NAME

       HTML::Widget::Accessor - Accessor Class

SYNOPSIS

	   use base 'HTML::Widget::Accessor';

DESCRIPTION

       Accessor Class.

METHODS

   attributes
   attrs
       Arguments: %attributes

       Arguments: \%attributes

       Return Value: $self

       Arguments: none

       Return Value: \%attributes

       Accepts either a list of key/value pairs, or a hash-ref.

	   $w->attributes( $key => $value );
	   $w->attributes( { $key => $value } );

       Returns the object reference, to allow method chaining.

       As of v1.10, passing a hash-ref no longer deletes current attributes, instead the attributes are added to the current attributes hash.

       This means the attributes hash-ref can no longer be emptied using "$w-"attributes( { } );>. Instead, you may use "%{ $w-"attributes } =
       ();>.

       As a special case, if no arguments are passed, the return value is a hash-ref of attributes instead of the object reference. This provides
       backwards compatibility to support:

	   $w->attributes->{key} = $value;

       "attrs" is an alias for "attributes".

   mk_attr_accessors
       Arguments: @names

       Return Value: @names
