ChunkedInput<WebSocketFrame>

public final class WebSocketChunkedInput
extends java.lang.Object
implements ChunkedInput<WebSocketFrame>

A ChunkedInput that fetches data chunk by chunk for use with WebSocket chunked transfers.

Each chunk from the input data will be wrapped within a ContinuationWebSocketFrame. At the end of the input data, ContinuationWebSocketFrame with finalFragment will be written.

isEndOfInput

public boolean isEndOfInput()
                     throws java.lang.Exception

从接口复制的说明: ChunkedInput

Return true if and only if there is no data left in the stream and the stream has reached at its end.

指定者:

isEndOfInput 在接口中 ChunkedInput<WebSocketFrame>

返回:

true if and only if there is no data left in the stream and the stream has reached at its end.

抛出:

java.lang.Exception

close

public void close()
           throws java.lang.Exception

Releases the resources associated with the input.

指定者:

close 在接口中 ChunkedInput<WebSocketFrame>

抛出:

java.lang.Exception

返回:

WebSocketFrame contain chunk of data

抛出:

java.lang.Exception
