Detailed Description

template<class T>
class Arp::System::Rsc::Services::RscImplReadEnumerator< T >

Implements IRscReadEnumeratorfor the service implementations. This should only be used in the implementation. The read callbacks have to be implemented and set by the service.

Member Function Documentation

BeginRead()

template<class T >

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

inlineoverridevirtual

Begins the operation to read the enumerator.

Returns

Number of elements for array enumerators. UndefinedArrayLength for regular enumerators

Implements Arp::System::Rsc::Services::IRscReadEnumerator< T >.

EndRead()

template<class T >

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

inlineoverridevirtual

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

Implements Arp::System::Rsc::Services::IRscReadEnumerator< T >.

ReadNext() [1/2]

template<class T >

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

inlineoverridevirtual

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

Implements Arp::System::Rsc::Services::IRscReadEnumerator< T >.

ReadNext() [2/2]

template<class T >

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

inlineoverridevirtual

Reads the next enumerator element.

Parameters

current

Place to store next element

Returns

true if valid element was read

Implements Arp::System::Rsc::Services::IRscReadEnumerator< T >.
