Constructor Detail

PrivilegedLookup

protected PrivilegedLookup(MethodDescription.InDefinedShape methodDescription,
                           StackManipulation methodName)

Creates a new privileged lookup.

Parameters:

methodDescription - The method constant to load.

methodName - The stack manipulation for locating the method name.

Method Detail

isValid

public boolean isValid()

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

                                    Implementation.Context implementationContext)

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.

cached

public StackManipulation cached()

Returns this method constant as a cached version.

Specified by:

cached in interface MethodConstant.CanCache

Returns:

A cached version of the method constant that is represented by this instance.

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals
