Interface ClassVisitorWrapper

All Known Implementing Classes:

ClassVisitorWrapper.Chain

public interface ClassVisitorWrapper

A class visitor wrapper is used in order to register an intermediate ASM ClassVisitor which is applied to the main type created by a DynamicType.Builder but not to any AuxiliaryTypes, if any.

Nested Class Summary

static class	ClassVisitorWrapper.Chain An ordered, immutable chain of ClassVisitorWrappers.

Method Summary

Modifier and Type	Method and Description
int	mergeReader(int hint) Defines a hint that is provided to any ClassReader when reading a class if applicable.
int	mergeWriter(int hint) Defines a hint that is provided to any ClassWriter when writing a class.
ClassVisitor	wrap(ClassVisitor classVisitor) Applies a ClassVisitorWrapper to the creation of a DynamicType.

Method Detail

mergeWriter

int mergeWriter(int hint)

Defines a hint that is provided to any ClassWriter when writing a class. Typically, this gives opportunity to instruct ASM to compute stack map frames or the size of the local variables array and the operand stack. If no specific hints are required for applying this wrapper, the given value is to be returned.

Parameters:

hint - The current hint. This value should be merged (e.g. hint | foo) into the value that is returned by this wrapper.

Returns:

The hint to be provided to the ASM ClassWriter.

mergeReader

int mergeReader(int hint)

Defines a hint that is provided to any ClassReader when reading a class if applicable. Typically, this gives opportunity to instruct ASM to expand or skip frames and to skip code and debug information. If no specific hints are required for applying this wrapper, the given value is to be returned.

Parameters:

hint - The current hint. This value should be merged (e.g. hint | foo) into the value that is returned by this wrapper.

Returns:

The hint to be provided to the ASM ClassReader.

wrap

ClassVisitor wrap(ClassVisitor classVisitor)

Applies a ClassVisitorWrapper to the creation of a DynamicType.

Parameters:

classVisitor - A ClassVisitor to become the new primary class visitor to which the created DynamicType is written to.

Returns:

A new ClassVisitor that usually delegates to the ClassVisitor delivered in the argument.
