Member Function Documentation

BeginRead()

template<class T >

virtual size_t Arp::System::Rsc::Services::IRscReadEnumerator< T >::BeginRead ( void  )

pure virtual

Begins the operation to read the enumerator.

Returns

Number of elements for array enumerators. UndefinedArrayLength for regular enumerators

Implemented in Arp::System::Rsc::Services::RscReadEnumerator< T >, and Arp::System::Rsc::Services::RscImplReadEnumerator< T >.

EndRead()

template<class T >

virtual void Arp::System::Rsc::Services::IRscReadEnumerator< T >::EndRead ( void  )

pure virtual

Ends the operation to read the enumerator. All enumerator elements had to be already been read.

Implemented in Arp::System::Rsc::Services::RscReadEnumerator< T >, and Arp::System::Rsc::Services::RscImplReadEnumerator< T >.

ReadNext() [1/2]

template<class T >

virtual bool Arp::System::Rsc::Services::IRscReadEnumerator< T >::ReadNext ( RscArrayReader &  current )

pure virtual

Reads the next array enumerator element. Use this method only, if element contains object with an array.

Parameters

current

Reference to RscArrayReader. The given RscArrayReader will be configured by this method.

Returns

true if valid element was read

Implemented in Arp::System::Rsc::Services::RscReadEnumerator< T >, and Arp::System::Rsc::Services::RscImplReadEnumerator< T >.

ReadNext() [2/2]

template<class T >

virtual bool Arp::System::Rsc::Services::IRscReadEnumerator< T >::ReadNext ( T &  current )

pure virtual

Reads the next enumerator element.

Parameters

current

Place to store next element

Returns

true if valid element was read

Implemented in Arp::System::Rsc::Services::RscReadEnumerator< T >, and Arp::System::Rsc::Services::RscImplReadEnumerator< T >.
