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.
