Interface SessionOutputBuffer

All Known Implementing Classes:

SessionOutputBufferImpl

public interface SessionOutputBuffer

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.

Since:

4.0

Method Summary

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

Method Detail

write

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

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:

java.io.IOException - if an I/O error occurs.

write

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

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

Parameters:

b - the data.

Throws:

java.io.IOException - if an I/O error occurs.

write

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

Writes the specified byte to this session buffer.

Parameters:

b - the byte.

Throws:

java.io.IOException - if an I/O error occurs.

writeLine

void writeLine(java.lang.String s)
        throws java.io.IOException

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:

java.io.IOException - if an I/O error occurs.

writeLine

void writeLine(CharArrayBuffer buffer)
        throws java.io.IOException

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:

java.io.IOException - if an I/O error occurs.

flush

void flush()
    throws java.io.IOException

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:

java.io.IOException - if an I/O error occurs.

getMetrics

HttpTransportMetrics getMetrics()

Returns HttpTransportMetrics for this session buffer.

Returns:

transport metrics.
