Member Function Documentation

virtual int dsHashTableGeneric::cf (  void *    a, void *    b )  [protected, pure virtual]

Implemented in dsHashTable.

void dsHashTableGeneric::clear (    )

Reinit table, keep current size

int dsHashTableGeneric::HSize (  void    )  [inline]

Function returns curren table size

void * dsHashTableGeneric::insert (  void *    a, bool    replace = false )  [virtual]

Insert object a into data storage, if replace flag is set existing object will be replaced. Return pointer to existsing object or NULL if new object was inserted. Implements dsDataAccessor.

int dsHashTableGeneric::NumEntries (  void    )  [inline]

Function returns number of non-empty records in the table

virtual int dsHashTableGeneric::primary_hash_func (  void *    a )  [protected, pure virtual]

Implemented in dsHashTable.

void * dsHashTableGeneric::remove (  void *    a )  [virtual]

Remove object a from data storage. Return pointer to removed object or NULL if object doesn't exist Implements dsDataAccessor.

virtual int dsHashTableGeneric::secondary_hash_func (  void *    a )  [protected, pure virtual]

Implemented in dsHashTable.

void * dsHashTableGeneric::seek (  void *    a )  [virtual]

Find object matching a in tree and return pointer to found one or NULL if seek can't be done. Implements dsDataAccessor.

virtual void* dsDataAccessor::walk (    )  [inline, protected, virtual, inherited]

Walk throuph storage behavioure details depends of storage nature

void * dsHashTableGeneric::walk (  int    i )  [inline]

Function returns table i'th table record even it is empty
