Description

To facilitate use of java with OCL, provide some function such as

static OclAny::oclCall(returnType : Class(T), qualifiedFunctionName : String, args : Sequence(OclAny)) : T

allowing e.g.

oclCall(String, 'java.lang.String.toUpper', Sequence{aString})

function argument types are not needed on the qualifiedFunctionName since they are deducible from the arguments sequence.

It can be much more regular with the aid of quoted identifiers.

'java::java.lang.String'::toUpper(aString)

(In reply to Ed Willink from comment #1)

It can be much more regular with the aid of quoted identifiers.

'java::java.lang.String'::toUpper(aString)

No, escaped identifiers are spelled _'...', XML single colon namespace qualifier seems more logical than double colon OCL scope qualification, so

_'java:java.lang.String'::toUpper(aString)

---

seems to work.

Needs an extension point to declare "java" support without promoting codegen functionality to pivot.

Needs care to handle statics consistently and provide diverse error messages.

Auseful example such as String.format has a varargs parameter which doesn't merit special support so we can rquire an explicot Sequence: e.g.

_'java:java.lang.String.format'('The result is %4.4f,%2d\n', Sequence(OclAny){7.7,33})

Bug 370087 identifies conversion delegate opportunities once a Java calling interface is available.
