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 ) )

Method Detail

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()

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()

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.
