Interface DocumentModel

  • All Superinterfaces:
    Serializable
    All Known Implementing Classes:
    DeletedDocumentModel, DocumentModelImpl, ShallowDocumentModel, SimpleDocumentModel
    public interface DocumentModel
extends Serializable
    The document model is a serializable representation of a core document.

    The document model is made from several data models, each data model is bound to a schema. All the information about a document (like security) is expressed using schemas (and implicitly data models).

    Data models are lazily loaded as they are needed. At document model creation only data models corresponding to the default schemas are loaded. The default schemas are configured in the type manager through extension points.

              throws PropertyException
        Gets a property given a xpath.

        Note that what's called xpath in this context is not an actual XPath as specified by the w3c. Main differences are that in our xpath:

        • Indexes start at 0 instead of 1
        • You can express foo/bar[i]/baz as foo/i/baz
        The latter is possible because in Nuxeo lists of complex elements are homogenous, so the name of the second-level element is implied.
