close

public void close()

Close this stream and release all associated resources, checking first that the end of stream has been reached. Can safely be called even if the stream was previously closed. If a delta link was encountered before the stream was closed, it will be available via the DeltaStream.deltaLink property only after the stream is closed. If a next link was encountered before the stream was closed, it will be available via the DeltaStream.nextLink property only after the stream is closed.

DeltaStream.abort.

Overrides:

close in class DeltaStream

fromStream

public static JsonDeltaStream fromStream(CharStream stream,
                                         DataContext context)

Convert a character stream containing OData delta JSON encoding into a stream of delta items.

Parameters:

stream - Character stream.

context - Data context.

Returns:

Stream of delta items.

next

public boolean next()

If this stream has not been DeltaStream.close and has a next delta item, then advance to the next delta item and return true. Otherwise return false.

DeltaStream.hasCurrent, DeltaStream.hasEntity, DeltaStream.hasLink, DeltaStream.getCurrent, DeltaStream.getEntity, DeltaStream.getLink.

Specified by:

Returns:

`true` if there is a next delta item available.
