NAME

6       "Future::IO::ImplBase" - base class for "Future::IO" implementations
7

DESCRIPTION

9       This package provides a few utility methods that may help writing
10       actual Future::IO implementation classes. It is entirely optional;
11       implementations are not required to use it.
12

CLASS METHODS

14   APPLY
15          __PACKAGE__->APPLY
16
17       Attempts to set the value of the $Future::IO::IMPL variable to the name
18       of the calling package.

DEFAULT METHODS

21       These methods are provided based on lower-level functionallity that the
22       implementing class should provide.
23
24   sysread
25       Requires a lower-level method
26
27          $f = $class->ready_for_read( $fh )
28
29       which should return a Future that completes when the given filehandle
30       may be ready for reading.
31
32   syswrite
33       Requires a lower-level method
34
35          $f = $class->ready_for_write( $fh )
36
37       which should return a Future that completes when the given filehandle
