Constructor Detail

CardRemoteObject

public CardRemoteObject()
Creates a new CardRemoteObject and automatically exports it. When exported, the object is enabled for remote access from outside the card until unexported. Only when the object is enabled for remote access can it be returned as the initial reference during selection or returned by a remote method. In addition, remote methods can be invoked only on objects enabled for remote access.

Method Detail

export

public static void export(Remote obj)
                   throws SecurityException
Exports the specified remote object. The object is now enabled for remote access from outside the card until unexported. In order to remotely access the remote object from the terminal client, it must either be set as the initial reference or be returned by a remote method.

Parameters:
obj - the remotely accessible object
Throws:
SecurityException - if the specified obj parameter is not owned by the caller context
SystemException - with the following reason codes:
  • SystemException.NO_RESOURCE if too many exported remote objects. All implementations must support a minimum of 16 exported remote objects.

unexport

public static void unexport(Remote obj)
                     throws SecurityException
Unexports the specified remote object. After applying this method, the object cannot be remotely accessed from outside the card until it is exported again.

Note:

Parameters:
obj - the remotely accessible object
Throws:
SecurityException - if the specified obj parameter is not owned by the caller context
