SessionOutputBuffer

org.apache.http.io.SessionOutputBuffer
Known Indirect Subclasses

Class Overview

Session output buffer for blocking connections. This interface is similar to OutputStream class, but it also provides methods for writing lines of text.

Implementing classes are also expected to manage intermediate data buffering for optimal output performance.

Summary

Public Methods
abstract void flush()
Flushes this session buffer and forces any buffered output bytes to be written out.
abstract HttpTransportMetrics getMetrics()
Returns HttpTransportMetrics for this session buffer.
abstract void write(byte[] b, int off, int len)
Writes len bytes from the specified byte array starting at offset off to this session buffer.
abstract void write(byte[] b)
Writes b.length bytes from the specified byte array to this session buffer.
abstract void write(int b)
Writes the specified byte to this session buffer.
abstract void writeLine(CharArrayBuffer buffer)
Writes characters from the specified char array followed by a line delimiter to this session buffer.
abstract void writeLine(String s)
Writes characters from the specified string followed by a line delimiter to this session buffer.

Public Methods

public abstract void flush ()

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.

Throws
IOException if an I/O error occurs.

public abstract HttpTransportMetrics getMetrics ()

Returns HttpTransportMetrics for this session buffer.

Returns
  • transport metrics.

public abstract void write (byte[] b, int off, int len)

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.

Parameters
b the data.
off the start offset in the data.
len the number of bytes to write.
Throws
IOException if an I/O error occurs.

public abstract void write (byte[] b)

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

Parameters
b the data.
Throws
IOException if an I/O error occurs.

public abstract void write (int b)

Writes the specified byte to this session buffer.

Parameters
b the byte.
Throws
IOException if an I/O error occurs.

public abstract void writeLine (CharArrayBuffer buffer)

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

The choice of a char encoding and line delimiter sequence is up to the specific implementations of this interface.

Parameters
buffer the buffer containing chars of the line.
Throws
IOException if an I/O error occurs.

public abstract void writeLine (String s)

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

The choice of a char encoding and line delimiter sequence is up to the specific implementations of this interface.

Parameters
s the line.
Throws
IOException if an I/O error occurs.
