Class RebaseImplementationTarget

java.lang.Object

net.bytebuddy.implementation.Implementation.Target.AbstractBase

net.bytebuddy.dynamic.scaffold.inline.RebaseImplementationTarget

All Implemented Interfaces:

Implementation.Target

public class RebaseImplementationTarget
extends Implementation.Target.AbstractBase

An implementation target for redefining a given type while preserving the original methods within the instrumented type.

Super method calls are merely emulated by this Implementation.Target in order to preserve Java's super call semantics a user would expect when invoking a super-prefixed method. This means that original methods are either moved to renamed private methods which are never dispatched virtually or they are invoked directly via the INVOKESPECIAL invocation to explicitly forbid a virtual dispatch.

A method rebase resolver to be used when calling a rebased method.

Constructor Detail

RebaseImplementationTarget

protected RebaseImplementationTarget(MethodLookupEngine.Finding finding,
                                     BridgeMethodResolver.Factory bridgeMethodResolverFactory,
                                     MethodRebaseResolver methodRebaseResolver)

Creates a rebase implementation target.

Parameters:

finding - The lookup of the instrumented type this instance should represent.

bridgeMethodResolverFactory - A factory for creating a bridge method resolver.

methodRebaseResolver - A method rebase resolver to be used when calling a rebased method.

Method Detail

invokeSuper

protected Implementation.SpecialMethodInvocation invokeSuper(MethodDescription methodDescription)

Description copied from class: Implementation.Target.AbstractBase

Invokes the fully resolved method to be invoked by a super method call.

Specified by:

invokeSuper in class Implementation.Target.AbstractBase

Parameters:

methodDescription - The method that is to be invoked specially.

Returns:

A special method invocation for calling the super method.

getOriginType

public TypeDescription getOriginType()

Description copied from interface: Implementation.Target

Identifies the origin type of an implementation. The origin type describes the type that is subject to any form of enhancement. If a subclass of a given type is generated, the base type of this subclass describes the origin type. If a given type is redefined or rebased, the origin type is described by the instrumented type itself.

Returns:

The origin type of this implementation.

equals

public boolean equals(Object other)

Overrides:

equals in class Implementation.Target.AbstractBase

hashCode

public int hashCode()

Overrides:

hashCode in class Implementation.Target.AbstractBase

toString

public String toString()

Overrides:

toString in class Object
