All Known Implementing Classes:

Enclosing interface:

InvocableMap

public static interface InvocableMap.EntryProcessor

extends java.io.Serializable

An invocable agent that operates against the Entry objects within a Map.

Method Summary

java.lang.Object	process(InvocableMap.Entry entry) Process a Map.Entry object.
java.util.Map	processAll(java.util.Set setEntries) Process a Set of InvocableMap.Entry objects.

Method Detail

process

java.lang.Object process(InvocableMap.Entry entry)

Process a Map.Entry object.

Parameters:

entry - the Entry to process

Returns:

the result of the processing, if any

processAll

java.util.Map processAll(java.util.Set 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, entries that were removed from the setEntries would be considered successfully processed and corresponding changes will be made to the underlying Map.

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
