java.lang.Error

javax.realtime.StaticError

javax.realtime.MemoryAccessError

All Implemented Interfaces:

java.io.Serializable, StaticThrowable<MemoryAccessError>

public class MemoryAccessError
extends StaticError
implements StaticThrowable<MemoryAccessError>

This error is thrown on an attempt to refer to an object in an inaccessible MemoryArea. For example, when logic in a RealtimeThread or AsyncBaseEventHandler configured with a javax.realtime.memory.ScopedConfigurationParameters object, attempts to refer to an object in a HeapMemory area.

Since:

RTSJ 2.0 extends StaticError
