Constructor Details

SessionOutputBufferImpl

public SessionOutputBufferImpl(int buffersize,
 int lineBuffersize,
 CharsetEncoder charencoder,
 ByteBufferAllocator allocator)

Creates SessionOutputBufferImpl instance.

Parameters:

buffersize - input buffer size

lineBuffersize - buffer size for line operations. Has effect only if charencoder is not null.

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

allocator - memory allocator. If null HeapByteBufferAllocator.INSTANCE will be used.

Since:

4.3

Method Details

reset

public void reset(HttpParams params)

flush

public int flush(WritableByteChannel channel)
          throws IOException

Description copied from interface: SessionOutputBuffer

Makes an attempt to flush the content of this buffer to the given destination WritableByteChannel.

Specified by:

flush in interface SessionOutputBuffer

Parameters:

channel - the destination channel.

Returns:

The number of bytes written, possibly zero.

Throws:

IOException - in case of an I/O error.

write

public void write(ByteBuffer src)

Description copied from interface: SessionOutputBuffer

Copies content of the source buffer into this buffer. The capacity of the destination will be expanded in order to accommodate the entire content of the source buffer.

Specified by:

write in interface SessionOutputBuffer

Parameters:

src - the source buffer.

write

public void write(ReadableByteChannel src)
           throws IOException

Description copied from interface: SessionOutputBuffer

Reads a sequence of bytes from the source channel into this buffer.

Specified by:

write in interface SessionOutputBuffer

Parameters:

src - the source channel.

Throws:

IOException

writeLine

public void writeLine(CharArrayBuffer linebuffer)
               throws CharacterCodingException

Description copied from interface: SessionOutputBuffer

Copies content of the source buffer into this buffer as one line of text including a line delimiter. The capacity of the destination will be expanded in order to accommodate the entire content of the source buffer.

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

Specified by:

writeLine in interface SessionOutputBuffer

Parameters:

linebuffer - the source buffer.

Throws:

CharacterCodingException

writeLine

public void writeLine(String s)
               throws IOException

Description copied from interface: SessionOutputBuffer

Copies content of the given string into this buffer as one line of text including a line delimiter. The capacity of the destination will be expanded in order to accommodate the entire string.

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

Specified by:

writeLine in interface SessionOutputBuffer

Parameters:

s - the string.

Throws:

IOException
