Method Details

getTopLevelFolder

FolderItem getTopLevelFolder(NuxeoPrincipal principal)

Gets the top level FolderItem for the given principal.

exists

boolean exists(String id,
 NuxeoPrincipal principal)

Returns true if a FileSystemItem with the given id exists for the given principal.

See Also:

• FileSystemItemFactory.exists(String, NuxeoPrincipal)

getFileSystemItemById

FileSystemItem getFileSystemItemById(String id,
 NuxeoPrincipal principal)

Gets the FileSystemItem with the given id for the given principal.

Returns:

the FileSystemItem or null if none matches the given id

See Also:

• FileSystemItemFactory.getFileSystemItemById(String, NuxeoPrincipal)

getFileSystemItemById

FileSystemItem getFileSystemItemById(String id,
 String parentId,
 NuxeoPrincipal principal)

Gets the FileSystemItem with the given id and parent id for the given principal.

Returns:

the FileSystemItem or null if none matches the given id and parent id

Since:

6.0

See Also:

• getFileSystemItemById(String, NuxeoPrincipal)

getChildren

List<FileSystemItem> getChildren(String id,
 NuxeoPrincipal principal)

Gets the children of the FileSystemItem with the given id for the given principal.

See Also:

• FolderItem.getChildren()

scrollDescendants

ScrollFileSystemItemList scrollDescendants(String id,
 NuxeoPrincipal principal,
 String scrollId,
 int batchSize,
 long keepAlive)

Retrieves at most batchSize descendants of the FolderItem with the given id for the given principal and the given scrollId.

When passing a null scrollId the initial search request is executed and the first batch of results is returned along with a scrollId which should be passed to the next call in order to retrieve the next batch of results.

Ideally, the search context made available by the initial search request is kept alive during keepAlive milliseconds if keepAlive is positive.

Results are not necessarily sorted.

Since:

8.3

• FolderItem.scrollDescendants(String, int, long)

canMove

boolean canMove(String srcId,
