template<     class BidirIt >class sub_match;		(dal C++11)

Il sub_match modello di classe viene utilizzato dal motore delle espressioni regolari per indicare sequenze di caratteri a cui corrisponde marcata sotto-espressioni.

Original:

The class template sub_match is used by the regular expression engine to denote sequences of characters matched by marked sub-expressions.

Una partita è una coppia [begin, end) all'interno dell'intervallo di riferimento di pari passo con l'espressione regolare, ma con funzioni di osservatori aggiuntivi per migliorare la chiarezza del codice.

Original:

A match is a [begin, end) pair within the target range matched by the regular expression, but with additional observer functions to enhance code clarity.

Solo il costruttore di default è accessibile al pubblico. Istanze di sub_match sono normalmente costruiti e popolato come parte di un contenitore std::match_results durante la lavorazione di uno degli algoritmi regex.

Original:

Only the default constructor is publicly accessible. Instances of sub_match are normally constructed and populated as a part of a std::match_results container during the processing of one of the regex algorithms.

Le funzioni membro restituire valori di default definiti meno che il membro matched è true.

Original:

The member functions return defined default values unless the matched member is true.

sub_match eredita da std::pair<BidirIt, BidirIt>, anche se non può essere trattata come un oggetto std::pair perché funzioni membro come swap e assegnazione non funzionerà come previsto.

Original:

sub_match inherits from std::pair<BidirIt, BidirIt>, although it cannot be treated as a std::pair object because member functions such as swap and assignment will not work as expected.
