Method Detail

findImporter

public static Resource findImporter(Resource resource)

Looks up importer in the passed page resource

Parameters:

resource - The page resource which needs to be searched for importer resource

Returns:

The found importer resource. In case of multiple, the first found importer resource is returned

findImporters

public static java.util.List<Resource> findImporters(Resource resource)

Finds importer resources within the page resource passed. Doesn't look into sub pages.

Parameters:

resource - The page resource which needs to be searched for importer resource

Returns:

The list of importer resources found

findImporters

public static java.util.List<Resource> findImporters(Resource resource,
                                                     boolean recursive)

Finds importer resources within the passed page resource. Looks into sub pages if the recursive param is passed true

Parameters:

resource - The page resource which needs to be searched for importer resource

recursive - if true, all sub pages are looked up as well

Returns:

The list of importer resources found

checkCanvasPrimary

public static boolean checkCanvasPrimary(Resource resource)
                                  throws java.lang.IllegalArgumentException

Checks if the passed canvas is primary.

Parameters:

resource - The resource corresponding to a canvas

Returns:

true if the passed canvas resource is primary in nature

Throws:

java.lang.IllegalArgumentException - When the passed resource is not a valid canvas resource

checkCanvasSecondary

public static boolean checkCanvasSecondary(Resource resource)
                                    throws java.lang.IllegalArgumentException

Checks if the passed canvas is secondary.

Note: A design import typically results in one primary canvas accompanied by zero or more secondary canvases.

Parameters:

resource - The resource corresponding to a canvas

Returns:

true if the passed canvas resource is secondary in nature

Throws:

java.lang.IllegalArgumentException - When the passed resource is not a valid canvas resource

getCanvasDesign

public static Resource getCanvasDesign(Resource resource)

Returns the resource corresponding to the canvas design

Parameters:

resource - The resource corresponding to a canvas or its container importer component node

Returns:

Resource corresponding to the canvas design

getCanvas

public static Resource getCanvas(Resource resource)

Convenience method to get canvas from the importer. If a canvas resource is passed, it's returned back

Parameters:

resource -

Returns:

isCanvas

public static boolean isCanvas(Resource resource)

Checks if the passed resource corresponds to a generated canvas node based on the following heuristics:

• Its parent has the resource type ImporterConstants.RESOURCE_TYPE_IMPORTER

Parameters:

resource -

Returns:

isImporter

public static boolean isImporter(Resource resource)

Checks if the passed resource corresponds to importer

Parameters:

resource -

Returns:

isImporterPage

public static boolean isImporterPage(Page page)

Checks if the passed page is created using the ImporterConstants.PAGE_TEMPLATE_IMPORTER_PAGE template

Parameters:

page -

Returns:

isImporterPage

public static boolean isImporterPage(Resource resource)

Checks if the passed resource is a, or belongs to a page created using the ImporterConstants.PAGE_TEMPLATE_IMPORTER_PAGE template

Parameters:

resource - The page resource or a resource contained within the page

Returns:

deleteCanvasArtifact

public static void deleteCanvasArtifact(Resource resource)
                                 throws RepositoryException

Deletes the canvas artifact along with any dangling ascendants.

Parameters:

resource - Resource corresponding to a canvas artifact like canvas design or canvas component

Throws:

RepositoryException

deleteCanvasArtifact

public static void deleteCanvasArtifact(Resource resource,
                                        boolean cleanupDanglingAscendants)
                                 throws RepositoryException

Deletes the canvas artifact

Parameters:

resource - Resource corresponding to a canvas artifact like canvas design or canvas component

cleanupDanglingAscendants - flag to indicate if ascendants left dangling, because of the deleted canvas, also need to be cleaned up.

Throws:

RepositoryException

cleanupDanglingAscendants

public static void cleanupDanglingAscendants(Resource resource)
                                      throws RepositoryException

This method traverses up the hierarchy (uptil canvas dir) of the passed resource and deletes all nodes without children. Since the canvas artifacts are created in convention based structured folders, deletion of artifacts requires cleanup of the folders that were created to contain the artifact.

Throws:

RepositoryException

getDanglingAscendantRoot

public static Resource getDanglingAscendantRoot(Resource resource)
                                         throws RepositoryException

For internal use

Throws:

RepositoryException
