transformIntoResumableBytes

public static byte[] transformIntoResumableBytes(ContinuationConfigInstrument configInstrument,
                                                 byte[] rawBytes,
                                                 String classname)
                                          throws ClassNotFoundException

Perform the class transformation.

If the class doesn't implement the marker interface that is setup in the instrumentation config, the original bytes will be returned.

Parameters:

configInstrument - the configuration for the instrumentation

rawBytes - the raw bytes of the class to instrument

classname - the name of the class to instrument

Returns:

a byte array with the instrumented bytecode; or

the original raw byte array if the class didn't need to be instrumented

Throws:

ClassNotFoundException - when an error occurs during the inspection or transformation
