构造器详细资料

AbstractContentDecoder

public AbstractContentDecoder(ReadableByteChannel channel,
                              SessionInputBuffer buffer,
                              BasicHttpTransportMetrics metrics)

Creates an instance of this class.

参数:

channel - the source channel.

buffer - the session input buffer that can be used to store session data for intermediate processing.

metrics - Transport metrics of the underlying HTTP transport.

方法详细资料

channel

protected ReadableByteChannel channel()

buffer

protected SessionInputBuffer buffer()

metrics

protected BasicHttpTransportMetrics metrics()

isCompleted

public boolean isCompleted()

从接口复制的说明: ContentDecoder

Returns true if the entity has been received in its entirety.

指定者:

isCompleted 在接口中 ContentDecoder

返回:

true if all the content has been consumed, false otherwise.

setCompleted

public void setCompleted(boolean completed)

Sets the completed status of this decoder. Normally this is not necessary (the decoder will automatically complete when the underlying channel returns EOF). It is useful to mark the decoder as completed if you have some other means to know all the necessary data has been read and want to reuse the underlying connection for more messages.

参数:

completed - the completed status of this decoder.

从以下版本开始:

4.4.11

setCompleted

protected void setCompleted()

Sets the completed status of this decoder to true. Normally this is not necessary (the decoder will automatically complete when the underlying channel returns EOF). It is useful to mark the decoder as completed if you have some other means to know all the necessary data has been read and want to reuse the underlying connection for more messages.

从以下版本开始:

4.4.11

readFromChannel

protected int readFromChannel(ByteBuffer dst)
                       throws IOException

Reads from the channel to the destination.

参数:

dst - destination.

返回:

number of bytes transferred.

抛出:

IOException

从以下版本开始:

4.3

fillBufferFromChannel

protected int fillBufferFromChannel()
                             throws IOException

Reads from the channel to the session buffer.

返回:

number of bytes transferred.

抛出:

IOException

从以下版本开始:

readFromChannel

protected int readFromChannel(ByteBuffer dst,
                              int limit)
                       throws IOException

Reads from the channel to the destination.

参数:

dst - destination.

limit - max number of bytes to transfer.

返回:

number of bytes transferred.

抛出:

IOException

从以下版本开始:

4.3

getTrailers

public List<? extends Header> getTrailers()

从接口复制的说明: ContentDecoder

Returns content trailers if available

指定者:
