Method Detail

getChildren

List<FileSystemItem> getChildren()

getCanScrollDescendants

boolean getCanScrollDescendants()

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

Since:

8.3

scrollDescendants

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

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.

Throws:

UnsupportedOperationException - if getCanScrollDescendants() returns false.

Since:

8.3
