Constructor Detail

MethodLoading

protected MethodLoading(MethodDescription methodDescription,
                        MethodVariableAccess.MethodLoading.TypeCastingHandler typeCastingHandler)

Creates a new method loading stack manipulation.

Parameters:

methodDescription - The method for which all parameters are loaded onto the operand stack.

typeCastingHandler - A type casting handler which is capable of transforming all method parameters.

Method Detail

apply

public StackManipulation.Size apply(MethodVisitor methodVisitor,
                                    Implementation.Context implementationContext)

Applies the stack manipulation that is described by this instance.

Parameters:

methodVisitor - The method visitor used to write the method implementation to.

implementationContext - The context of the current implementation.

Returns:

The changes to the size of the operand stack that are implied by this stack manipulation.

prependThisReference

public StackManipulation prependThisReference()

Prepends a reference to the this instance to the loaded parameters if the represented method is non-static.

Returns:

A stack manipulation that loads all method parameters onto the operand stack while additionally loading a reference to this if the represented is non-static. Any potential parameter transformation is preserved.

asBridgeOf

public MethodVariableAccess.MethodLoading asBridgeOf(MethodDescription bridgeTarget)

Applies a transformation to all loaded arguments of the method being loaded to be casted to the corresponding parameter of the provided method. This way, the parameters can be used for invoking a bridge target method.

Parameters:

bridgeTarget - The method that is the target of the bridge method for which the parameters are being loaded.

Returns:

A stack manipulation that loads all parameters casted to the types of the supplied bridge target.
