NAME

Future::IO::ImplBase - base class for Future::IO implementations

DESCRIPTION

This package provides a few utility methods that may help writing actual Future::IO implementation classes. It is entirely optional; implementations are not required to use it.

CLASS METHODS

APPLY

   __PACKAGE__->APPLY

Attempts to set the value of the $Future::IO::IMPL variable to the name of the calling package.

DEFAULT METHODS

These methods are provided based on lower-level functionallity that the implementing class should provide.

accept

Implemented by wrapping ready_for_read, as "sysread" uses.

alarm

Implemented by wrapping sleep.

connect

Implemented by wrapping ready_for_write, as "syswrite" uses.

sysread

Requires a lower-level method

   $f = $class->ready_for_read( $fh )

which should return a Future that completes when the given filehandle may be ready for reading.

syswrite

Requires a lower-level method

   $f = $class->ready_for_write( $fh )

which should return a Future that completes when the given filehandle may be ready for writing.
