Public Member Functions
virtual
ValueExtractor::View 		 getExtractor () const
  Retrieve the underlying ValueExtractor reference.
Returns:
the ValueExtractor
virtual
ValueUpdater::View 		 getUpdater () const
  Retrieve the underlying ValueUpdater reference.
Returns:
the ValueUpdater
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.

Returns:
a hash code value for this Object

Constructor & Destructor Documentation

PropertyManipulator ( String::View  vsName,
    bool  fUseIs = false  
  )     [protected]

Construct a PropertyManipulator for the specified property name.

This constructor assumes that the corresponding property getter will have a name of either ("get" + sName) or ("is + sName) and the corresponding property setter's name will be ("set + sName).

Parameters:
  vsName  a property name
  fUseIs  if true, the getter method will be prefixed with "is" rather than "get"
