This class implements container data items that can store SMWSemanticData objects. Containers are not dataitems in the proper sense: they do not represent a single, opaque value that can be assigned to a property. Rather, a container represents a "subobject" with a number of property-value assignments. When a container is stored, these individual data assignments are stored – the data managed by SMW never contains any "container", just individual property assignments for the subobject. Likewise, when a container is used in search, it is interpreted as a patterns of possible property assignments, and this pattern is searched for.
The data encapsulated in a container data item is essentially an SMWSemanticData object of class SMWContainerSemanticData. This class allows the subject to be kept anonymous if not known (if no context page is available for finding a suitable subobject name). See the repsective documentation for details.
Being a mere placeholder/template for other data, an SMWDIContainer is not immutable as the other basic data items. New property-value pairs can always be added to the internal SMWContainerSemanticData.
SMWDIContainer::__construct | ( | SMWContainerSemanticData | $semanticData | ) |
Constructor. The given SMWContainerSemanticData object will be owned by the constructed object afterwards, and in particular will not allow further changes.
