Constructor Detail

Simple

public Simple(ByteCodeAppender... byteCodeAppender)

Creates a new simple instrumentation for the given byte code appenders.

Parameters:

byteCodeAppender - The byte code appenders to apply in their order of application.

Simple

public Simple(StackManipulation... stackManipulation)

Creates a new simple instrumentation for the given stack manipulations which are summarized in a byte code appender that defines any requested method by these manipulations.

Parameters:

stackManipulation - The stack manipulation to apply in their order of application.

Method Detail

prepare

public InstrumentedType prepare(InstrumentedType instrumentedType)

Description copied from interface: Instrumentation

During the preparation phase of an instrumentation, implementations are eligible to adding fields or methods to the currently instrumented type. All methods that are added by this instrumentation are required to be implemented by the ByteCodeAppender that is emitted on the call to Instrumentation.appender(net.bytebuddy.instrumentation.Instrumentation.Target) call. On this method call, loaded type initializers can also be added to the instrumented type.

Specified by:

prepare in interface Instrumentation

Parameters:

instrumentedType - The instrumented type that is the basis of the ongoing instrumentation.

Returns:

The instrumented type with any applied changes, if any.

appender

public ByteCodeAppender appender(Instrumentation.Target instrumentationTarget)

Description copied from interface: Instrumentation

Creates a byte code appender that determines the implementation of the instrumented type's methods.

Specified by:

appender in interface Instrumentation

Parameters:

instrumentationTarget - The target of the current instrumentation.

Returns:

A byte code appender for implementing methods delegated to this instrumentation. This byte code appender is also responsible for handling methods that were added by this instrumentation on the call to Instrumentation.prepare(net.bytebuddy.instrumentation.type.InstrumentedType).

equals

public boolean equals(Object other)
