Package org.aopalliance.instrument
This package provides an API for program instrumentation.
This package provides a set of interfaces for applying
intrumentations on a program, i.e. a program modification which
adds some feature (methods, classes, code) to the original
program. These instrumentations are abstractly defined and can
occur at compile-time, load-time, or runtime depending on the
Instrumentor
implementation. Moreover, since it uses the org.aopalliance.reflect
package which provides an abstract
representation of the program, the instrumentations can be
implemented at a source-code level or at a bytecode level,
depending on the implementation.
This API is specific to AOP. This means that the set of program instrumentations that is allowed is a restricted set compared to a general-purpose API. However, general-purpose transformation tools should provide an implementation of this API in order to be easily used by several AO systems.
Dependencies
This package requires the org.aopalliance.reflect
package.

ClassDescriptionThis interface represents an instrumentation on the base program.The error that is raised when an error occurs during an instrumentation.This interface defines all the methods that perform program instrumentations that are useful for AOP.The exception that is raised when the client program tries to undo an instrumentation and when current implementation does not support it.
