Re: PropertyHelper API
Yes, I think that I added the null return to allow local properties.

Hi
I'm trying to grok the changes to the PropertyHelper in
order to
document them for 1.8.0 - and maybe to suggest throwing in
some more
built-in delegates, but that's for a different thread.
From what I understand:
The default PropertyHelper splits its work into several
steps that can
be delegated to custom implementations. These steps
are:
* finding a property reference inside a string.
The delegate interface is
oata.property.PropertyExpander.
There are two built-in expanders, one that
finds ${foo} positions
the parser after the '}' and says here is
property foo' and one
that finds $$, positions the parser after the
second $ (actually at
the second $) and says no property to be
seen here.
This is the interface I'd implement if I
wanted a completely
different property syntax. I'd also
need to implement it if I
wanted to allow nested properties ${${foo}}
since the default
PropertyExpander doesn't balance braces.
Note that the props antlib does provide a NestedPropertyExpander, so you're
right on track.
* mapping a property to a value
The delegate interface is
oata.PropertyHelper.PropertyEvaluator.
There are two built-in implementations, one
implements local
properties and one implements the toString:
protocol,
i.e. ${toString:some-refid} =
find-reference-in-project.toString()
This is the interface I'd implement if I
- want to provide a different protocol like
toString:
- want to provide a different storage for
properties, this would be
the reading part of it.
Normal project properties are not
implemented via
PropertyEvaluator but implemented via
fallback mechanisms in the
default PropertyHelper implementation.
PropertyEvaluator can return Object but it
will be turned into a
String unless the whole string that was
expanded is consumed by the
property (i.e. ${foo} can become an Object
while ${foo} bar van
not).
PropertyEvaluator can return an instance of
the magical
oata.property.NullReturn class which means I
really really mean it
when I say the property expands to null
because simply returning
null means I don't know this property.
* storing the value for a property somewhere
The delegate interface is
oata.PropertyHelper.PropertySetter.
The only built-in implementation is for local
properties.
This is the interface I'd implement if I
- want to provide a different storage for
properties, this would be
the writing part of it.
Normal project properties are not
implemented via
PropertySetter but implemented via fallback
mechanisms in the
default PropertyHelper implementation.
PropertySetter returns a flag indicating
whether it has consumed the
property - otherwise the other delegates are
consulted and
ultimately the fallback to project properties
is used.
The properthelper task can be used to register
custom delegates.
Delegates are used in LIFO order that is custom delegates
are able to
override built-in delegates.
Is this correct and somewhat complete (Matt?)?
The NullReturn thing, IIRC, was added by Peter. But I think you're correct
about it. Everything else sounds correct and complete as well; my proverbial
hat is off to you for having compiled this comprehensive piece of
documentation.

how to call a predefined target or macroin build.xml from Custom Ant task
Hi, I am looking to call a Macro defined in the project though custom task. Similarly calling of target. Both macro and target are defined the build.xml and my java based custom task should be able to call it with min overhead.. i.e with the same overhead as calling the macro from build.xml or calling one target from other either by depends.

Peformance Task usage from custom task
Hi, Is it possible to set the performance monitoring as described in http://antelope.tigris.org/nonav/docs/manual/bk03ch27.html (i.e enable and disable such data collection) from a custom ant tasks java code. My need to enable monitoring only during the execution of the custom task and remove it once that is executed. Also, I am not interested to change the ant launch time parameters as this would impact entire build completion and not ideal for our needs.

Re: Peformance Task usage from custom task
From a custom task, you have access to a Project object, which has both add and remove build listener methods, which means you should be able to add and remove listeners on the fly. I haven't tried this, but I don't see why it wouldn't work.

According to your stacktrace the NPE occurs in line 62 of the listener Its source is available here: http://ant-contrib.svn.sourceforge.net/viewvc/ant-contrib/ant-contrib/trunk/src/main/java/net/sf/antcontrib/perf/AntPerformanceListener.java?revision=130view=markup long stop_time = master.stop(); So 'master' is null.
