Public methods

command

Added in API level 1

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

Added in API level 1

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

Added in API level 1

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

Added in API level 1

public static void disable ()

Disables the JIT compiler. Does nothing on Android.

enable

Added in API level 1

public static void enable ()

Enables the JIT compiler. Does nothing on Android.
