Direct Known Subclasses:
SignatureRemapper, 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 ) )

  • Field Details

    • EXTENDS

      public static final char EXTENDS
