Constructor Detail

Simple

protected Simple(MethodDescription methodDescription,
                 TypeDescription typeDescription,
                 StackManipulation stackManipulation)

Creates a new legal special method invocation.

Parameters:

methodDescription - The method that represents the special method invocation.

typeDescription - The type on which the method should be invoked on by an INVOKESPECIAL invocation.

stackManipulation - The stack manipulation that represents this special method invocation.

Method Detail

of

public static Instrumentation.SpecialMethodInvocation of(MethodDescription methodDescription,
                                                         TypeDescription typeDescription)

Creates a special method invocation for a given invocation target.

Parameters:

methodDescription - The method that represents the special method invocation.

typeDescription - The type on which the method should be invoked on by an INVOKESPECIAL invocation.

Returns:

A special method invocation representing a legal invocation if the method can be invoked specially on the target type or an illegal invocation if this is not possible.

getMethodDescription

public MethodDescription getMethodDescription()

Description copied from interface: Instrumentation.SpecialMethodInvocation

Returns the method that represents this special method invocation. This method can be different even for equal special method invocations, dependant on the method that was used to request such an invocation by the means of a Instrumentation.Target.

Specified by:

getMethodDescription in interface Instrumentation.SpecialMethodInvocation

Returns:

The method description that describes this instances invocation target.

getTypeDescription

public TypeDescription getTypeDescription()

Description copied from interface: Instrumentation.SpecialMethodInvocation

Returns the target type the represented method is invoked on.

Specified by:

getTypeDescription in interface Instrumentation.SpecialMethodInvocation

Returns:

The type the represented method is invoked on.

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,
                                    Instrumentation.Context instrumentationContext)

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.

instrumentationContext - The context of the current instrumentation.

Returns:

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