类 ChunkedStream

java.lang.Object

org.jboss.netty.handler.stream.ChunkedStream

所有已实现的接口:

ChunkedInput

public class ChunkedStream
extends java.lang.Object
implements ChunkedInput

A ChunkedInput that fetches data from an InputStream chunk by chunk.

Please note that the InputStream instance that feeds data into ChunkedStream must implement InputStream.available() as accurately as possible, rather than using the default implementation. Otherwise, ChunkedStream will generate many too small chunks or block unnecessarily often.

构造器概要

构造器和说明
ChunkedStream(java.io.InputStream in) Creates a new instance that fetches data from the specified stream.
ChunkedStream(java.io.InputStream in, int chunkSize) Creates a new instance that fetches data from the specified stream.

void	close() Releases the resources associated with the stream.
long	getTransferredBytes() Returns the number of transferred bytes.
boolean	hasNextChunk() Returns true if and only if there is any data left in the stream.
boolean	isEndOfInput() Return true if and only if there is no data left in the stream and the stream has reached at its end.

构造器详细资料

ChunkedStream

public ChunkedStream(java.io.InputStream in)

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

ChunkedStream

public ChunkedStream(java.io.InputStream in,
             int chunkSize)

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

参数:

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

方法详细资料

getTransferredBytes

public long getTransferredBytes()

Returns the number of transferred bytes.

hasNextChunk

public boolean hasNextChunk()
                     throws java.lang.Exception

从接口复制的说明: ChunkedInput

Returns true if and only if there is any data left in the stream. Please note that false does not necessarily mean that the stream has reached at its end. In a slow stream, the next chunk might be unavailable just momentarily.

指定者:

hasNextChunk 在接口中 ChunkedInput

抛出:

java.lang.Exception

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

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 stream.

指定者:

close 在接口中 ChunkedInput

抛出:

java.lang.Exception

nextChunk

public java.lang.Object nextChunk()
                           throws java.lang.Exception

从接口复制的说明: ChunkedInput

Fetches a chunked data from the stream. The returned chunk is usually a ChannelBuffer, but you could extend an existing implementation to convert the ChannelBuffer into a different type that your handler or encoder understands. Once this method returns the last chunk and thus the stream has reached at its end, any subsequent ChunkedInput.isEndOfInput() call must return false.

指定者:

nextChunk 在接口中 ChunkedInput

返回:

the fetched chunk, which is usually ChannelBuffer. 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
