NAME

       POE::Resource::Sessions - internal session manager for POE::Kernel

SYNOPSIS

       There is no public API.

DESCRIPTION

       POE::Resource::Sessions is a mix-in class for POE::Kernel.  It provides the internal features that manage sessions, regardless of the
       session type.  It is used internally by POE::Kernel. so it has no public interface.

SEE ALSO

       See POE::Session and POE::NFA for one type of session.  CPAN also have others.

       See "Sessions" in POE::Kernel for a discussion about POE::Kernel sessions.

       See "Session Lifespans" in POE::Kernel to learn why sessions run, and how to stop them.

       See "Session Management" in POE::Kernel for information about managing sessions in your applications, and the events that occur when
       sessions come and go.

       See "Session Helper Methods" in POE::Kernel for friend methods between POE::Kernel and POE::Session classes.

       See "Resources" in POE::Kernel for for public information about POE resources.

       See POE::Resource for general discussion about resources and the classes that manage them.

BUGS

       None known.

NAME

       POE::Driver::SysRW - buffered, non-blocking I/O using sysread and syswrite

SYNOPSIS

       "SYNOPSIS" in POE::Driver illustrates how the interface works.  This module is merely one implementation.

DESCRIPTION

       This driver implements POE::Driver using sysread and syswrite.

PUBLIC METHODS

       POE::Driver::SysRW introduces some additional features not covered in the base interface.

   new [BlockSize => OCTETS]
       new() creates a new buffered I/O driver that uses sysread() to read data from a handle and syswrite() to flush data to that handle.  The
       constructor accepts one optional named parameter, "BlockSize", which indicates the maximum number of OCTETS that will be read at one time.

       "BlockSize" is 64 kilobytes (65536 octets) by default.  Higher values may improve performance in streaming applications, but the trade-off
       is a lower event granularity and increased resident memory usage.

       Lower "BlockSize" values reduce memory consumption somewhat with corresponding throughput penalties.

	 my $driver = POE::Driver::SysRW->new;

	 my $driver = POE::Driver::SysRW->new( BlockSize => $block_size );

       Drivers are commonly instantiated within POE::Wheel constructor calls:

	 $_[HEAP]{wheel} = POE::Wheel::ReadWrite->new(
	   InputHandle => *STDIN,
	   OutputHandle => *STDOUT,
	   Driver => POE::Driver::SysRW->new(),
	   Filter => POE::Filter::Line->new(),
	 );

       Applications almost always use POE::Driver::SysRW, so POE::Wheel objects almost always will create their own if no Driver is specified.

   All Other Methods
       POE::Driver::SysRW documents the abstract interface documented in POE::Driver.  Please see POE::Driver for more details about the following
       methods:

       flush
       get
       get_out_messages_buffered
       put
