public abstract class AbstractProcessor<K,V,R>
extends Base
implements InvocableMap.EntryProcessor<K,V,R>

An AbstractProcessor is a partial EntryProcessor implementation that provides the default implementation of the processAll(java.util.Set<? extends com.tangosol.util.InvocableMap.Entry<K, V>>) method.

Method Detail

processAll

public Map<K,R> processAll(Set<? extends InvocableMap.Entry<K,V>> setEntries)

Process a Set of InvocableMap.Entry objects. This method is semantically equivalent to:

   Map mapResults = new ListMap();
   for (Iterator iter = setEntries.iterator(); iter.hasNext(); )
       {
       Entry entry = (Entry) iter.next();
       mapResults.put(entry.getKey(), process(entry));
       }
   return mapResults;
 

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.

Specified by:

processAll in interface InvocableMap.EntryProcessor<K,V,R>

Parameters:

setEntries - a Set of InvocableMap.Entry objects to process

Returns:

a Map containing the results of the processing, up to one entry for each InvocableMap.Entry that was processed, keyed by the keys of the Map that were processed, with a corresponding value being the result of the processing for each key
