Public Member Functions | ||||
virtual bool | evaluate (Object::View v) const | |||
Apply the test to the object.
| ||||
virtual MapEvent::Handle | transform (MapEvent::Handle hEvent) const | |||
Transform the specified MapEvent. The values contained by the returned MapEvent object will be the ones given (sent) to the corresponding listener.
| ||||
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
The default implementation is identity based.
| ||||
virtual TypedHandle < const String > | toString () const | |||
Output a human-readable description of this Object to the given stream. Note that when overriding this method the return type must be TypedHandle<const String> rather then String::View. These two types are assignment compatible but not equivalent and declaring the override with String::View will not be a compatible override. coherence::lang::operator<<(std::ostream, Object::View) is defined and will call into the toString method, to output Objects. If a managed String object is desired, the COH_TO_STRING macro can be used to build up a String from streamable contents and is generally how toString() will be implemented.
Object::View vKey = ... Object::View vValue = ... std::cout << vKey << " = " << vValue << std::endl; String::View vs = COH_TO_STRING(vKey << " = " << vValue); The COH_TO_STRING macro is also the most common way to implement the toString method. For example:
virtual TypedHandle<const String> Person::toString() const { return COH_TO_STRING("Name: " << f_sName << " SSN: " << f_nSSN); }

Protected Member Functions | ||||
MapEventTransformerFilter () | ||||
Default constructor (necessary for the PortableObject interface). | ||||
MapEventTransformerFilter (Filter::View vFilter, MapEventTransformer::View vTransformer) | ||||
Construct a MapEventTransformerFilter based on the specified Filter and MapEventTransformer. |
MapEventTransformerFilter | ( | Filter::View | vFilter, | |
MapEventTransformer::View | vTransformer | |||
) | [protected] |
Construct a MapEventTransformerFilter based on the specified Filter and MapEventTransformer.
vFilter | the underlying Filter (e.g. MapEventFilter) used to evaluate original MapEvent objects (optional) | |
vTransformer | the underlying MapEventTransformer used to transform original MapEvent objects |
