15.18 ISServerIterator

#include <is/serveriterator.h>

IPCPartiiton p( "MyPartition" );

ISServerIterator it( p );

This class enumerates IS servers for the IS repository in a particular partition.

The "current item" is undefined immediately after construction - one must define it by using operator() or some other valid operator.

ISServerIterator( const IPCPartition & partition );

Constructs new ISServerIterator object which enumerates all IS servers in the partition IPC partition.

Throws daq::is::InvalidPartition is the given partition does not exist.

ISServerIterator( const IPCPartition & partition, const std::string & regexp );

Constructs new ISServerIterator object which enumerates all IS servers, whose names match the given regexp regular expression, in the partition IPC partition.

Throws daq::is::InvalidPartition is the given partition does not exist or daq::is::InvalidCriteria is the given string is not a valid regular expression.

bool

operator()();

Advances the iterator one position. Returns true if new position is valid, false otherwise.

bool

operator++();

Advances the iterator one position. Returns true if new position is valid, false otherwise.

bool

operator--();

Retreats the iterator to the previous position. Returns true if new position is valid, false otherwise.

bool

operator++(int);

Advances the iterator one position. Returns true if new position is valid, false otherwise.

bool

operator--(int);

Retreats the iterator to the previous position. Returns true if new position is valid, false otherwise.you

size_t

entries();

Returns the number of the IS servers in the iterator.

const char *

host();

Returns the name of the host where the IS servers process at the current iterator position is running.

const char *

name();

Returns the name of the IS server at the iterator's current position.

const char *

owner();

Returns the name of the owner of the IS servers process at the current iterator position.

size_t

pid();

Returns the pid of the IS servers process at the current iterator position.

void

reset();

Resets the iterator to the state it had immediately after construction.
