I thought it might
be nice to have a list of valid method names when initiating an object so I'd be
able to make sure I didn't try to run a method (perhaps based on user input)
that was inappropriate. Of course, I could use try/catch but that wouldn't
distinguish between calling invalid methods and errors within the
method.
Anyhow,
getMetaData() works fine, but I ran into problems getting a clean method
list:
<cfset Local.TempMetaData =
getMetaData(THIS)>
<cfset Local.FunctionList = Local.TempMetaData.Functions>
<cfset THIS.MethodList = Local.FunctionList[1].Name>
<cfset Local.FunctionList = Local.TempMetaData.Functions>
<cfset THIS.MethodList = Local.FunctionList[1].Name>
Successfully returns
the name of the first method of the object.
Trying to loop
through them as below gives "Invalid collection "[Ljava.lang.Object;@1f4c4a3" -
must be a valid struct or COM object. "
<cfloop collection="#Local.FunctionList#"
item="Count">
<cfset ThisVal = Local.FunctionList[#Count#].Name>
<cfset THIS.MethodList = ListAppend(THIS.MethodList,ThisVal)>
</cfloop>
<cfset ThisVal = Local.FunctionList[#Count#].Name>
<cfset THIS.MethodList = ListAppend(THIS.MethodList,ThisVal)>
</cfloop>
I have a feeling
this is a simple syntax problem but am not sure . . . Anyone have simple code
for returning a list of methods?
FYI, I know Sean
suggested some time back that run time introspection doesn't scale, but by only
running this routine on a small number of objects that I persist throughout an
application and by only calling it once on object creation I'm betting the
performance overhead will be minimal.
Best
Wishes,
Peter
