init()

bool metric_iterator::init ( const char *  group )

Create metric sources iterator, iterates metrics within single meter.

Sets the iterator to the first matching element (if any) or at eof.

Parameters

group

meter containing the metrics

Return values

false	: found
true	: not found or error initializing

next()

bool metric_iterator::next ( void  )

inline

Advance metric sources iterator to next value.

Sets the iterator to the next matching element (if any) or at eof.

Return values

false	: found
true	: not found

next_metric()
