Method Details

rename

public void rename(String name)

Specified by:

rename in interface FileSystemItem

delete

public void delete()

Specified by:

delete in interface FileSystemItem

canMove

public boolean canMove(FolderItem dest)

Specified by:

canMove in interface FileSystemItem

move

public FileSystemItem move(FolderItem dest)

Specified by:

move in interface FileSystemItem

getCanScrollDescendants

public boolean getCanScrollDescendants()

Description copied from interface: FolderItem

Returns true if the FolderItem.scrollDescendants(String, int, long) API can be used.

Specified by:

getCanScrollDescendants in interface FolderItem

scrollDescendants

public ScrollFileSystemItemList scrollDescendants(String scrollId,
 int batchSize,
 long keepAlive)

Description copied from interface: FolderItem

Retrieves at most batchSize FileSystemItem descendants for 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.

This method is protected by a Semaphore, made available by FileSystemItemAdapterService.getScrollBatchSemaphore(), to limit the number of concurrent executions and avoid too much memory pressure.

Specified by:

scrollDescendants in interface FolderItem

getCanCreateChild

public boolean getCanCreateChild()

Specified by:

getCanCreateChild in interface FolderItem

createFolder

public FolderItem createFolder(String name,
 boolean overwrite)

Specified by:

Parameters:

overwrite - allows to overwrite an existing folder with the same title

createFile

public FileItem createFile(Blob blob,
 boolean overwrite)

Specified by:

createFile in interface FolderItem

Parameters:

overwrite - allows to overwrite an existing file with the same title

equals

public boolean equals(Object obj)

Overrides:

equals in class AbstractFileSystemItem

hashCode

public int hashCode()

Overrides:

hashCode in class AbstractFileSystemItem

setCanCreateChild

protected void setCanCreateChild(boolean canCreateChild)
