The library differentiates between two different main modes: Bytecode and Sourcecode where each provides its unique set of transformers. For instance:
Path source = ...;
Path target = ...;
AccessMapping mapping = ...;
Plunger plunger = BytecodePlunger.builder()
.withTransformer(new AccessMappingBytecodeTransformer(mapping))
.build(source, target);
// or
Plunger plunger = SourcecodePlunger.builder()
.withTransformer(new AccessMappingSourcecodeTransformer(mapping))
.build(source, target);
// both provide:
plunger.apply();
Note that the source and target paths may be located in any type of NIO filesystem (including the jar file system). For your convenience, Plunger includes the factory methods Plunger#openZipArchive(Path) and Plunger#createZipArchive(Path).
