Constructor Detail

Default

protected Default(MethodDescription.InDefinedShape instrumentedMethod,
                  TypeList requiredTypes,
                  TypeList yieldedTypes)

Creates a new default meta data handler that recomputes the space requirements of an instrumented method.

Parameters:

instrumentedMethod - The instrumented method.

requiredTypes - The types this meta data handler expects to be available additionally to the instrumented method's parameters.

yieldedTypes - The types that are expected to be added after the instrumented method returns.

                                             int writerFlags)

Creates a method size handler applicable for the given instrumented method.

Parameters:

instrumentedMethod - The instrumented method.

requiredTypes - The list of types that the instrumented method requires in addition to the method parameters.

yieldedTypes - A list of types that are yielded by the instrumented method and available to the exit advice.

writerFlags - The flags supplied to the ASM class writer.

Returns:

An appropriate method size handler.
