Class WebSocketChunkedInput

java.lang.Object

io.netty.handler.codec.http.websocketx.WebSocketChunkedInput

All Implemented Interfaces:

io.netty.handler.stream.ChunkedInput<WebSocketFrame>

public final class WebSocketChunkedInput
extends Object
implements io.netty.handler.stream.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.

Constructor Summary

Constructors

Constructor and Description
WebSocketChunkedInput(io.netty.handler.stream.ChunkedInput<io.netty.buffer.ByteBuf> input) Creates a new instance using the specified input.
WebSocketChunkedInput(io.netty.handler.stream.ChunkedInput<io.netty.buffer.ByteBuf> input, int rsv) Creates a new instance using the specified input.

Method Summary

Modifier and Type	Method and Description
void	close() Releases the resources associated with the input.
boolean	isEndOfInput()
long	length()
long	progress()
WebSocketFrame	readChunk(io.netty.buffer.ByteBufAllocator allocator) Fetches a chunked data from the stream.
WebSocketFrame	readChunk(io.netty.channel.ChannelHandlerContext ctx) Deprecated. Use readChunk(ByteBufAllocator). Fetches a chunked data from the stream. Once this method returns the last chunk and thus the stream has reached at its end, any subsequent isEndOfInput() call must return true.

Constructor Detail

WebSocketChunkedInput

public WebSocketChunkedInput(io.netty.handler.stream.ChunkedInput<io.netty.buffer.ByteBuf> input)

Creates a new instance using the specified input.

Parameters:

input - ChunkedInput containing data to write

WebSocketChunkedInput

public WebSocketChunkedInput(io.netty.handler.stream.ChunkedInput<io.netty.buffer.ByteBuf> input,
                             int rsv)

Creates a new instance using the specified input.

Parameters:

input - ChunkedInput containing data to write

rsv - RSV1, RSV2, RSV3 used for extensions

Throws:

NullPointerException - if input is null

Method Detail

isEndOfInput

public boolean isEndOfInput()
                     throws Exception

Specified by:

isEndOfInput in interface io.netty.handler.stream.ChunkedInput<WebSocketFrame>

Returns:

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

Throws:

Exception

close

public void close()
           throws Exception

Releases the resources associated with the input.

Specified by:

close in interface io.netty.handler.stream.ChunkedInput<WebSocketFrame>

Throws:

Exception

readChunk

@Deprecated
public WebSocketFrame readChunk(io.netty.channel.ChannelHandlerContext ctx)
                                     throws Exception

Deprecated. Use readChunk(ByteBufAllocator). Fetches a chunked data from the stream. Once this method returns the last chunk and thus the stream has reached at its end, any subsequent isEndOfInput() call must return true.

Specified by:

readChunk in interface io.netty.handler.stream.ChunkedInput<WebSocketFrame>

Parameters:

ctx - ChannelHandlerContext context of channelHandler

Returns:

WebSocketFrame contain chunk of data

Throws:

Exception

readChunk

public WebSocketFrame readChunk(io.netty.buffer.ByteBufAllocator allocator)
                         throws Exception

Fetches a chunked data from the stream. Once this method returns the last chunk and thus the stream has reached at its end, any subsequent isEndOfInput() call must return true.

Specified by:

readChunk in interface io.netty.handler.stream.ChunkedInput<WebSocketFrame>

Parameters:

allocator - ByteBufAllocator

Returns:

WebSocketFrame contain chunk of data

Throws:

Exception

length

public long length()

Specified by:

length in interface io.netty.handler.stream.ChunkedInput<WebSocketFrame>

progress

public long progress()

Specified by:

progress in interface io.netty.handler.stream.ChunkedInput<WebSocketFrame>
