org.apache.hc.core5.http.impl.io.SessionOutputBufferImpl

所有已实现的接口:

SessionOutputBuffer

public class SessionOutputBufferImpl
extends Object
implements SessionOutputBuffer

Abstract base class for session output buffers that stream data to an arbitrary OutputStream. This class buffers small chunks of output data in an internal byte array for optimal output performance.

writeLine(CharArrayBuffer, OutputStream) method of this class uses CR-LF as a line delimiter.

SessionOutputBufferImpl

public SessionOutputBufferImpl(BasicHttpTransportMetrics metrics,
                               int bufferSize,
                               int fragmentSizeHint,
                               CharsetEncoder charEncoder)

Creates new instance of SessionOutputBufferImpl.

参数:

metrics - HTTP transport metrics.

bufferSize - buffer size. Must be a positive number.

fragmentSizeHint - fragment size hint defining a minimal size of a fragment that should be written out directly to the socket bypassing the session buffer. Value 0 disables fragment buffering.

charEncoder - charEncoder to be used for encoding HTTP protocol elements. If null simple type cast will be used for char to byte conversion.

                               CharsetEncoder encoder)

方法详细资料

capacity

public int capacity()

从接口复制的说明: SessionOutputBuffer

Returns total capacity of the buffer

指定者:

capacity 在接口中 SessionOutputBuffer

返回:

total capacity

length

public int length()

从接口复制的说明: SessionOutputBuffer

Return length data stored in the buffer

指定者:

length 在接口中 SessionOutputBuffer

返回:

data length

available

public int available()

从接口复制的说明: SessionOutputBuffer

Returns available space in the buffer.

指定者:

available 在接口中 SessionOutputBuffer

返回:

available space.

flush

public void flush(OutputStream outputStream)
           throws IOException

从接口复制的说明: SessionOutputBuffer

Flushes this session buffer and forces any buffered output bytes to be written out. The general contract of flush is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination.

指定者:

flush 在接口中 SessionOutputBuffer

抛出:

IOException - if an I/O error occurs.

write

public void write(byte[] b,
                  int off,
                  int len,
                  OutputStream outputStream)
           throws IOException

从接口复制的说明: SessionOutputBuffer

Writes len bytes from the specified byte array starting at offset off to this session buffer.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

指定者:

write 在接口中 SessionOutputBuffer

参数:

b - the data.

off - the start offset in the data.

len - the number of bytes to write.

抛出:

IOException - if an I/O error occurs.

write

public void write(byte[] b,
                  OutputStream outputStream)
           throws IOException

从接口复制的说明: SessionOutputBuffer

Writes b.length bytes from the specified byte array to this session buffer.

指定者:

write 在接口中 SessionOutputBuffer

参数:

b - the data.

抛出:

IOException - if an I/O error occurs.

write

public void write(int b,
                  OutputStream outputStream)
           throws IOException

从接口复制的说明: SessionOutputBuffer

Writes the specified byte to this session buffer.

指定者:

write 在接口中 SessionOutputBuffer

参数:

b - the byte.

抛出:

IOException - if an I/O error occurs.

writeLine

public void writeLine(CharArrayBuffer charbuffer,
                      OutputStream outputStream)
               throws IOException

Writes characters from the specified char array followed by a line delimiter to this session buffer.

This method uses CR-LF as a line delimiter.

指定者:

writeLine 在接口中 SessionOutputBuffer

参数:

charbuffer - the buffer containing chars of the line.

抛出:

IOException - if an I/O error occurs.

getMetrics

public HttpTransportMetrics getMetrics()

从接口复制的说明: SessionOutputBuffer

Returns HttpTransportMetrics for this session buffer.

指定者:

getMetrics 在接口中 SessionOutputBuffer

返回:

transport metrics.
