NAME

6       Promises::Promise - An implementation of Promises in Perl
7

VERSION

9       version 1.04
10

DESCRIPTION

12       Promise objects are typically not created by hand, they are typically
13       returned from the "promise" method of a Promises::Deferred instance. It
14       is best to think of a Promises::Promise instance as a handle for
15       Promises::Deferred instances.
16
17       Most of the documentation here points back to the documentation in the
18       Promises::Deferred module.
19
20       Additionally Promises::Cookbook::GentleIntro contains a long
21       explanation of how this module, and all its components are meant to
22       work together.

METHODS

25       "new( $deferred )"
26           The constructor only takes one parameter and that is an instance of

28
29       "then( $callback, $error )"
30           This calls "then" on the proxied Promises::Deferred instance.
31
32       "chain( @thens )"
33           This calls "chain" on the proxied Promises::Deferred instance.
34
35       "catch( $error )"
36           This calls "catch" on the proxied Promises::Deferred instance.
37
38       "done( $callback, $error )"
39           This calls "done" on the proxied Promises::Deferred instance.
40
41       "finally( $callback )"
42           This calls "finally" on the proxied Promises::Deferred instance.
43
44       "timeout( $seconds )"
