Detailed Description

template<class K, class FCP, class ORDER>
class CdbBdbSAbsBtreeItr< K, FCP, ORDER >

The internal implementation for the public iterator for B-tree keys.

This class provides the actual implementation of the B-tree browsing. This class has the same template parameters as the B-tree class.

DESIGN & IMPLEMENTATION NOTE:

Due to current design of the abstract B-tree class the current iterator's interface is type-intrusive. This may be solved later.

Member Typedef Documentation

template<class K, class FCP, class ORDER> typedef CdbIItr<K>::InterfaceType CdbBdbSAbsBtreeItr< K, FCP, ORDER >::InterfaceType

This is a type of a base iterator interface Reimplemented from CdbIItr< K >. Definition at line 39 of file CdbBdbSAbsBtreeItr.hh.

template<class K, class FCP, class ORDER> typedef CdbIItr<K>::ValueType CdbBdbSAbsBtreeItr< K, FCP, ORDER >::ValueType

Introduce a type definition for the purpose of easier reference. This definition provides access to the type of the parameter used for the concrete template instantiation. Reimplemented from CdbIItr< K >. Definition at line 38 of file CdbBdbSAbsBtreeItr.hh.

Constructor & Destructor Documentation

template<class K, class FCP, class ORDER> CdbBdbSAbsBtreeItr< K, FCP, ORDER >::CdbBdbSAbsBtreeItr (  const CdbBdbSAbsBtreeItr< K, FCP, ORDER > &    theItr )  [protected]

The copy constructor. The only reason why we have it implemented is because it's needed to implement the clone method. See also: CdbBdbSAbsBtreeItr::clone() Definition at line 33 of file CdbBdbSAbsBtreeItr.cc.

template<class K, class FCP, class ORDER> CdbBdbSAbsBtreeItr< K, FCP, ORDER >::CdbBdbSAbsBtreeItr (  const CdbBdbSAbsBtree< K, FCP, ORDER > *    theTree )

The normal constructor. Non 0 pointer is expected. Definition at line 22 of file CdbBdbSAbsBtreeItr.cc.

template<class K, class FCP, class ORDER> CdbBdbSAbsBtreeItr< K, FCP, ORDER >::~CdbBdbSAbsBtreeItr (    )  [virtual]

The destructor. Details... Definition at line 45 of file CdbBdbSAbsBtreeItr.cc.

Member Function Documentation

template<class K, class FCP, class ORDER> CdbBdbSAbsBtreeItr< K, FCP, ORDER >::InterfaceType * CdbBdbSAbsBtreeItr< K, FCP, ORDER >::clone (    )  const [virtual]

Make a clone of itself. See also: CdbIItr::clone() Implements CdbIItr< K >. Definition at line 227 of file CdbBdbSAbsBtreeItr.cc.

template<class K, class FCP, class ORDER> bool CdbBdbSAbsBtreeItr< K, FCP, ORDER >::isValid (    )  [virtual]

Check if an iterator is valid. This implements the corresponding method of the base class. See also: CdbIItr::isValid() Implements CdbIItr< K >. Definition at line 218 of file CdbBdbSAbsBtreeItr.cc.

template<class K, class FCP, class ORDER> bool CdbBdbSAbsBtreeItr< K, FCP, ORDER >::next (    )  [virtual]

Advance an iterator to the next position. This implements the corresponding method of the base class. See also: CdbIItr::next() Implements CdbIItr< K >. Definition at line 120 of file CdbBdbSAbsBtreeItr.cc.

template<class K, class FCP, class ORDER> CdbStatus CdbBdbSAbsBtreeItr< K, FCP, ORDER >::reset (    )  [virtual]

Reset an iterator to its initial state. This implements the corresponding method of the base class. See also: CdbIItr::reset CdbStatus Implements CdbIItr< K >. Definition at line 52 of file CdbBdbSAbsBtreeItr.cc. References CdbStatus::Success.

template<class K, class FCP, class ORDER> CdbBdbSAbsBtreeItr< K, FCP, ORDER >::ValueType CdbBdbSAbsBtreeItr< K, FCP, ORDER >::value (    )  [virtual]

Obtain the currently reffered value. This implements the corresponding method of the base class. See also: CdbIItr::value() CdbIItr::ValueType Returns: the current value the iterator is set on Implements CdbIItr< K >. Definition at line 207 of file CdbBdbSAbsBtreeItr.cc.
