//Generator generator = CoreGenerator.getInstance().getGenerator(CoreGeneratorType.TOTAL);
//Generator generator = CoreGenerator.getInstance().getGenerator("BS");
//Generator generator = CoreGenerator.getInstance().getGenerator("ARCHIVE");
//Generator generator = CoreGenerator.getInstance().getGenerator("TOTAL");

//generate

generator.generate(oldFile, newFile, toGeneratedPatchFile);
//generator.generate(oldFile, newFile, toGeneratedPatchOutputStream);

//md5

String md5 = generator.calculateMD5(toGeneratedPatchFile);

Applier

//get applier

 Applier applier = CoreApplier.getInstance().getApplier(CoreApplierType.BS);
//Applier applier = CoreApplier.getInstance().getApplier(CoreApplierType.ARCHIVE);
//Applier applier = CoreApplier.getInstance().getApplier(CoreApplierType.TOTAL);
//Applier applier = CoreApplier.getInstance().getApplier("BS");
