Methods' Details
startUpdate
void
startUpdate()
raises( MalformedDataException,
::com::sun::star::lang::IllegalAccessException,
::com::sun::star::lang::WrappedTargetException );

Description
receives notification that a update or description is started.
Throws
com::sun::star::configuration::backend::MalformedDataException if the update already was started
Throws
com::sun::star::lang::IllegalAccessException if the target layer is read-only

Some implementations can only detect this when executing XUpdateHandler::endUpdate()

Throws
com::sun::star::lang::WrappedTargetException if an error occurs processing the event.
endUpdate
void
endUpdate()
raises( MalformedDataException,
::com::sun::star::lang::IllegalAccessException,
::com::sun::star::lang::WrappedTargetException );

Description
receives notification that the current update description is complete.

Must match a previous call to XUpdateHandler::startUpdate().

Throws
com::sun::star::configuration::backend::MalformedDataException
  • if no update is started at all
  • if invalid data is detected in the update
  • if there is an unfinished subnode in progress
  • if the update tries to change read-only data

Not every implementation can detect each condition

Throws
com::sun::star::lang::IllegalAccessException if the target layer is read-only
Throws
com::sun::star::lang::WrappedTargetException if an error occurs processing the event.
modifyNode
void
modifyNode( [in] string  aName,
[in] short  aAttributes,
[in] short  aAttributeMask,
[in] boolean  bReset )
raises( MalformedDataException,
::com::sun::star::lang::WrappedTargetException );

Description
receives notification that a modification of a node is started.

Subsequent calls describe changes to properties and items or members of the node until a matching call to XUpdateHandler::endNode() is encountered.

Parameter aName
specifies the name of the node.
Parameter aAttributes
specifies attribute values to be applied to the node in the current layer.

The value is a combination of NodeAttribute flags.

Only attributes which are selected in aAttributeMask are changed.

Parameter aAttributeMask
specifies which attributes should be changed for the node.

The value is a combination of NodeAttribute flags.

Parameter bReset
if true, specifies that the node should be reset to its default state as given by lower layers and the schema or template prior to applying the changes.
Throws
com::sun::star::configuration::backend::MalformedDataException
  • if there isn't an update in progress at all
  • if a node is not valid in this place
  • if there already was a change to that node
  • if there is no node with that name
  • if the node is read-only
  • if the name is not a valid node name
  • if the attributes or mask are not valid for the node

Not every implementation can detect each condition

Throws
com::sun::star::lang::WrappedTargetException if an error occurs processing the event.

::com::sun::star::lang::WrappedTargetException );

Description
receives notification that a node is started as a new item.

The current node must be a set and a preexisting item (if any) must be removeable.

The new item will be created from the default template of the set.

Subsequent calls describe the difference from the template of properties, items or members of the node until a matching call to XUpdateHandler::endNode() is encountered.

Parameter aName
specifies the name of the new item.
Parameter aAttributes
specifies attribute values to be applied to the new node.

The value is a combination of NodeAttribute flags. Note that NodeAttribute::FUSE has an impact on the semantics of this method.

Throws
com::sun::star::configuration::backend::MalformedDataException
  • if there isn't a set node in progress currently
  • if there already was a change to an item of that name
  • if the template for the new node is not found
  • if an item of that name exists and is not removeable
  • if the name is not a valid item name
  • if the attributes are not valid for the node

Not every implementation can detect each condition

Throws
com::sun::star::lang::WrappedTargetException if an error occurs processing the event.
