Field Detail

RESOURCE_SYS_MEM_DEPLETED

public static final int RESOURCE_SYS_MEM_DEPLETED
Overall system memory is depleted to an implementation specific threshold. This indicates that the platform's application manager is about to destroy an application to free system memory.

Constant Field Values

RESOURCE_VM_MEM_DEPLETED

public static final int RESOURCE_VM_MEM_DEPLETED
VM memory for an application is depleted to an implementation specific threshold. This indicates that the platform's application manager is about to destroy an application to free VM memory.

See Also:
Constant Field Values

RESOURCE_CPU_BANDWIDTH_DEPLETED

public static final int RESOURCE_CPU_BANDWIDTH_DEPLETED
Available CPU cycles is depleted to an implementation specific threshold. This indicates that the platform's application manager is about to destroy an application to free CPU cycles.

Note that the presence of this event type does not imply that the platform's application manager must destroy applications if CPU usage is too high; merely that if it does then it must first send this event.

See Also:
Constant Field Values

RESOURCE_RC_BANDWIDTH_DEPLETED

public static final int RESOURCE_RC_BANDWIDTH_DEPLETED
Available reverse channel bandwidth is depleted to implementation specific threshold. This indicates that the platform's application manager is about to destroy an application to free return channel bandwidth.

Note that the presence of this event type does not imply that the platform's application manager must destroy applications if return channel bandwidth usage is too high; merely that if it does then it must first send this event.

Constructor Detail

ResourceDepletionEvent

public ResourceDepletionEvent(int typeCode,
                              java.lang.String message)
System event constructor assigns an eventId, Date, and ApplicationIdentifier.

Parameters:
typeCode - - Unique event type.
message - - Readable message specific to the event generator.
Throws:
java.lang.IllegalArgumentException - if the typeCode is not in a defined application range when the event is created by an application. Since there are no defined application ranges for resource depletion events, this exception will always be thrown if this constructor is called by an application.

ResourceDepletionEvent

public ResourceDepletionEvent(int typeCode,
                              java.lang.String message,
                              long date,
                              AppID appId)
This constructor is provided for internal use by OCAP implementations; applications SHOULD NOT call it.

Parameters:
typeCode - - The unique error type code.
message - - Readable message specific to the event generator.
date - - Event date in milli-seconds from midnight January 1, 1970 GMT.
appId - - The Id of the application logging the event.
Throws:
java.lang.SecurityException - if this constructor is called by any application.
