                       HttpTransportMetricsImpl metrics)
Method Detail

write

public int write(java.nio.ByteBuffer src)
          throws java.io.IOException
Description copied from interface: ContentEncoder
Writes a portion of entity content to the underlying channel.

Specified by:
write in interface ContentEncoder
Parameters:
src - The buffer from which content is to be retrieved
Returns:
The number of bytes read, possibly zero
Throws:
java.io.IOException - if I/O error occurs while writing content

Description copied from interface: FileContentEncoder
Transfers a portion of entity content from the given file channel to the underlying network channel.

Specified by:
transfer in interface FileContentEncoder
Parameters:
src - the source FileChannel to transfer data from.
position - The position within the file at which the transfer is to begin; must be non-negative
count - The maximum number of bytes to be transferred; must be non-negative
Returns:
The number of bytes, possibly zero, that were actually transferred
Throws:
