From class java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.

`final void`	`wait(long timeoutMillis, int nanos)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait(long timeoutMillis)` Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
`final void`	`wait()` Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

Public methods

command

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. Returns null on Android, whether or not the system has a JIT.

Parameters
`cmd`	`Object`: the command object for the JIT compiler.

Returns
`Object`	the result of executing command or `null`.

compileClass

public static boolean compileClass (Class<?> classToCompile)

Compiles the specified class using the JIT compiler and indicates if compilation has been successful. Does nothing and returns false on Android.

Parameters
`classToCompile`	`Class`: java.lang.Class the class to JIT compile

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

compileClasses

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. Does nothing and returns false on Android.

Parameters
`nameRoot`	`String`: the string to match class names with.

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

disable

public static void disable ()

Disables the JIT compiler. Does nothing on Android.

enable

public static void enable ()

Enables the JIT compiler. Does nothing on Android.
