    31  * Class provides common access to CRemConInterfaceSelector for Java components

    32  *

    33  * Java RunTime needs to listen to various events like volume key press,

    34  * media key press and so on. For this purpose, various modules

    35  * in Java middleware register with CRemConCoreApiTarget to get events

    36  * to the observer MRemConCoreApiTargetObserver.

    37  * For this to happen, a target session has to be opened to RemCon,

    38  * which is done via CRemConInterfaceSelector::OpenTargetL(). At present,

    39  * whichever module wants it (say MMAPI, LCDUI etc) goes ahead and registers

    40  * by calling CRemConInterfaceSelector::OpenTargetL(). However when someother

    41  * module also calls the same, the OpenTargetL() returns KErrInUse as in

    42  * Java all modules are in one single process and one process can have

    43  * only one target session open to RemCon. This means that only one of the

    44  * required modules will get the events needed.

    45  *

    46  * Class provides common access to the target session to RemCon

    47  * which can be used by any module in Java.

    48  * The user of CRemConCoreApiTarget will need to use this class for the purpose

    49  * instead of creating themselves.
