## Member Function Documentation

## ◆ addOrReplaceNode()

void addOrReplaceNode | ( | [in] string | aName,
|  | [in] short | aAttributes )
raises | ( | MalformedDataException,
|  | com::sun::star::lang::WrappedTargetException ) |  |  |

receives notification that a new item is started.

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

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

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

Parameters

  aName | specifies the name of the item.
  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.

Exceptions

  com::sun::star::configuration::backend::MalformedDataException | if there isn't a set node in progress currently if there already was a change to a node of that name if the template for the new node is not found if an item of that name on a lower layer is not removable 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

Exceptions

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

## ◆ addOrReplaceNodeFromTemplate()

void addOrReplaceNodeFromTemplate | ( | [in] string | aName,
|  | [in] TemplateIdentifier | aTemplate,
|  | [in] short | aAttributes )
raises | ( | MalformedDataException,
|  | com::sun::star::lang::WrappedTargetException ) |  |  |

receives notification that a new item based on a particular template is started.

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

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

Parameters

  aName | specifies the name of the item.
  aTemplate | specifies the template to use for the new node
  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.

Exceptions

  com::sun::star::configuration::backend::MalformedDataException | if there isn't a set node in progress currently if there already was a change to a node of that name if the template for the new node is not found if the template is not a valid item type for the containing set if an item of that name on a lower layer is not removable 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

Exceptions

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

  com::sun::star::configuration::backend::NodeAttribute

## ◆ addProperty()

void addProperty | ( | [in] string | aName,
|  | [in] short | aAttributes,
|  | [in] type | aType )
raises | ( | MalformedDataException,
|  | com::sun::star::lang::WrappedTargetException ) |  |  |

receives notification that a property having a VOID value is added to the current node.

The current node must be extensible.

Parameters

  aName | specifies the name of the new property.
  aAttributes | specifies the attributes of the new property.

The value is a combination of NodeAttribute flags and may also contain the SchemaAttribute::REQUIRED flag.

NodeAttribute::MANDATORY need not be set, as dynamically added properties always are mandatory in subsequent layers.

Parameters

  aType | specifies the type of the new property.

Exceptions

  com::sun::star::configuration::backend::MalformedDataException | if there isn't an extensible node in progress currently if a property with that name already exists if the specified type is not allowed for a property if the name is not a valid property name if the attributes are not valid for the property

Not every implementation can detect each condition

Exceptions

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

  com::sun::star::configuration::backend::SchemaAttribute

## ◆ addPropertyWithValue()

void addPropertyWithValue | ( | [in] string | aName,
|  | [in] short | aAttributes,
|  | [in] any | aValue )
raises | ( | MalformedDataException,
|  | com::sun::star::lang::WrappedTargetException ) |  |  |

receives notification that a property having a non-VOID value is added to the current node.

The current node must be extensible.

Parameters

  aName | specifies the name of the new property.
  aAttributes | specifies the attributes of the new property.

The value is a combination of NodeAttribute flags and may also contain the SchemaAttribute::REQUIRED flag.

NodeAttribute::MANDATORY need not be set, as dynamic properties always are mandatory in subsequent layers.

Parameters

  aValue | specifies the value of the new property.

The value also determines the type. Therefore the value must not be VOID.

Exceptions

  com::sun::star::configuration::backend::MalformedDataException | if there isn't an extensible node in progress currently if a property with that name already exists if the type of the value is not an allowed type or if the value is VOID if the name is not a valid property name if the value is not valid for the property if the attributes are not valid for the property

Not every implementation can detect each condition

Exceptions

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

Parameters

  aType | specifies the type of the property.

This must be the same type as is already defined in the schema or lower layers, unless the previous type was unspecified (as indicated by com::sun::star::uno::TypeClass::ANY.)

A VOID type indicates that the type is unspecified in this layer. In this case any subsequent value may be of a generic type (e.g. string or - for list values - string[].) Such values may be converted to the type defined in the schema by the implementation.

Parameters

  bClear | if TRUE, specifies that the property should be cleared to an empty state by discarding all values from lower layers prior to applying the overrides.

Exceptions

  com::sun::star::configuration::backend::MalformedDataException | if there isn't a group or extensible node in progress currently if there already was a change to a property of that name if there is no property with that name if the property is read-only if the type does not match the type of the property if a type is missing and cannot be determined otherwise if the name is not a valid property name if the attributes are not valid for the property
