Syntax

public class PreloadRequest : AbstractProcessor, IEntryProcessor, IPortableObject

Remarks

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's 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 IEntryProcessor has no effect.
