Class ClassObfuscator

java.lang.Object

proguard.obfuscate.ClassObfuscator

All Implemented Interfaces:

proguard.classfile.attribute.visitor.AttributeVisitor, proguard.classfile.attribute.visitor.InnerClassesInfoVisitor, proguard.classfile.constant.visitor.ConstantVisitor, proguard.classfile.visitor.ClassVisitor

public class ClassObfuscator
extends java.lang.Object
implements proguard.classfile.visitor.ClassVisitor, proguard.classfile.attribute.visitor.AttributeVisitor, proguard.classfile.attribute.visitor.InnerClassesInfoVisitor, proguard.classfile.constant.visitor.ConstantVisitor

This ClassVisitor comes up with obfuscated names for the classes it visits, and for their class members. The actual renaming is done afterward.

Constructor Detail

ClassObfuscator

public ClassObfuscator(proguard.classfile.ClassPool programClassPool,
                       proguard.classfile.ClassPool libraryClassPool,
                       DictionaryNameFactory classNameFactory,
                       DictionaryNameFactory packageNameFactory,
                       boolean useMixedCaseClassNames,
                       java.util.List keepPackageNames,
                       java.lang.String flattenPackageHierarchy,

                       boolean allowAccessModification,
                       boolean adaptKotlin)

Creates a new ClassObfuscator.

Parameters:

programClassPool - the class pool in which class names have to be unique.

libraryClassPool - the class pool from which class names have to be avoided.

classNameFactory - the optional class obfuscation dictionary.

packageNameFactory - the optional package obfuscation dictionary.

useMixedCaseClassNames - specifies whether obfuscated packages and classes can get mixed-case names.

keepPackageNames - the optional filter for which matching package names are kept.

flattenPackageHierarchy - the base package if the obfuscated package hierarchy is to be flattened.

repackageClasses - the base package if the obfuscated classes are to be repackaged.

allowAccessModification - specifies whether obfuscated classes can be freely moved between packages.

adaptKotlin - specifies whether Kotlin should be supported.
