Detailed Description

This is an abstraction of a XMPP stanza.

You can create a new Stanza from an existing Tag (or another stanza).

Constructor & Destructor Documentation

Stanza

(

const Tag *

tag

)

Creates a new Stanza from a deep copy of the given Tag.

Parameters:

tag

The Tag to create the Stanza from.

Since:

0.7

Note:

While the signature of this constructor in 0.7 is the the same as in older versions, semantics have changed. The copy created by this constructor is no longer a shallow one. You have to make sure the copy is deleted properly.

Definition at line 32 of file stanza.cpp.

Stanza	(	const std::string &	name,
		const std::string &	cdata = "",
		const std::string &	xmllang = "default",
		bool	incoming = false
	)

Creates a new Stanza with given name and optional CData.

Parameters:

	name	The name of the root tag.
	cdata	Initial XML character data for the tag.
	xmllang	The value of the xmllang attribute. The stanza's primary language.
	incoming	Indicates whether tag names, attributes, attribute values, and cdata shall be escaped (false, default) or not (true).
