ClassPool (Javassist API)

java.lang.Object
- javassist.ClassPool

```
public class ClassPool
extends java.lang.Object
```
A container of CtClass objects. A CtClass object must be obtained from this object. If get() is called on this object, it searches various sources represented by ClassPath to find a class file and then it creates a CtClass object representing that class file. The created object is returned to the caller.
Memory consumption memo:
ClassPool objects hold all the CtClasses that have been created so that the consistency among modified classes can be guaranteed. Thus if a large number of CtClasses are processed, the ClassPool will consume a huge amount of memory. To avoid this, a ClassPool object should be recreated, for example, every hundred classes processed. Note that getDefault() is a singleton factory. Otherwise, detach() in CtClass should be used to avoid huge memory consumption.
ClassPool hierarchy:
ClassPools can make a parent-child hierarchy as java.lang.ClassLoaders. If a ClassPool has a parent pool, get() first asks the parent pool to find a class file. Only if the parent could not find the class file, get() searches the ClassPaths of the child ClassPool. This search order is reversed if ClassPath.childFirstLookup is true.

- Field Detail
  - childFirstLookup
```
public boolean childFirstLookup
```
    Determines the search order.
    If this field is true, get() first searches the class path associated to this ClassPool and then the class path associated with the parent ClassPool. Otherwise, the class path associated with the parent is searched first.
    The default value is false.
  - doPruning
```
public static boolean doPruning
```
    Turning the automatic pruning on/off.
    If this field is true, CtClass objects are automatically pruned by default when toBytecode() etc. are called. The automatic pruning can be turned on/off individually for each CtClass object.
    The initial value is false.
    
    See Also:
    
    CtClass.prune(), CtClass.stopPruning(boolean), CtClass.detach()
  - releaseUnmodifiedClassFile
```
public static boolean releaseUnmodifiedClassFile
```
    If true, unmodified and not-recently-used class files are periodically released for saving memory.
    The initial value is true.
- Constructor Detail
  - ClassPool
```
public ClassPool()
```
    Creates a root class pool. No parent class pool is specified.
  - ClassPool
```
public ClassPool(boolean useDefaultPath)
```
    Creates a root class pool. If useDefaultPath is true, appendSystemPath() is called. Otherwise, this constructor is equivalent to the constructor taking no parameter.
    
    Parameters:
    
    useDefaultPath - true if the system search path is appended.
  - ClassPool
```
public ClassPool(ClassPool parent)
```
    Creates a class pool.
    
    Parameters:
    
    parent - the parent of this class pool. If this is a root class pool, this parameter must be null.
    
    See Also:
    
    getDefault()
- Method Detail
  - getDefault
```
public static ClassPool getDefault()
```
    Returns the default class pool. The returned object is always identical since this method is a singleton factory.
    The default class pool searches the system search path, which usually includes the platform library, extension libraries, and the search path specified by the -classpath option or the CLASSPATH environment variable.
    When this method is called for the first time, the default class pool is created with the following code snippet:
```
ClassPool cp = new ClassPool();
 cp.appendSystemPath();
 
```
    If the default class pool cannot find any class files, try ClassClassPath and LoaderClassPath.
    See Also:
    
    ClassClassPath, LoaderClassPath
  - toString
```
public java.lang.String toString()
```
    Returns the class search path.
    
    Overrides:
    
    toString in class java.lang.Object
  - importPackage
```
public void importPackage(java.lang.String packageName)
```
    Record a package name so that the Javassist compiler searches the package to resolve a class name. Don't record the java.lang package, which has been implicitly recorded by default.
    Since version 3.14, packageName can be a fully-qualified class name.
    Note that get() in ClassPool does not search the recorded package. Only the compiler searches it.
    
    Parameters:
    
    packageName - the package name. It must not include the last '.' (dot). For example, "java.util" is valid but "java.util." is wrong.
    
    Since:
    
    3.1
  - clearImportedPackages
```
public void clearImportedPackages()
```
    Clear all the package names recorded by importPackage(). The java.lang package is not removed.
    
    Since:
    
    3.1
    
    See Also:
    
    importPackage(String)
  - getImportedPackages
```
public java.util.Iterator getImportedPackages()
```
    Returns all the package names recorded by importPackage().
    
    Since:
    
    3.1
    
    See Also:
    
    importPackage(String)
  - recordInvalidClassName
```
public void recordInvalidClassName(java.lang.String name)
```
    Deprecated.
    
    Records a class name that never exists. For example, a package name can be recorded by this method. This would improve execution performance since get() quickly throw an exception without searching the class path at all if the given name is an invalid name recorded by this method. Note that searching the class path takes relatively long time.
    The current implementation of this method performs nothing.
    
    Parameters:
    
    name - an invalid class name (separeted by dots).
  - lookupCflow
```
public java.lang.Object[] lookupCflow(java.lang.String name)
```
    Undocumented method. Do not use; internal-use only.
    
    Parameters:
    
    name - the name of $cflow variable
  - getAndRename
```
public CtClass getAndRename(java.lang.String orgName,
                            java.lang.String newName)
                     throws NotFoundException
```
    Reads a class file and constructs a CtClass object with a new name. This method is useful if you want to generate a new class as a copy of another class (except the class name). For example,
```
 getAndRename("Point", "Pair")
 
```
    returns a CtClass object representing Pair class. The definition of Pair is the same as that of Point class except the class name since Pair is defined by reading Point.class.
    Parameters:
    
    orgName - the original (fully-qualified) class name
    
    newName - the new class name
    
    Throws:
    
    NotFoundException
  - get
```
public CtClass get(java.lang.String classname)
            throws NotFoundException
```
    Reads a class file from the source and returns a reference to the CtClass object representing that class file. If that class file has been already read, this method returns a reference to the CtClass created when that class file was read at the first time.
    If classname ends with "[]", then this method returns a CtClass object for that array type.
    To obtain an inner class, use "$" instead of "." for separating the enclosing class name and the inner class name.
    
    Parameters:
    
    classname - a fully-qualified class name.
    
    Throws:
    
    NotFoundException
  - getOrNull
```
public CtClass getOrNull(java.lang.String classname)
```
    Reads a class file from the source and returns a reference to the CtClass object representing that class file. This method is equivalent to get except that it returns null when a class file is not found and it never throws an exception.
    
    Parameters:
    
    classname - a fully-qualified class name.
    
    Returns:
    
    a CtClass object or null.
    
    Since:
    
    3.13

  - getCtClass
```
public CtClass getCtClass(java.lang.String classname)
                   throws NotFoundException
```
    Returns a CtClass object with the given name. This is almost equivalent to get(String) except that classname can be an array-type "descriptor" (an encoded type name) such as [Ljava/lang/Object;.
    Using this method is not recommended; this method should be used only to obtain the CtClass object with a name returned from getClassInfo in javassist.bytecode.ClassPool. getClassInfo returns a fully-qualified class name but, if the class is an array type, it returns a descriptor.
    
    Parameters:
    
    classname - a fully-qualified class name or a descriptor representing an array type.
    
    Throws:
    
    NotFoundException

  - find
```
public java.net.URL find(java.lang.String classname)
```
    Searches the class path to obtain the URL of the class file specified by classname. It is also used to determine whether the class file exists.
    
    Parameters:
    
    classname - a fully-qualified class name.
    
    Returns:
    
    null if the class file could not be found.

```
public CtClass[] get(java.lang.String[] classnames)
              throws NotFoundException
```
    Reads class files from the source and returns an array of CtClass objects representing those class files.
    If an element of classnames ends with "[]", then this method returns a CtClass object for that array type.
    
    Parameters:
    
    classnames - an array of fully-qualified class name.
    
    Throws:

    Converts the given class to a java.lang.Class object. Once this method is called, further modifications are not allowed any more. To load the class, this method uses the context class loader of the current thread. It is obtained by calling getClassLoader().
    This behavior can be changed by subclassing the pool and changing the getClassLoader() method. If the program is running on some application server, the context class loader might be inappropriate to load the class.
    This method is provided for convenience. If you need more complex functionality, you should write your own class loader.
    Warining: A Class object returned by this method may not work with a security manager or a signed jar file because a protection domain is not specified.
    
    Throws:
    
    CannotCompileException

public java.lang.ClassLoader getClassLoader()
```
    Get the classloader for toClass(), getAnnotations() in CtClass, etc.
    The default is the context class loader.
    
    Returns:
    
    the classloader for the pool

    Deprecated. Replaced by toClass(CtClass,ClassLoader,ProtectionDomain). A subclass of ClassPool that has been overriding this method should be modified. It should override toClass(CtClass,ClassLoader,ProtectionDomain).
    
    Converts the class to a java.lang.Class object. Do not override this method any more at a subclass because toClass(CtClass) never calls this method.
    Warining: A Class object returned by this method may not work with a security manager or a signed jar file because a protection domain is not specified.

```
public java.lang.Class toClass(CtClass ct,
                               java.lang.ClassLoader loader,
                               java.security.ProtectionDomain domain)
                        throws CannotCompileException
```
    Converts the class to a java.lang.Class object. Once this method is called, further modifications are not allowed any more.
    The class file represented by the given CtClass is loaded by the given class loader to construct a java.lang.Class object. Since a private method on the class loader is invoked through the reflection API, the caller must have permissions to do that.
    An easy way to obtain ProtectionDomain object is to call getProtectionDomain() in java.lang.Class. It returns the domain that the class belongs to.
    This method is provided for convenience. If you need more complex functionality, you should write your own class loader.
    
    Parameters:
    
    loader - the class loader used to load this class. For example, the loader returned by getClassLoader() can be used for this parameter.
    
    domain - the protection domain for the class. If it is null, the default domain created by java.lang.ClassLoader is used.
    
    Throws:
    
    CannotCompileException
    
    Since:
    
    3.3

```
    Defines a new package. If the package is already defined, this method performs nothing.
    You do not necessarily need to call this method. If this method is called, then getPackage() on the Class object returned by toClass() will return a non-null object.
    
    Parameters:
    
    loader - the class loader passed to toClass() or the default one obtained by getClassLoader().
    
    name - the package name.
    
    Throws:
    
    CannotCompileException
