Class SignatureVisitor

  • Direct Known Subclasses:
    SignatureWriter
    public abstract class SignatureVisitor
extends Object
    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

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

      • visitClassBound

        public 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

        public 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

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

      • visitInterface

        public 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

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

      • visitReturnType

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

      • visitExceptionType

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

      • visitBaseType

        public 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

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

      • visitArrayType

        public 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

        public 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

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

      • visitTypeArgument

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

      • visitTypeArgument

        public 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

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