Compiler

extends Object

java.lang.Object
↳	java.lang.Compiler

Class Overview

Placeholder class for environments which explicitly manage the action of a Just In Time (JIT) compiler. This class is usually implemented by the virtual machine vendor. The Android reference implementation does not (yet) contain such a JIT compiler, though other implementations may choose to provide one.

Summary

Public Methods
static Object	command(Object cmd) Executes an operation according to the specified command object.
static boolean	compileClass(Class<?> classToCompile) Compiles the specified class using the JIT compiler and indicates if compilation has been successful.
static boolean	compileClasses(String nameRoot) Compiles all classes whose name matches the specified name using the JIT compiler and indicates if compilation has been successful.
static void	disable() Disables the JIT compiler.
static void	enable() Enables the JIT compiler.

Inherited Methods

From class java.lang.Object

Object	clone() Creates and returns a copy of this `Object`.
boolean	equals(Object o) Compares this instance with the specified object and indicates if they are equal.
void	finalize() Is called before the object's memory is being reclaimed by the VM.
final Class<? extends Object>	getClass() Returns the unique instance of Class which represents this object's class.
int	hashCode() Returns an integer hash code for this object.
final void	notify() Causes a thread which is waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
final void	notifyAll() Causes all threads which are waiting on this object's monitor (by means of calling one of the `wait()` methods) to be woken up.
String	toString() Returns a string containing a concise, human-readable description of this object.
final void	wait(long millis, int nanos) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait(long millis) Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object or until the specified timeout expires.
final void	wait() Causes the calling thread to wait until another thread calls the `notify()` or `notifyAll()` method of this object.

Public Methods

public static Object command (Object cmd)

Executes an operation according to the specified command object. This method is the low-level interface to the JIT compiler. It may return any object or null if no JIT compiler is available.

Parameters

cmd	the command object for the JIT compiler.

Returns

the result of executing command or null.

public static boolean compileClass (Class<?> classToCompile)

Compiles the specified class using the JIT compiler and indicates if compilation has been successful.

Parameters

classToCompile	java.lang.Class the class to JIT compile

Returns

true if the compilation has been successful; false if it has failed or if there is no JIT compiler available.

public static boolean compileClasses (String nameRoot)

Compiles all classes whose name matches the specified name using the JIT compiler and indicates if compilation has been successful.

Parameters

nameRoot	the string to match class names with.

Returns

true if the compilation has been successful; false if it has failed or if there is no JIT compiler available.

public static void disable ()

Disables the JIT compiler.

public static void enable ()

Enables the JIT compiler.
