Method Detail

dispose

void dispose()

Dispose this HierarchyManager

getRootEntry

NodeEntry getRootEntry()

Returns:

the root entry.

lookup

HierarchyEntry lookup(ItemId workspaceItemId)

Lookup of HierarchyEntry by its workspace Id that may be different if a entry (or any of its ancestors) has been transiently moved or reordered.

If the Hierarchy already lists the entry with the given workspaceItemId it is returned otherwise null. See getNodeEntry(NodeId) or getPropertyEntry(PropertyId) for methods that resolves the ItemId including lookup in the persistence layer if the entry has not been loaded yet.

Parameters:

workspaceItemId -

Returns:

the HierarchyEntry with the given workspaceItemId.

lookup

HierarchyEntry lookup(Path workspacePath)

Lookup of HierarchyEntry by its workspace path that may be different if a entry (or any of its ancestors) has been transiently moved or reordered.

If the Hierarchy already lists the entry with the given path it is returned otherwise null. See getNodeEntry(Path) or getPropertyEntry(Path) for methods that resolves the path including lookup in the persistence layer if the entry has not been loaded yet.

Parameters:

workspacePath -

Returns:

the HierarchyEntry with the given workspacePath.

getNodeEntry

NodeEntry getNodeEntry(NodeId nodeId)
                       throws ItemNotFoundException,
                              RepositoryException

Resolves a itemId into a HierarchyEntry.

Parameters:

nodeId -

Returns:

Throws:

PathNotFoundException

RepositoryException

ItemNotFoundException

getNodeEntry

NodeEntry getNodeEntry(Path qPath)
                       throws PathNotFoundException,
                              RepositoryException

Resolves a path into a NodeEntry.

Parameters:

qPath -

Returns:

Throws:

PathNotFoundException

RepositoryException

getPropertyEntry

PropertyEntry getPropertyEntry(PropertyId propertyId)
                               throws ItemNotFoundException,
                                      RepositoryException

Resolves a propertyId into a PropertyEntry.

Parameters:

propertyId -

Returns:

Throws:

PathNotFoundException

RepositoryException

ItemNotFoundException

getPropertyEntry

PropertyEntry getPropertyEntry(Path qPath)
                               throws PathNotFoundException,
                                      RepositoryException

Resolves a path into a PropertyEntry.

Parameters:

qPath -

Returns:

Throws:

PathNotFoundException

RepositoryException

getNodeState

NodeState getNodeState(Path qPath)
                       throws PathNotFoundException,
                              RepositoryException

Retrieves the NodeEntry corresponding to the given path and resolves it to the underlying NodeState.

Parameters:

qPath -

Returns:

Throws:

PathNotFoundException

RepositoryException

getPropertyState

PropertyState getPropertyState(Path qPath)
                               throws PathNotFoundException,
                                      RepositoryException

Retrieves the PropertyEntry corresponding to the given path and resolves it to the underlying PropertyState.

Parameters:

qPath -

Returns:

Throws:

PathNotFoundException

RepositoryException

getDepth

int getDepth(HierarchyEntry hierarchyEntry)
             throws ItemNotFoundException,
                    RepositoryException

Returns the depth of the specified item. The depth reflects the absolute hierarchy level.

Parameters:

hierarchyEntry -

Returns:

the depth of the specified item

Throws:

RepositoryException - if another error occurs

ItemNotFoundException

getRelativeDepth

int getRelativeDepth(NodeEntry ancestor,
                     HierarchyEntry descendant)
                     throws ItemNotFoundException,
                            RepositoryException

Returns the depth of the specified descendant relative to the given ancestor. If ancestor and descendant denote the same item 0 is returned. If ancestor does not denote an ancestor -1 is returned.

Parameters:

ancestor - NodeEntry that must be an ancestor of the descendant

descendant - HierarchyEntry

Returns:

the relative depth; -1 if ancestor does not denote an ancestor of the item denoted by descendant (or itself).

Throws:

ItemNotFoundException - If either of the specified id's does not denote an existing item.

RepositoryException - If another error occurs.
