Constructor Detail

Process

public Process(android.content.Context androidContext,
               java.lang.String uniqueID,
               int mediaAccessMask,
               Process.EventListener listener)

Creates a node.js process and attaches an event listener

Parameters:

androidContext - The current Android context.

uniqueID - A unique ID to identify the #Process across runs. The file system will be preserved and reused for all processes using the same ID.

mediaAccessMask - Permission mask for read/write access to external media.

listener - The listener interface object.

Method Detail

addEventListener

public void addEventListener(Process.EventListener listener)

Adds an EventListener to this Process

Parameters:

listener - the listener interface object

removeEventListener

public void removeEventListener(Process.EventListener listener)

Removes a listener from this Process

Parameters:

listener - the listener interface object to remove

isActive

public boolean isActive()

Determines if the process is currently active. If it is inactive, either it hasn't yet been started, or the process completed. Use an @EventListener to determine the state.

Returns:

true if active, false otherwise

exit

public void exit(int exitc)

Instructs the VM to halt execution as quickly as possible

Parameters:

exitc - The exit code

keepAlive

public JSContextGroup.LoopPreserver keepAlive()

Instructs the VM not to shutdown the process when no more callbacks are pending. In effect, this method indefinitely leaves a callback pending until the resulting #org.liquidplayer.javascript.JSContextGroup.LoopPreserver is released. The loop preserver must eventually be released or the process will remain active indefinitely.

Returns:

A preserver object

uninstall

public static void uninstall(android.content.Context ctx,
                             java.lang.String uniqueID,
                             Process.UninstallScope scope)

Uninstalls a given process class identified by its uniqueID

Parameters:

ctx - The Android context

uniqueID - The id of the process class

scope - scope in which to uninstall the process class
