Inherits AbstractProcessor, and PortableObject.

List of all members.

Detailed Description

Conditional entry processor represents a processor that is invoked conditionally based on the result of an entry evaluation.

Public Types

typedef spec::Handle Handle
 ConditionalProcessor Handle definition.
typedef spec::View View
 ConditionalProcessor View definition.
typedef spec::Holder Holder
 ConditionalProcessor Holder definition.

Public Member Functions

virtual Object::Holder process (InvocableMap::Entry::Handle hEntry) const
 Process a Map::Entry object.

hEntry the Entry to process
the result of the processing, if any

virtual Map::View processAll (Set::View vsetEntries) const
 Process a Set of InvocableMap::Entry objects.

This method is semantically equivalent to:

   Map::Handle hMapResults = HashMap::create();
   for (Iterator::Handle hIter = vSetEntries->iterator();
       iter->hasNext; )
       InvocableMap::Entry::Handle hEntry =
       hMapResults->put(hEntry->getKey(), process(hEntry));
   return hMapResults;

vSetEntries a Set of InvocableMap::Entry objects to process
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

virtual void readExternal (PofReader::Handle hIn)
virtual void writeExternal (PofWriter::Handle hOut) const
virtual bool equals (Object::View v) const
virtual size32_t hashCode () const
 Return a hash code value for the Object.

This method is supported for the benefit of hash-based containers.

The general contract of hashCode is:

  • Whenever it is invoked on the same Object more than once during an execution of an application, the hashCode method must consistently return the same value, provided no information used in equals comparisons on the object is modified. This value need not remain consistent from one execution of an application to another execution of the same application.
  • If two Objects are equal according to the equals method, then calling the hashCode method on each of the two Objects must produce the same value.
  • It is not required that if two Objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct results. However, the programmer should be aware that producing distinct results for unequal objects may improve the performance of hash-based containers.

The default implementation is identity based.

Protected Member Functions

 ConditionalProcessor ()
 Construct a ConditionalProcessor.
 ConditionalProcessor (Filter::View vFilter, InvocableMap::EntryProcessor::View vProcessor)
 Construct a ConditionalProcessor for the specified filter and the processor.

Protected Attributes

FinalView< Filterf_vFilter
 The underlying filter.
< InvocableMap::EntryProcessor
 The underlying entry processor.

Constructor & Destructor Documentation

ConditionalProcessor ( Filter::View  vFilter,
InvocableMap::EntryProcessor::View  vProcessor 
) [protected]

Construct a ConditionalProcessor for the specified filter and the processor.

The specified entry processor gets invoked if and only if the filter applied to the InvocableMap entry evaluates to true; otherwise the result of the process invocation will return NULL.

vFilter the filter
vProcessor the entry processor
