Method Details

type

public Type type()

Returns . the type of the class being transformed

Specified by:

type in interface SimpleTransformationContext

Returns:

node

public org.objectweb.asm.tree.ClassNode node()

Returns the class being transformed. Modifications will be reflected in the output bytecode (and the loaded class).

Returns:

the class being transformed

empty

public boolean empty()

Returns whether the class was empty when provided to this transformer. Note that a class might not exist on disk but still return false here, if an earlier transformer provided it.

Specified by:

empty in interface SimpleTransformationContext

Returns:

whether the class was empty when provided to this transformer

audit

public void audit(String activity,
 String... context)

Add audit activity for this transformation.

Parameters:

activity - what was done to the class

context - any additional information to include

initialSha256

public byte[] initialSha256()

Returns the SHA-256 hash of the original class bytecode.

Specified by:

initialSha256 in interface SimpleTransformationContext

Returns:

the SHA-256 hash of the original class bytecode
