public interface SignatureVisitor
A visitor to visit a generic signature. The methods of this interface must be called in one of the three following orders (the last one is the only valid order for a SignatureVisitor that is returned by a method of this interface):
  • ClassSignature = ( visitFormalTypeParameter visitClassBound? visitInterfaceBound* )* ( visitSuperClass visitInterface* )
  • MethodSignature = ( visitFormalTypeParameter visitClassBound? visitInterfaceBound* )* ( visitParameterType* visitReturnType visitExceptionType* )
  • TypeSignature = visitBaseType | visitTypeVariable | visitArrayType | ( visitClassType visitTypeArgument* ( visitInnerClassType visitTypeArgument* )* visitEnd ) )

    • visitFormalTypeParameter

      void visitFormalTypeParameter(String name)
      Visits a formal type parameter.
      Parameters:
      name - the name of the formal parameter.

    • visitClassBound

      SignatureVisitor visitClassBound()
      Visits the class bound of the last visited formal type parameter.
      Returns:
      a non null visitor to visit the signature of the class bound.

    • visitInterfaceBound

      SignatureVisitor visitInterfaceBound()
      Visits an interface bound of the last visited formal type parameter.
      Returns:
      a non null visitor to visit the signature of the interface bound.

    • visitSuperclass

      SignatureVisitor visitSuperclass()
      Visits the type of the super class.
      Returns:
      a non null visitor to visit the signature of the super class type.

    • visitInterface

      SignatureVisitor visitInterface()
      Visits the type of an interface implemented by the class.
      Returns:
      a non null visitor to visit the signature of the interface type.

    • visitParameterType

      SignatureVisitor visitParameterType()
      Visits the type of a method parameter.
      Returns:
      a non null visitor to visit the signature of the parameter type.

    • visitReturnType

      SignatureVisitor visitReturnType()
      Visits the return type of the method.
      Returns:
      a non null visitor to visit the signature of the return type.

    • visitExceptionType

      SignatureVisitor visitExceptionType()
      Visits the type of a method exception.
      Returns:
      a non null visitor to visit the signature of the exception type.

    • visitBaseType

      void visitBaseType(char descriptor)
      Visits a signature corresponding to a primitive type.
      Parameters:
      descriptor - the descriptor of the primitive type, or 'V' for void.

    • visitTypeVariable

      void visitTypeVariable(String name)
      Visits a signature corresponding to a type variable.
      Parameters:
      name - the name of the type variable.

    • visitArrayType

      SignatureVisitor visitArrayType()
      Visits a signature corresponding to an array type.
      Returns:
      a non null visitor to visit the signature of the array element type.

    • visitClassType

      void visitClassType(String name)
      Starts the visit of a signature corresponding to a class or interface type.
      Parameters:
      name - the internal name of the class or interface.

    • visitInnerClassType

      void visitInnerClassType(String name)
      Visits an inner class.
      Parameters:
      name - the local name of the inner class in its enclosing class.

    • visitTypeArgument

      void visitTypeArgument()
      Visits an unbounded type argument of the last visited class or inner class type.

    • visitTypeArgument

      SignatureVisitor visitTypeArgument(char wildcard)
      Visits a type argument of the last visited class or inner class type.
      Parameters:
      wildcard - '+', '-' or '='.
      Returns:
      a non null visitor to visit the signature of the type argument.

    • visitEnd

      void visitEnd()
      Ends the visit of a signature corresponding to a class or interface type.
