NAME
Workflow::Base - Base class with constructor
SYNOPSIS
package My::App::Foo;
use base qw( Workflow::Base );
DESCRIPTION
Provide a constructor and some other useful methods for subclasses.
METHODS
Class Methods
new( @params )
Just create a new object (blessed hashref) and pass along @params
to the init()
method, which subclasses can override to initialize themselves.
Returns: new object
Object Methods
init( @params )
Subclasses may implement to do initialization. The @params
are whatever is passed into new()
. Nothing need be returned.
param( [ $name, $value ] )
Associate arbitrary parameters with this object.
If neither $name
nor $value
given, return a hashref of all parameters set in object:
my $params = $object->param();
while ( my ( $name, $value ) = each %{ $params } ) {
print "$name = $params->{ $name }\n";
}
If $name
given and it is a hash reference, assign all the values of the reference to the object parameters. This is the way to assign multiple parameters at once. Note that these will overwrite any existing parameter values. Return a hashref of all parameters set in object.
$object->param({ foo => 'bar',
baz => 'blarney' });
If $name
given and it is not a hash reference, return the value associated with it, undef
if $name
was not previously set.
my $value = $object->param( 'foo' );
print "Value of 'foo' is '$value'\n";
If $name
and $value
given, associate $name
with $value
, overwriting any existing value, and return the new value.
$object->param( foo => 'blurney' );
clear_params()
Clears out all parameters associated with this object.
normalize_array( \@array | $item )
If given \@array
return it dereferenced; if given $item
, return it in a list. If given neither return an empty list.
