public class ClassPool extends Object
This is a set of Clazz instances. They can be enumerated or retrieved by name. They can also be accessed by means of class visitors.

  • Constructor Details

    • ClassPool

      public ClassPool()
      Creates a new empty ClassPool.

    • ClassPool

      public ClassPool(Clazz... classes)
      Creates a new ClassPool with the given classes.
      Parameters:
      classes - the classes to be added.

    • ClassPool

      public ClassPool(Iterable<? extends Clazz> classes)
      Creates a new ClassPool with the given classes.
      Parameters:
      classes - the classes to be added.

    • ClassPool

      public ClassPool(ClassPool classPool)
      Creates a new ClassPool with the given classes. The keys are taken from the Clazz instances.
      Parameters:
      classPool - the classes to be added.

  • Method Details

    • clear

      public void clear()
      Clears the class pool.

    • addClass

      public void addClass(Clazz clazz)
      Adds the given Clazz to the class pool.

    • addClass

      public void addClass(String name, Clazz clazz)
      Adds the given Clazz with the given name to the class pool.

    • removeClass

      public void removeClass(Clazz clazz)
      Removes the given Clazz from the class pool.

    • removeClass

      public Clazz removeClass(String className)
      Removes the Class with the specified name from the class pool.

    • getClass

      public Clazz getClass(String className)
      Returns a Clazz from the class pool based on its name. Returns null if the class with the given name is not in the class pool.
      Parameters:
      className - a class name (e.g., "java/lang/String").
      Returns:
      the corresponding Clazz. null if the class pool does not contain a class with the specified name.

    • contains

      public boolean contains(Clazz clazz)
      Checks whether the given class exists in the class pool.

    • classNames

      public Iterator<String> classNames()
      Returns an Iterator of all class names in the class pool.

    • classes

      public Iterable<Clazz> classes()
      Returns an Iterable of all classes in the class pool.

    • size

      public int size()
      Returns the number of classes in the class pool.

    • refreshedCopy

      public ClassPool refreshedCopy()
      Returns a ClassPool with the same classes, but with the keys that correspond to the names of the class instances. This can be useful to create a class pool with obfuscated names.

    • refreshedKeysCopy

      public <T> Map<String,T> refreshedKeysCopy(Map<String,T> map)
      Returns a Map with the same contents as the given map, but with keys that have been mapped based from the names in the class pool to the names in the corresponding classes. This can be useful to create a map with obfuscated names as keys.

    • refreshedValuesCopy

      public <T> Map<T,String> refreshedValuesCopy(Map<T,String> map)
      Returns a Map with the same contents as the given map, but with values that have been mapped based from the names in the class pool to the names in the corresponding classes. This can be useful to create a map with obfuscated names as values.

    • reverseMapping

      public Map<Clazz,String> reverseMapping()
      Returns a Map that represents a mapping from every Clazz in the ClassPool to its original name. This can be useful to retrieve the original name of classes after name obfuscation has been applied.

    • accept

      public void accept(ClassPoolVisitor classPoolVisitor)
      Applies the given ClassPoolVisitor to the class pool.

    • classesAccept

      public void classesAccept(ClassVisitor classVisitor)
      Applies the given ClassVisitor to all classes in the class pool, in random order.

    • classesAcceptAlphabetically

      public void classesAcceptAlphabetically(ClassVisitor classVisitor)
      Applies the given ClassVisitor to all classes in the class pool, in sorted order.

    • classesAccept

      public void classesAccept(String classNameFilter, ClassVisitor classVisitor)
      Applies the given ClassVisitor to all matching classes in the class pool.

    • classesAccept

      public void classesAccept(List<String> classNameFilter, ClassVisitor classVisitor)
      Applies the given ClassVisitor to all matching classes in the class pool.

    • classesAccept

      public void classesAccept(StringMatcher classNameFilter, ClassVisitor classVisitor)
      Applies the given ClassVisitor to all matching classes in the class pool.

    • classAccept

      public void classAccept(String className, ClassVisitor classVisitor)
      Applies the given ClassVisitor to the class with the given name, if it is present in the class pool.
