Included Services - Details
GroupAccess
Description
is the basic service providing read access to a group element of the hierarchy.

Any child and descendant objects support modifying access as well, unless they represent a read-only tree element as indicated by PropertyAttribute::READONLY.

Exported Interfaces - Details
::com::sun::star::container::XNameReplace
Description
allows replacing values.

This service extends the interface ::com::sun::star::container::XNameAccess supported by service GroupAccess to allow changing values. This strongly overlaps with functionality available through PropertyHierarchy (from GroupAccess), so that xGroup.setPropertyValue( aName, aValue ) is equivalent to xGroup.replaceByName( aName, aValue ).

Changes can be observed by registering a listener with interface ::com::sun::star::beans::XPropertySet or ::com::sun::star::beans::XMultiPropertySet.

Elements of this group may be replaced only if they are of simple type. The type returned by ::com::sun::star::container::XElementAccess::getElementType() must not be an interface type. Replacing whole subtrees is not supported.

Apache OpenOffice is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.
