Method Summary

Modifier and Type	Method	Description
static ClassSignature	of(Signature.ClassTypeSig superclassSignature, Signature.ClassTypeSig... superinterfaceSignatures)	Returns a class signature with no type parameter declaration.
static ClassSignature	of(List<Signature.TypeParam> typeParameters, Signature.ClassTypeSig superclassSignature, Signature.ClassTypeSig... superinterfaceSignatures)	Returns a class signature.
static ClassSignature	parseFrom(String classSignature)	Parses a raw class signature string into a Signature.
String	signatureString()	Returns the raw signature string.
Signature.ClassTypeSig	superclassSignature()	Returns the instantiation of the superclass in this signature.
List<Signature.ClassTypeSig>	superinterfaceSignatures()	Returns the instantiation of the interfaces in this signature, may be empty.

superinterfaceSignatures

List<Signature.ClassTypeSig> superinterfaceSignatures()

Returns the instantiation of the interfaces in this signature, may be empty.

Returns:

the instantiation of the interfaces in this signature, may be empty
