Constructor Detail

Chain

public Chain()

Creates an immutable empty chain.

Chain

protected Chain(List<ClassVisitorWrapper> classVisitorWrappers)

Creates a new immutable chain based on an existing list of ClassVisitorWrappers where no copy of the received list is made.

Parameters:

classVisitorWrappers - A list of ClassVisitorWrappers where elements at the beginning of the list are applied first, i.e. will be at the bottom of the generated ClassVisitor.

Method Detail

prepend

public ClassVisitorWrapper.Chain prepend(ClassVisitorWrapper classVisitorWrapper)

Adds a ClassVisitorWrapper to the beginning of the chain such that the wrapped ASM ClassVisitor will be applied before the other class visitors.

Parameters:

classVisitorWrapper - The ClassVisitorWrapper to add to the beginning of the chain.

Returns:

A new chain incorporating the ClassVisitorWrapper.

append

public ClassVisitorWrapper.Chain append(ClassVisitorWrapper classVisitorWrapper)

Adds a ClassVisitorWrapper to the end of the chain such that the wrapped ASM ClassVisitor will be applied after the other class visitors.

Parameters:

classVisitorWrapper - The ClassVisitorWrapper to add to the end of the chain.

Returns:

A new chain incorporating the ClassVisitorWrapper.

mergeWriter

public int mergeWriter(int hint)

Description copied from interface: ClassVisitorWrapper

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.

Specified by:

mergeWriter in interface ClassVisitorWrapper

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

public int mergeReader(int hint)

Description copied from interface: ClassVisitorWrapper

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.

Specified by:

mergeReader in interface ClassVisitorWrapper

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

public ClassVisitor wrap(ClassVisitor classVisitor)

Description copied from interface: ClassVisitorWrapper

Applies a ClassVisitorWrapper to the creation of a DynamicType.

Specified by:

wrap in interface ClassVisitorWrapper

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.

equals

public boolean equals(Object other)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object
