Hi everybody,
I hope my question is not off topic: I am currently trying to figure out how to describe generic methods in Famix 3.0 (for the .NET FamixGenerator) For example in Java you can write the following code. public class ClassWithGenericMethod { public static <TResult> TResult getTheGeneric(String resource) { return null; }
public static <TValue> void useTheGeneric(TValue value) { System.out.println("value '"+value +"' type: "+value.getClass()); }
If I run InFamix on this code I get an Famix file containing something like:
1 method: (FAMIX.Method (id: 24) (sourceAnchor (ref: 60)) (parentType (ref: 30)) (declaredType (ref: 33)) (name 'getTheGeneric') (signature 'getTheGeneric(_unknown_path::String)') (hasClassScope true) (isPublic true) (isPureAccessor true) (ATFD 0.00) (ALD 0.00) (CYCLO 1.00) (DR 0.00) (ICDO 1.00) (ICIO 1.00) (LOC 3.00) (LOCOMM 1.00) (LDA 1.00) (MAXNESTING 1.00) (NOAV 0.00) (NOOC 0.00) (NOPAR 1.00) (OCDO 0.00) (OCIO 0.00) )
But id 33 is not existing.
2 method: (FAMIX.Method (id: 25) (sourceAnchor (ref: 61)) (parentType (ref: 30)) (declaredType (ref: 28)) (name 'useTheGeneric') (signature 'useTheGeneric(_unknown_path::TValue)') (hasClassScope true) (isPublic true) (ATFD 0.00) (ALD 0.00) (CYCLO 1.00) (DR 0.00) (ICDO 1.00) (ICIO 1.00) (LOC 3.00) (LOCOMM 1.00) (LDA 1.00) (MAXNESTING 1.00) (NOAV 2.00) (NOOC 2.00) (NOPAR 1.00) (OCDO 0.00) (OCIO 0.00) )
(FAMIX.Parameter (id: 35) (name 'value') (parentBehaviouralEntity (ref: 25)) (declaredType (ref: 36)) (position 0) )
But id 36 is not existing.
I am wondering if there should be something like ParameterizableMethod (like ParameterizableClass?
Can anybody give me some clues?
Thank you very much Thomas

Hi Thomas,
sorry I did not spot this email earlier.
Here's what I get with VerveineJ:
(FAMIX.Method (id: 58) (name 'getTheGeneric') (cyclomaticComplexity 1) (declaredType (ref: 28)) (hasClassScope true) (modifiers 'public') (numberOfStatements 1) (parentType (ref: 17)) (signature 'getTheGeneric(String)') (sourceAnchor (ref: 57))) (FAMIX.Type (id: 28) (name 'TResult') (container (ref: 58)) (isStub true))
so TResult is simply a type defined by the method getTheGeneric. Same goes for TValue There is nothing special marking them as "VariableTypes"
(FAMIX.Method (id: 34) (name 'useTheGeneric') (cyclomaticComplexity 1) (declaredType (ref: 50)) (hasClassScope true) (modifiers 'public') (numberOfStatements 2) (parentType (ref: 17)) (signature 'useTheGeneric(TValue)') (sourceAnchor (ref: 37))) (FAMIX.Parameter (id: 36) (name 'value') (declaredType (ref: 14)) (parentBehaviouralEntity (ref: 34))) (FAMIX.Type (id: 14) (name 'TValue') (container (ref: 34)) (isStub true))

PS: I see that verveineJ treat them as stubs. I am not sure whether this is right. It should probably not ...

Hi Nicolas ,
thank you for your answer and explanation. I would have hoped that generic methods would be expressed similar to generic types/classes.
But "binding" the generic Types like TValue to the method seem to make sense and it is consistent to the way generic classes are handled in InFamix, e.g:
(FAMIX.ParameterizableClass (id: 154) (sourceAnchor (ref: 784753)) (isStub true) (parentPackage (ref: 5)) (name 'HashMap') )
(FAMIX.ParameterType (id: 155) (name 'K') (container (ref: 154)) )
But how do you handle concrete usages of the generic method like ClassWithGenericMethod.useTheGeneric("hi generic method"); // type inference ClassWithGenericMethod.useTheGeneric(1.5d); // type inference
InFamix generates the following:
(FAMIX.Invocation (sender (ref: 19)) (candidates (ref: 25)) (signature 'useTheGeneric(_unknown_path::TValue)') )
(FAMIX.Invocation (sender (ref: 19)) (candidates (ref: 25)) (signature 'useTheGeneric(_unknown_path::TValue)') )
based on the source code. It does not "detect" the concrete types. If you would parse compiled code this might change...
Thanks once again for your feedback! Thomas

Hi Nicolas,
I have now released a new version of the FamixGenerator (http://www.sharpmetrics.net/index.php/famix-generator), which handles generic Methods similar to VerveineJ.

Hi Thomas,
sorry I did not spot this email earlier.
Here's what I get with VerveineJ:
(FAMIX.Method (id: 58)
(name 'getTheGeneric')
(cyclomaticComplexity 1)
(declaredType (ref: 28))
(hasClassScope true)
(modifiers 'public')
(numberOfStatements 1)
(parentType (ref: 17))
(signature 'getTheGeneric(String)')
(sourceAnchor (ref: 57)))
(FAMIX.Type (id: 28)
(name 'TResult')
(container (ref: 58))
(isStub true))
so TResult is simply a type defined by the method getTheGeneric.
Same goes for TValue
There is nothing special marking them as "VariableTypes"
(FAMIX.Method (id: 34)
(name 'useTheGeneric')
(cyclomaticComplexity 1)
(declaredType (ref: 50))
(hasClassScope true)
(modifiers 'public')
(numberOfStatements 2)

(signature 'useTheGeneric(TValue)')
(sourceAnchor (ref: 37)))
