NAME
Class::Accessor::Grouped - Lets you build groups of accessorsSYNOPSIS
DESCRIPTION
This class lets you build groups of accessors that will call different getters and setters.METHODS
mk_group_accessors
- Arguments: $group, @fieldspec
- Returns: none
Creates a set of accessors in a given group.
$group is the name of the accessor group for the generated accessors; they will call get_$group($field) on get and set_$group($field, $value) on set.
If you want to mimic Class::Accessor's mk_accessors $group has to be 'simple' to tell Class::Accessor::Grouped to use its own get_simple and set_simple methods.
@fieldspec is a list of field/accessor names; if a fieldspec is a scalar this is used as both field and accessor name, if a listref it is expected to be of the form [ $accessor, $field ].
mk_group_ro_accessors
- Arguments: $group, @fieldspec
- Returns: none
Creates a set of read only accessors in a given group. Identical to ``mk_group_accessors'' but accessors will throw an error if passed a value rather than setting the value.
mk_group_wo_accessors
- Arguments: $group, @fieldspec
- Returns: none
Creates a set of write only accessors in a given group. Identical to ``mk_group_accessors'' but accessors will throw an error if not passed a value rather than getting the value.
make_group_accessor
- Arguments: $group, $field
- Returns: $sub (\CODE)
Returns a single accessor in a given group; called by mk_group_accessors for each entry in @fieldspec.
make_group_ro_accessor
- Arguments: $group, $field
- Returns: $sub (\CODE)
Returns a single read-only accessor in a given group; called by mk_group_ro_accessors for each entry in @fieldspec.
make_group_wo_accessor
- Arguments: $group, $field
- Returns: $sub (\CODE)
Returns a single write-only accessor in a given group; called by mk_group_wo_accessors for each entry in @fieldspec.
get_simple
- Arguments: $field
- Returns: $value
Simple getter for hash-based objects which returns the value for the field name passed as an argument.
set_simple
- Arguments: $field, $new_value
- Returns: $new_value
Simple setter for hash-based objects which sets and then returns the value for the field name passed as an argument.
get_inherited
- Arguments: $field
- Returns: $value
Simple getter for Classes and hash-based objects which returns the value for the field name passed as an argument. This behaves much like Class::Data::Accessor where the field can be set in a base class, inherited and changed in subclasses, and inherited and changed for object instances.
set_inherited
- Arguments: $field, $new_value
- Returns: $new_value
Simple setter for Classes and hash-based objects which sets and then returns the value for the field name passed as an argument. When called on a hash-based object it will set the appropriate hash key value. When called on a class, it will set a class level variable.
Note:: This method will die if you try to set an object variable on a non hash-based object.
get_component_class
- Arguments: $field
- Returns: $value
Gets the value of the specified component class.
__PACKAGE__->mk_group_accessors('component_class' => 'result_class'); $self->result_class->method(); ## same as $self->get_component_class('result_class')->method();
set_component_class
- Arguments: $field, $class
- Returns: $new_value
Inherited accessor that automatically loads the specified class before setting it. This method will die if the specified class could not be loaded.
__PACKAGE__->mk_group_accessors('component_class' => 'result_class'); __PACKAGE__->result_class('MyClass'); $self->result_class->method();
get_super_paths
Returns a list of 'parent' or 'super' class names that the current class inherited from.AUTHORS
