The documentation of rexxref.pdf chapter "5.1.4.12. instanceMethods" has a documentation bug that
Josep Maria referred to (# 317, https://sourceforge.net/p/oorexx/documentation/317/) and supplied a
patch for it.
Looking into the patch and then into the example that should be working correctly (ooRexx 5.1.0 in
this case), it seems that the method "instanceMethods" without an argument does not return the
complete list of class methods for the String class.
Here using instanceMethods on the .class objects involved for the .string class (.object, .class,
.string):
say .context~name"(".context~executable~class~id")" say sum=0
allMethods1=.bag~new
do clzover .Class,.Object,.String
clzMethods=ppIndexes(clz~instanceMethods(clz))
items=clzMethods~items
sum+=items
say clz~id":" items"class methods" say clzMethods~makeString(,', ')
allMethods1=allMethods1~union(clzMethods)
say "---" say end say "total of:" sum
say "allMethods1~items:" allMethods1~items
say "allMethods1:" allMethods1~allIndexes~sort~makeString(,', ')
say say "-"~copies(79)
clzMethods=ppIndexes(.string~instanceMethods)
allMethods2=.bag~new~union(clzMethods)
say .string~id":" clzMethods~items
say "allMethods2~items:" allMethods2~items
say clzMethods~makeString(,', ')
say say "-"~copies(79)
say say "allMethods2:" allMethods2~allIndexes~sort~makeString(,', ')
say say "allMethods1~difference(allMethods2):"
allMethods1~difference(allMethods2)~makearray~sort~makeString(,',')
say "allMethods2~difference(allMethods1):"
allMethods2~difference(allMethods1)~makearray~sort~makeString(,',')
::routine pp
return "["arg(1)"]" ::routine ppIndexes
use arg o
arrOut=.array~new
do valover o~allindexes~sort
arrOut~append(pp(val))
end return arrOut
Running this program shows at the end the following output:
allMethods1~difference(allMethods2): [NEW]
allMethods2~difference(allMethods1):
Indeed there is a NEW method in .Object, one in .Class, and one in .String, if querying
.Object~instanceMethods(.Object), .Class~instanceMethods(.Class), and
.String~instanceMethods(.String), totalling three NEW methods (they are included in "allMethods1").
However .String~instanceMethods only returns two NEW methods (see "allMethods2") instead of three,
hence the discrepancy.
Why would that be?
