+/**
+ * Class provides common access to CRemConInterfaceSelector for Java components
+ *
+ * Java RunTime needs to listen to various events like volume key press,
+ * media key press and so on. For this purpose, various modules
+ * in Java middleware register with CRemConCoreApiTarget to get events
+ * to the observer MRemConCoreApiTargetObserver.
+ * For this to happen, a target session has to be opened to RemCon,
+ * which is done via CRemConInterfaceSelector::OpenTargetL(). At present,
+ * whichever module wants it (say MMAPI, LCDUI etc) goes ahead and registers
+ * by calling CRemConInterfaceSelector::OpenTargetL(). However when someother
+ * module also calls the same, the OpenTargetL() returns KErrInUse as in
+ * Java all modules are in one single process and one process can have
+ * only one target session open to RemCon. This means that only one of the
+ * required modules will get the events needed.
+ *
+ * Class provides common access to the target session to RemCon
+ * which can be used by any module in Java.
+ * The user of CRemConCoreApiTarget will need to use this class for the purpose
+ * instead of creating themselves.
