类 ChunkedOutputStream

java.lang.Object

java.io.OutputStream

depends.org.apache.http.impl.io.ChunkedOutputStream

所有已实现的接口:

java.io.Closeable, java.io.Flushable, java.lang.AutoCloseable

@NotThreadSafe
public class ChunkedOutputStream
extends java.io.OutputStream

Implements chunked transfer coding. The content is sent in small chunks. Entities transferred using this output stream can be of unlimited length. Writes are buffered to an internal buffer (2048 default size).

Note that this class NEVER closes the underlying stream, even when close gets called. Instead, the stream will be marked as closed and no further output will be permitted.

ChunkedOutputStream

@Deprecated
public ChunkedOutputStream(SessionOutputBuffer out,
                              int bufferSize)
                    throws java.io.IOException

已过时。 (4.3) use ChunkedOutputStream(int, SessionOutputBuffer)

Wraps a session output buffer and chunk-encodes the output.

参数:

out - The session output buffer

bufferSize - The minimum chunk size (excluding last chunk)

抛出:

java.io.IOException - not thrown

ChunkedOutputStream

@Deprecated
public ChunkedOutputStream(SessionOutputBuffer out)
                    throws java.io.IOException

已过时。 (4.3) use ChunkedOutputStream(int, SessionOutputBuffer)

Wraps a session output buffer and chunks the output. The default buffer size of 2048 was chosen because the chunk overhead is less than 0.5%

参数:

out - the output buffer to wrap

抛出:

java.io.IOException - not thrown

ChunkedOutputStream

public ChunkedOutputStream(int bufferSize,
                   SessionOutputBuffer out)

Wraps a session output buffer and chunk-encodes the output.

参数:

bufferSize - The minimum chunk size (excluding last chunk)

out - The session output buffer

方法详细资料

flushCache

protected void flushCache()
                   throws java.io.IOException

Writes the cache out onto the underlying stream

抛出:

java.io.IOException

flushCacheWithAppend

protected void flushCacheWithAppend(byte[] bufferToAppend,
                        int off,
                        int len)
                             throws java.io.IOException

Writes the cache and bufferToAppend to the underlying stream as one large chunk

抛出:

java.io.IOException

writeClosingChunk

protected void writeClosingChunk()
                          throws java.io.IOException

抛出:

java.io.IOException

finish

public void finish()
            throws java.io.IOException

Must be called to ensure the internal cache is flushed and the closing chunk is written.

抛出:

java.io.IOException - in case of an I/O error

write

public void write(int b)
           throws java.io.IOException

指定者:

write 在类中 java.io.OutputStream

抛出:

java.io.IOException

write

public void write(byte[] b)
           throws java.io.IOException

Writes the array. If the array does not fit within the buffer, it is not split, but rather written out as one large chunk.

覆盖:

write 在类中 java.io.OutputStream

抛出:

java.io.IOException

write

public void write(byte[] src,
         int off,
         int len)
           throws java.io.IOException

Writes the array. If the array does not fit within the buffer, it is not split, but rather written out as one large chunk.

覆盖:

write 在类中 java.io.OutputStream

抛出:

java.io.IOException

flush

public void flush()
           throws java.io.IOException

Flushes the content buffer and the underlying stream.

指定者:

flush 在接口中 java.io.Flushable

覆盖:

flush 在类中 java.io.OutputStream

抛出:

java.io.IOException

close

public void close()
           throws java.io.IOException

Finishes writing to the underlying stream, but does NOT close the underlying stream.

指定者:

close 在接口中 java.io.Closeable

指定者:

close 在接口中 java.lang.AutoCloseable

覆盖:

close 在类中 java.io.OutputStream

抛出:

java.io.IOException
