Detailed Description

This class is used by match units to create instances of the appropriate LookupStructure implementation. In order to use custom data structures in a target, the data structures should be defined, and then a new subclass of LookupStructureFactory should be created, overriding the create_for_<match type> function or functions corresponding to the new data structure.

create()

template<typename K >

static std::unique_ptr<LookupStructure<K> > bm::LookupStructureFactory::create ( LookupStructureFactory *  f, size_t  size, size_t  nbytes_key  )

static

This is a utility to call the correct create_for_<type> function based on the bm::MatchKey subtype passed as the template parameter K. This is used by bm::MatchUnitGeneric when creating its lookup structure.

create_for_exact()

virtual std::unique_ptr<ExactLookupStructure> bm::LookupStructureFactory::create_for_exact ( size_t  size, size_t  nbytes_key  )

virtual

Create a lookup structure for exact matches.

create_for_LPM()

virtual std::unique_ptr<LPMLookupStructure> bm::LookupStructureFactory::create_for_LPM ( size_t  size, size_t  nbytes_key  )

virtual

Create a lookup structure for LPM matches.

create_for_range()

virtual std::unique_ptr<RangeLookupStructure> bm::LookupStructureFactory::create_for_range ( size_t  size, size_t  nbytes_key  )

virtual

Create a lookup structure for range macthes.

create_for_ternary()

virtual std::unique_ptr<TernaryLookupStructure> bm::LookupStructureFactory::create_for_ternary ( size_t  size, size_t  nbytes_key  )

virtual

Create a lookup structure for ternary matches.
