Public Member Functions | ||||
virtual Object::Holder | process (InvocableMap::Entry::Handle hEntry) const | |||
Process a Map::Entry object.
This implementation throws an UnsupportedOperationException.
| ||||
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 = cast<InvocableMap::Entry::Handle>(hIter->next()); hMapResults->put(hEntry->getKey(), process(hEntry)); } return hMapResults;

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
The default implementation is identity based.

Protected Member Functions | ||||
ConditionalPut () | ||||
Construct a ConditionalPut. | ||||
ConditionalPut (Filter::View vFilter, Object::Holder ohValue, bool fReturn=false) | ||||
Construct a ConditionalPut that updates an entry with a new value if and only if the filter applied to the entry evaluates to true. | ||||
Protected Attributes | ||||
FinalView< Filter > | f_vFilter | |||
The underlying filter. | ||||
FinalHolder< Object > | f_hValue | |||
Specifies the new value to update an entry with. | ||||
bool | m_fReturn | |||
Specifies whether or not a return value is required. |
ConditionalPut | ( | Filter::View | vFilter, | |
Object::Holder | ohValue, | |||
bool | fReturn = false | |||
) | [protected] |
Construct a ConditionalPut that updates an entry with a new value if and only if the filter applied to the entry evaluates to true.
This processor optionally returns the current value as a result of the invocation if it has not been updated (the filter evaluated to false).
