onBeforeTransform

@MaybeNull
T onBeforeTransform(@MaybeNull
                               JavaModule module,
                               @MaybeNull
                               ClassLoader classLoader,
                               @MaybeNull
                               String internalName,
                               @MaybeNull
                               Class<?> classBeingRedefined,
                               @MaybeNull
                               ProtectionDomain protectionDomain,
                               byte[] binaryRepresentation)
                        throws IllegalClassFormatException

Invoked before the transformation is applied.

Parameters:

module - The instrumented class's Java module or null if the module system is not supported.

classLoader - The type's class loader or null if the type is loaded by the bootstrap loader.

internalName - The internal name of the instrumented class.

classBeingRedefined - The loaded Class being redefined or null if no such class exists.

protectionDomain - The instrumented type's protection domain or null if not available.

binaryRepresentation - The class file of the instrumented class in its current state.

Returns:

A value to pass to the method that is invoked after transformation or null.

Throws:

IllegalClassFormatException - If the class file was found invalid.

onAfterTransform

void onAfterTransform(@MaybeNull
                      T value,
                      @MaybeNull
                      JavaModule module,

                      byte[] binaryRepresentation)
               throws IllegalClassFormatException

Invoked after the transformation is applied.

Parameters:

value - The value that was returned before transformation.

module - The instrumented class's Java module or null if the module system is not supported.

internalName - The internal name of the instrumented class.

classBeingRedefined - The loaded Class being redefined or null if no such class exists.

protectionDomain - The instrumented type's protection domain or null if not available.

binaryRepresentation - The class file of the instrumented class in its current state.

Throws:
