public EnhancerImpl(EnhancementContext enhancementContext,
 ByteBuddyState byteBuddyState)

Constructs the Enhancer, using the given context.

Parameters:

enhancementContext - Describes the context in which enhancement will occur so as to give access to contextual/environmental information.

byteBuddyState - refers to the ByteBuddy instance to use

Parameters:

enhancementContext -

byteBuddyState -

classLocator -

Method Details

enhance

public byte[] enhance(String className,
 byte[] originalBytes)
               throws EnhancementException

Performs the enhancement.

Specified by:

enhance in interface Enhancer

Parameters:

className - The name of the class whose bytecode is being enhanced.

originalBytes - The class's original (pre-enhancement) byte code

Returns:

The enhanced bytecode. Could be the same as the original bytecode if the original was already enhanced or we could not enhance it for some reason.

Throws:

EnhancementException - Indicates a problem performing the enhancement

discoverTypes

public void discoverTypes(String className,
 byte[] originalBytes)

Description copied from interface: Enhancer

Discovers types prior to enhancement. It is possible to invoke this method concurrently.

Specified by:

discoverTypes in interface Enhancer

Parameters:

className - The name of the class whose bytecode is being analyzed for type discovery.

originalBytes - The class's original (pre-enhancement) byte code
