Method Detail

visitFormalTypeParameter

void visitFormalTypeParameter(java.lang.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()

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

Returns:
a non null visitor to visit the signature of the array element type.

visitClassType

void visitClassType(java.lang.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(java.lang.String name)
Visits an inner class.

Parameters:
name - the local name of the inner class in its enclosing class.

visitTypeArgument

void visitTypeArgument()
