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:

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 void 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 @letDie() is called. This must be followed up by a call to letDie() or the process will remain active indefinitely.

letDie

public void letDie()

Instructs the VM to not keep itself alive if no more callbacks are pending.

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
