所有已实现的接口:

ChunkedInput<ByteBuf>

public class ChunkedNioStream
extends java.lang.Object
implements ChunkedInput<ByteBuf>

A ChunkedInput that fetches data from a ReadableByteChannel chunk by chunk. Please note that the ReadableByteChannel must operate in blocking mode. Non-blocking mode channels are not supported.

构造器详细资料

ChunkedNioStream

public ChunkedNioStream(java.nio.channels.ReadableByteChannel in)

Creates a new instance that fetches data from the specified channel.

ChunkedNioStream

public ChunkedNioStream(java.nio.channels.ReadableByteChannel in,
                int chunkSize)

Creates a new instance that fetches data from the specified channel.

参数:

chunkSize - the number of bytes to fetch on each readChunk(ChannelHandlerContext) call

方法详细资料

transferredBytes

public long transferredBytes()

Returns the number of transferred bytes.

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<ByteBuf>

抛出:

java.lang.Exception

close

public void close()
           throws java.lang.Exception

从接口复制的说明: ChunkedInput

Releases the resources associated with the input.

指定者:

close 在接口中 ChunkedInput<ByteBuf>

抛出:

java.lang.Exception

readChunk

public ByteBuf readChunk(ChannelHandlerContext ctx)
                  throws java.lang.Exception

从接口复制的说明: ChunkedInput

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 ChunkedInput.isEndOfInput() call must return true.

指定者:

readChunk 在接口中 ChunkedInput<ByteBuf>

返回:

the fetched chunk. null if there is no data left in the stream. Please note that null does not necessarily mean that the stream has reached at its end. In a slow stream, the next chunk might be unavailable just momentarily.

抛出:

java.lang.Exception
