TAO_CosNotification: TAO_Notify::XML

TAO_Notify::XML_Saver::XML_Saver ( bool timestamp = true )

Construct an XML_Saver. Initialization is deferred to "open()"

TAO_Notify::XML_Saver::~XML_Saver ( ) [virtual]

bool TAO_Notify::XML_Saver::open	(	const ACE_CString &	file_name,
		size_t	backup_count
	)

Open the output file.

Parameters:

file_name

the fully qualified file name

Returns:: true if successful

bool TAO_Notify::XML_Saver::begin_object	(	CORBA::Long	id,
		const ACE_CString &	type,
		const NVPList &	attrs,
		bool	changed
	)			`[virtual]`

Begin the storage of an object.

Call this function with the type and ID of an object to be stored. This object may have children, and this will necessitate nested calls to begin_object. Design principle: Names should be descriptive enough to allow the objects' parent to create an instance of the desired class. This instance will be registered with the poa using the id. The instance itself should will load its own attributes. Example <proxy type="push_supplier" events="any" id="20"...> is not a good design because the name "proxy" is not descriptive enough. "<structured_proxy_push_supplier id="20"...> is better because this allows the parent to create the correct type of object without decoding attributes.

Parameters:

	id	numeric id for this object
	type	string containing the unique type name for this class of objects
	attrs	a collection of name/value attributes
	change	true if this object's attributes have changed.

Returns:: bool want_all_children. If true even changed children should be saved.

Implements TAO_Notify::Topology_Saver.

void TAO_Notify::XML_Saver::end_object	(	CORBA::Long	id,
		const ACE_CString &	type
	)			`[virtual]`

End the storage of an object.

This function should be called to end the scope of the current object and commit it to the persistent store.

Implements TAO_Notify::Topology_Saver.

void TAO_Notify::XML_Saver::close ( void ) [virtual]

Close the saver.

This is not pure virtual. The default implementation does nothing.

There should be a corresponding open, but the signature may vary based on the type of saver, so we can't include it in the interface.

Reimplemented from TAO_Notify::Topology_Saver.

void TAO_Notify::XML_Saver::backup_file_name	(	char *	file_path,
		int	nfile
	)			`[private]`

FILE* TAO_Notify::XML_Saver::output_ [private]

A stream representing our current output.

bool TAO_Notify::XML_Saver::close_out_ [private]

ACE_CString TAO_Notify::XML_Saver::base_name_ [private]

the name of the output file

size_t TAO_Notify::XML_Saver::backup_count_ [private]

bool TAO_Notify::XML_Saver::timestamp_ [private]

true to enable timestamping

ACE_CString TAO_Notify::XML_Saver::indent_ [private]

A string consisting of spaces that is our current indentation level.
