Detailed Description

Interface for searching database entries.

Search is based only on the information of one specific field of the entries. Using the interface for queries requires at first a QuickFilter() call and then a Filter() call.

filter()

virtual void Matcher::filter ( const CostDBEntryKey &  , CostDBTypes::EntryTable &    )

pure virtual

Searches for database entries that match the search key.

Implemented in ExactMatch, SelectSet< select, unSelect >, SelectSet<&EntryKeyField::isGreater, &EntryKeyField::isSmaller >, SelectSet<&EntryKeyField::isSmaller, &EntryKeyField::isGreater >, and Interpolation.

onlyThisFieldDiffers()

bool Matcher::onlyThisFieldDiffers ( const EntryKeyFieldProperty *  type, const CostDBEntry &  entry1, const CostDBEntry &  entry2  ) const

Checks if only a specific field of two entries is different and all other fields have equal values.

Parameters

type	Type of the field.
entry1	An entry.
entry2	An entry.

Returns

True if only one field of two entries is different, otherwise false.
