Class SignatureVisitor

  • Direct Known Subclasses:
    CheckSignatureAdapter, SignatureRemapper, SignatureWriter, TraceSignatureVisitor

    public abstract class SignatureVisitor
    extends java.lang.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 ) )

        a non null visitor to visit the signature of the parameter type.
      • visitReturnType

        public SignatureVisitor visitReturnType()
        Visits the return type of the method.

        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​(java.lang.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.
