Constructor Detail

WithStackSizeComputation

protected WithStackSizeComputation(MethodDescription.InDefinedShape instrumentedMethod,
                                   List<? extends TypeDescription> requiredTypes,
                                   List<? extends TypeDescription> yieldedTypes,
                                   boolean expandFrames)

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.

expandFrames - true if this meta data handler is expected to expand its written frames.

Method Detail

compoundStackSize

public int compoundStackSize(int stackSize)

Description copied from interface: Advice.MetaDataHandler.ForInstrumentedMethod

Computes a compound stack size for the advice and the translated instrumented method.

Parameters:

stackSize - The required stack size of the instrumented method before translation.

Returns:

The stack size required by the instrumented method and its advice methods.

compoundLocalVariableLength

public int compoundLocalVariableLength(int localVariableLength)

Description copied from interface: Advice.MetaDataHandler.ForInstrumentedMethod

Computes a compound local variable array length for the advice and the translated instrumented method.

Parameters:

localVariableLength - The required local variable array length of the instrumented method before translation.

Returns:

The local variable length required by the instrumented method and its advice methods.

bind

protected Advice.MetaDataHandler.Default.ForAdvice bind(MethodDescription.InDefinedShape methodDescription,
                                                        TypeList requiredTypes,
                                                        List<? extends TypeDescription> yieldedTypes,
                                                        Advice.MetaDataHandler.Default.TranslationMode translationMode)

Description copied from class: Advice.MetaDataHandler.Default

Binds the given advice method to an appropriate meta data handler.

Specified by:

bind in class Advice.MetaDataHandler.Default

Parameters:

methodDescription - The advice method.

requiredTypes - The expected types that the advice method requires additionally to the instrumented method's parameters.

yieldedTypes - The types this advice method yields as additional parameters.

translationMode - The translation mode to apply for this advice.

Returns:

An appropriate meta data handler.

toString

public String toString()

Overrides:

toString in class Object
