Public Member Functions | |||||||
virtual bool | evaluateEntry (Map::Entry::View vEntry) const | ||||||
Apply the test to a Map::Entry and negate the result. | |||||||
virtual bool | evaluate (Object::View v) const | ||||||
Apply the test to the object and negate the result. | |||||||
virtual size32_t | calculateEffectiveness (Map::View vMapIndexes, Set::View vSetKeys) const | ||||||
Given a Map of available indexes, determine if this IndexAwareFilter can use any of the indexes to assist in its processing, and if so, determine how effective the use of that index would be. The returned value is an effectiveness estimate of how well this filter can use the specified indexes to filter the specified keys. An operation that requires no more than a single access to the index content (i.e. Equals, NotEquals) has an effectiveness of one. Evaluation of a single entry is assumed to have an effectiveness that depends on the index implementation and is usually measured as a constant number of the single operations. This number is referred to as evaluation cost.
If the effectiveness of a filter evaluates to a number larger than the

virtual Filter::View | applyIndex (Map::View vMapIndexes, Set::Handle hSetKeys) const | ||||||
Filter remaining keys using a Map of available indexes. The filter is responsible for removing all keys from the passed set of keys that the applicable indexes can prove should be filtered. If the filter does not fully evaluate the remaining keys using just the index information, it must return a filter (which may be an EntryFilter) that can complete the task using an iterating implementation. If, on the other hand, the filter does fully evaluate the remaining keys using just the index information, then it should return NULL to indicate that no further filtering is necessary.

virtual void | readExternal (PofReader::Handle hIn) | ||||||
Restore the contents of a user type instance by reading its state using the specified PofReader. | |||||||
virtual void | writeExternal (PofWriter::Handle hOut) const | ||||||
Save the contents of a POF user type instance by writing its state using the specified PofWriter. | |||||||
virtual bool | equals (Object::View v) const | ||||||
Compare the NotFilter with another object to determine equality. | |||||||
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.

Output a human-readable description of this Object to the given stream. | |||||||
virtual Filter::View | getFilter () const | ||||||
Obtain the Filter whose results are negated by this filter. | |||||||
Protected Member Functions | |||||||

Default constructor (necessary for the PortableObject interface). | |||||||
NotFilter (Filter::View hFilter) | |||||||
Create and return a Handle to a new Object instance. | |||||||
