public class TreeWalkerForPublicationDetail
extends AbstractCmisObjectsTreeWalker
    A CmisObjectsTreeWalker object that knows how to walk down the subtree rooted to a publication in a given Silverpeas application. The publication is a localized contribution that can have a content (form, rich text (WYSIWYG), ...) and that can have one or more documents attached to it.

      • prepareChildDataCreation

        protected void prepareChildDataCreation​(LocalizedResource publication,
                                        CmisProperties properties,
                                        org.apache.chemistry.opencmis.commons.data.ContentStream contentStream,
                                        String language)
        Description copied from class: AbstractCmisObjectsTreeWalker
        Prepares the creation of the object in Silverpeas from the specified CMIS properties and content stream, and in the given language. The preparation can update some CMIS properties and some content stream attributes required to create the object as a child of the given parent. This method is invoked by the AbstractCmisObjectsTreeWalker.createChildData(String, CmisProperties, ContentStream, String) method before the creation of the child itself. By default, this method throws the CmisNotSupportedException exception.
        Overrides:
        prepareChildDataCreation in class AbstractCmisObjectsTreeWalker
        Parameters:
        publication - the resource in Silverpeas for which a new object has to be created.
        properties - the CMIS properties of the object to create.
        contentStream - a stream on a content from which a document has to be created. If not a document, can be null.
        language - the ISO 639-1 code of the language in which the textual properties of the object as well as the content (if any) are expressed.

      • browseParentsOfObject

        protected List<org.apache.chemistry.opencmis.commons.data.ObjectParentData> browseParentsOfObject​(LocalizedResource object,

        Description copied from class: AbstractCmisObjectsTreeWalker
        Browses for the parents in the CMIS objects tree of the specified Silverpeas object. In a CMIS objects tree, a child can have direct one or several parents. This method returns all of them. However, as the browsing of the CMIS objects tree depends on the type of its node and hence on the type of the objects in Silverpeas, the browsing is delegated to the walker that knows how to handle such a Silverpeas object.
        Specified by:
        browseParentsOfObject in class AbstractCmisObjectsTreeWalker
        Parameters:
        object - an identifiable object in Silverpeas.
        filtering - the filtering rules to apply on the CMIS data to return.
        Returns:
        a list of ObjectParentData elements, each of them being a wrapper of an ObjectData instance with the path of the specified object relative to this parent. The CMIS data are carried by the ObjectData object. If the specified object isn't file-able or it is the root folder (the virtual root space in Silverpeas), then an empty list is returned.
