public class PreloadRequest<K,V> extends AbstractProcessor<K,V,V> implements ExternalizableLite, PortableObject
Entry.getValue call. No results are reported back to the caller.
The PreloadRequest process provides a means to "pre-load" an entry or a collection of entries into the cache using the cache loader without incurring the cost of sending the value(s) over the network. If the corresponding entry (or entries) already exists in the cache, or if the cache does not have a loader, then invoking this EntryProcessor has no effect.

Note: if this method throws an exception, all modifications to the supplied entry or any other entries retrieved via the BackingMapContext.getBackingMapEntry(java.lang.Object) API will be rolled back leaving all underlying values unchanged.

Note: if processAll() call throws an exception, only the entries that were removed from the setEntries would be considered successfully processed and the corresponding changes made to the underlying Map; changes made to the remaining entries or any other entries obtained from BackingMapContext.getBackingMapEntry(java.lang.Object) will not be processed. Note: As of Coherence 12.2.1, this method simply delegates to the default processAll implementation in InvocableMap.EntryProcessor.
