a simple way to get the interfaces to appear alphabetically? It's not that big a deal, but there might be something very obvious I've missed, a simple change to get them in alpha order. Thanks, Glen __ Do you Yahoo!? Yahoo!

Re: Comments on new property maker implementation
[Glen Mazza] I've looked at your changes--I like them, and I'm thankful to have someone on our team to be able to redesign the properties as you have. Getting rid of the 250 autogenerated or so classes will be a welcome improvement. But the biggest improvement is IMHO the easy ability to create special maker subclasses to handle the corner cases. Take a look at IndentPropertyMaker for the calculation of start and end-indent and at BorderWidthPropertyMaker for the special handling of border-width when border-style is NONE. Comments right now: 1.) Unlike what I was saying earlier, I don't think we should move from Property.Maker to a new PropertyMaker class after all, your design looks fine. I've noticed most subclasses of Property.Maker are within subclasses of Properties themselves (e.g., LengthProperty, LengthProperty.Maker, etc.) so it looks like a neat, clean design. 2.)

If it is indeed in good shape, I'd like you to submit it to Bugzilla as the new fo-property-mapping.xsl, replacing the old one of that name in src/codegen. Initially my new FOPropertyMapping was generated by XSLT but that is now a long time ago and I have made lots of manual changes since then. The XSLT script only handled the most common property information and was just a hack to get me started. The output isn't a complete java file, it doesn't link the subproperties to the base properties and it doesn't deal with the classname of any of the complex properties. (We won't apply it however, until we no longer need the current autogenerated fo-property-mapping.xsl, i.e., until all the old properties have been tossed out.) This way if we have to make wide-ranging changes to FOPropertyMapping, we'll have a XSLT source file we can conveniently work with. (Note that putting it in codegen does *not* mean that it will be automatically autogenerated anymore--it won't, just as constants.xsl no longer is--we'll pull it out of the main Ant build target at that time and keep it the separate, manual xsltToJava target in our build file[1].

But most of the generic classes are so small (your initialization of GenericCondPadding is only 4 lines of code), that going back to creating concrete classes would be noticeably beneficial either, so I'm not recommending this change. The generic properties are just templates that carries default data values to be used later on, so I don't fully see how we could xslt- generate them as anything other than containers of default values. Your last statement is a bit difficult to parse so I'm not sure what exactly you are recommending. One thing that *does* stick out, however, is the 100 or so addKeyword() calls for genericColor (the largest of the generic properties): genericColor.addKeyword(antiquewhite, #faebd7); genericColor.addKeyword(aqua, #00); genericColor.addKeyword(aquamarine, #7fffd4); . I'd like us to have a static array of these values--i.e., something done compile-time, that genericColor can just reference, so we don't have to do this keyword initialization. I probably need an example of what you thinking are here. Right now in HEAD all the color keywords are stored in a HashMap created in GenericColor so the keywords initialization is already done. Putting the keywords in static array would require us to somehow search the array and I don't see how that will be much faster. You should perhaps also be aware that the values in a static array gets assigned to the array one element at a time. So static int[] a = { 101,102,103,104,105,106,107,108 }; becomes in bytecodes: Method static {} 0 bipush 8 2 newarray int 4 dup 5 iconst_0 6 bipush 101 8 iastore 9 dup 10 iconst_1 11 bipush 102 13 iastore 14 dup 15 iconst_2 16 bipush 103 18 iastore ... and so on for each index. (In case you don't know bytecode by heart, iconst and bipush both push a constant on the stack and iastore pops 3 items from the stack; an index, a value and an array and assign the value to the index in the array). 4) I'd also like us to, rather than call setInherited() and setDefault() for each of the properties during initialization, for the Property/Property.Maker classes to just reference that information from two (new) static arrays, added to Constants.java.

Look up perfect hash code and the associated generators on the internet, like gperf, a C++ implementation used by gcc and a veriety of other compilers to provide a data structure for mapping strings to something else in an efficient way. Mind you, this would also benefit mapping to FO and property names to their associated classes or code numbers. J.Pietschmann

I was always under the impression statically initialized data was stored along with the string constants, like in C. This means a generated perfect has table wouldn't have much of an advantage over, let's say, a simple binary tree loaded with the values in proper order so that the tree becomes automatically balanced (without rotations like rb-trees do). It would make sense, however, to properly initialitze initial size values for the various hashmaps currently used. J.Pietschmann

This change will allow us to take advantage of the fact that we are now on int-constants. getDefault(PR_WHATEVER), for example, is just Constants.DefaultArray[PR_WHATEVER]. I think 'Default' is a bad example, noone ever tries to get the default value except for the property maker itself, but your argument holds for isInherited(). No--I don't think you've gotten my point here. I don't care about the consumers of that information--even if it is just Property.Maker. But I don't see the reason to run-time initialize a PropertyMaker with inherited and default values, because I can add the whole array in the Constants interface, or even in Property.Maker directly. static Boolean inheritedArray[] = { false // 0 true// PR_PROP_1 true// PR_PROP_2 false // PR_PROP_3 true// ... Once you initialize a Property.Maker with its PR_XX constant, *it* (the Maker) can always obtain these values by accessing inheritedArray[PR_XX] or defaultArray[PR_XX]. No reason to initialize via setInherited(true) or setDefault(5). Do you see what I'm trying to say? Still, I disagree. If one want to know is a property is inherited, the proper way to get the information should be to call propertyMapping[PR_WHATEVER].isInherited(). OK--we can place these two arrays in a location where only the Property.Makers can get to it. (Maybe a protected static array in Property.Maker?) Thoughts here? Again, getting rid of the useGeneric() function. This is for more speed, encapsulation, and also shrinking FOPropertyMapping class a bit. A very good idea. +1. I can probably make the modifications to this--looks simple. Thanks, Glen __ Do you Yahoo!? Yahoo! Hotjobs: Enter the Signing Bonus Sweepstakes http://hotjobs.sweepstakes.yahoo.com/signingbonus

Right now in HEAD all the color keywords are stored in a HashMap created in GenericColor so the keywords initialization is already done. Putting the keywords in static array would require us to somehow search the array and I don't see how that will be much faster. You should perhaps also be aware that the values in a static array gets assigned to the array one element at a time. So static int[] a = { 101,102,103,104,105,106,107,108 }; becomes in bytecodes: Method static {} 0 bipush 8 2 newarray int 4 dup 5 iconst_0 6 bipush 101 8 iastore 9 dup 10 iconst_1 11 bipush 102 13 iastore 14 dup 15 iconst_2 16 bipush 103 18 iastore ... and so on for each index. (In case you don't know bytecode by heart, iconst and bipush both push a constant on the stack and iastore pops 3 items from the stack; an index, a value and an array and assign the value to the index in the array). Finn, I can't imagine there is anyone here who doesn't know bytecode by heart. (Except maybe me.) Peter -- Peter B. West http://www.powerup.com.au/~pbwest/resume.html

I didn't realize that there is code being run for static arrays--I would have thought the compiled bytecode just includes the array internally, and not the code to create it. (i.e., if you opened the bytecode you would see an array 101 102 103 104... sitting someplace.) Isn't that how C works, at least? Sigh...I guess I *didn't* know bytecode by heart after all! ;-) Glen __ Do you Yahoo!? Yahoo! Hotjobs: Enter the Signing Bonus Sweepstakes http://hotjobs.sweepstakes.yahoo.com/signingbonus
