7

VERSION

9       This documentation describes version 1.08 of this package
10

SYNOPSIS

12        package My::App::Foo;
13        use base qw( Workflow::Base );
14

DESCRIPTION

16       Provide a constructor and some other useful methods for subclasses.
17

METHODS

19   Class Methods
20       new( @params )
21
22       Just create a new object (blessed hashref) and pass along @params to
23       the "init()" method, which subclasses can override to initialize
24       themselves.
25
26       Returns: new object
27
28   Object Methods
29       init( @params )
30
31       Subclasses may implement to do initialization. The @params are whatever
32       is passed into "new()". Nothing need be returned.
33
34       param( [ $name, $value ] )
35
36       Associate arbitrary parameters with this object.
37
38       If neither $name nor $value given, return a hashref of all parameters
39       set in object:
40
41        my $params = $object->param();
42        while ( my ( $name, $value ) = each %{ $params } ) {
43            print "$name = $params->{ $name }\n";
44        }
45
46       If $name given and it is a hash reference, assign all the values of the
47       reference to the object parameters. This is the way to assign multiple
48       parameters at once. Note that these will overwrite any existing
49       parameter values. Return a hashref of all parameters set in object.
50
51        $object->param({ foo => 'bar',
52                         baz => 'blarney' });
53
54       If $name given and it is not a hash reference, return the value
55       associated with it, "undef" if $name was not previously set.
56
57        my $value = $object->param( 'foo' );
58        print "Value of 'foo' is '$value'\n";
59
60       If $name and $value given, associate $name with $value, overwriting any
61       existing value, and return the new value.
62
63        $object->param( foo => 'blurney' );
64
65       delete_param( [ $name ] )
66
67       Delete parameters from this object.
68
69       If $name given and it is an array reference, then delete all parameters
70       from this object. All deleted parameters will be returned as a hash
71       reference together with their values.
72
73        my $deleted = $object->delete_param(['foo','baz']);
74        foreach my $key (keys %{$deleted})
75        {
76          print $key."::=".$deleted->{$key}."\n";
77        }
78
79       If $name given and it is not an array reference, delete the parameter
80       and return the value of the parameter.
81
82        my $value = $object->delete_param( 'foo' );
83        print "Value of 'foo' was '$value'\n";
84
85       If $name is not defined or $name does not exists the undef is returned.
86
87       clear_params()
88
89       Clears out all parameters associated with this object.
90
91       normalize_array( \@array | $item )
92
93       If given "\@array" return it dereferenced; if given $item, return it in
94       a list. If given neither return an empty list.
