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.
Cheers
Thomas

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!

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 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

(ICIO

(LOC

(LOCOMM

(LDA

(MAXNESTING 1.00)
(NOAV

(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
