Class BreadcrumbActionsBean

java.lang.Object

org.nuxeo.ecm.webapp.navigation.BreadcrumbActionsBean

All Implemented Interfaces:

Serializable, BreadcrumbActions

@Name(value="breadcrumbActions")
 @Scope(value=CONVERSATION)
 @Install(precedence=10)
public class BreadcrumbActionsBean
extends Object
implements BreadcrumbActions, Serializable

The new approach: keep all selected documents into a list. Add new document to the list each time a new document is selected, after rebuilding the path.

Algorithm for rebuilding the path:

d1 -> d2 -> d3 -> d4

A new document is selected, which is a child of d2, named d2.5. We need to add d2.5 to the list after all unneeded documents have been removed to the list. In the end the list should look like this: d1 -> d2 -> d2.5. We need to remove all the documents in the list after d2, and add d2.5 to the list. TODO: fix bug when selecting an item located on a different branch than the current one so that its parent is not found in the current branch

Method Detail

getMinPathSegmentsLen

protected int getMinPathSegmentsLen()

Minimum path segments that must be displayed without shrinking.

getMaxPathCharLen

protected int getMaxPathCharLen()

Maximum length path that can be displayed without shrinking.

getPathEllipsis

protected String getPathEllipsis()

getViewDomainsOutcome

protected String getViewDomainsOutcome()

navigateToParent

public String navigateToParent()

Specified by:

navigateToParent in interface BreadcrumbActions

navigateToPathElement

protected String navigateToPathElement(PathElement pathElement)

getBackendPath

@Factory(value="backendPath",
         scope=EVENT)
public List<PathElement> getBackendPath()

Computes the current path by making calls to backend. TODO: need to change to compute the path from the seam context state.

GR: removed the Factory annotation because it made the method be called too early in case of processing that involves changing the current document. Multiple invocation of this method is anyway very cheap.

Specified by:

getBackendPath in interface BreadcrumbActions

Returns:

isNavigationBreadcrumb

@Factory(value="isNavigationBreadcrumb",
         scope=EVENT)
public boolean isNavigationBreadcrumb()

shrinkPathIfNeeded

protected List<PathElement> shrinkPathIfNeeded(List<PathElement> paths)

makeBackendPathFromLabel

protected List<PathElement> makeBackendPathFromLabel(String label)

getUserDomains

public List<DocumentModel> getUserDomains()

isUserDomain

public boolean isUserDomain(DocumentModel doc)

resetUserDomains

@Observer(value={"locationSelectionChanged","documentChildrenChanged","documentChanged"})
public void resetUserDomains()
