IMethod.getParameterTypes() - Source vs Binary method signatures [message #1814266]

Hello,

When I call getParameterTypes() on SOURCE methods, I get signature types where for example "java.lang.String" shows up as "QString".

This does not happen forBINARY methods where this shows up as a regular "java.lang.String".

Is there a way to get this kind of signature for source methods? I would like to always get the behaviour of binary methods (i.e. "java.lang.String")

For binary methods the fully qualified name comes for free (it's directly found in the byte code).

For source methods the light-weight Java Model does not directly provide this information. You have two options:
- go through ASTParser.createBindings() to obtain the bindings with full resolved type names, or
- try using IType.resolveType(), but you may have to first call Signature.toString(type) to get rid of the "Q...;" part

If you are dealing with many types, then surely the approach using ASTParser.createBindings() performs better, as it can compute many bindings in one go.
