bool xmppd::ns_decl_list::check_prefix	(	const std::string &	prefix,
		const std::string &	ns_iri
	)		const

check if a namespace is already declared as we need it

Parameters:

prefix	the prefix we want to check
ns_iri	the IRI we check if the prefix maps to it

Returns:

true if the namespace prefix is already declared as we need it

void xmppd::ns_decl_list::delete_last

(

const std::string &

prefix

)

delete the last declaration of a prefix

Parameters:

prefix

the prefix, that should get undeclared

char const * xmppd::ns_decl_list::get_nsiri

(

const std::string &

prefix

)

const

get the namespace IRI, that is currently bound to a namespace prefix

Parameters:

prefix

the namespace prefix to check

Returns:

the namespace IRI the prefix is bound to, NULL if the prefix is not declared

Exceptions:

std::invalid_argument

if prefix is not bound to a namespace

get the latest prefix, that is bould to a namespace IRI

Parameters:

iri	the namespace IRI to search for
accept_default_prefix	if set to false, the method will only search for a non-default prefix

Returns:

the latest prefix, that is bould to this namespace IRI

Exceptions:

std::invalid_argument

if namespace is not declared

Parameters:

iri	the namespace IRI to search for

Returns:

the latest prefix, that is bould to this namespace IRI
