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

isValid

public boolean isValid()

Description copied from interface: StackManipulation

Determines if this stack manipulation is valid.

Specified by:

isValid in interface StackManipulation

Returns:

If false, this manipulation cannot be applied and should throw an exception.

apply

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

Description copied from interface: StackManipulation

Applies the stack manipulation that is described by this instance.

Specified by:

apply in interface StackManipulation

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.
