Class MemoryTrustedLocator

java.lang.Object

de.intarsys.tools.locator.trusted.TrustedLocator

de.intarsys.tools.locator.trusted.MemoryTrustedLocator

All Implemented Interfaces:

IAdapterSupport, ISynchronizable, ILocator, ITrustedLocator

public class MemoryTrustedLocator
extends TrustedLocator

This ILocator controls manipulation of its data resource simply by copying it completely to memory. All I/O is done through the in memory buffer. When it comes to writing the data, the buffer is always completely written back.

This locator acts on a "committed read" concurrency strategy. If an output stream or random access is open, other clients requesting stream will always see the old state until the output stream or random access will flush. From now the changes are visible to NEW stream, but still not to the old ones.
