NAME

       HTML::FormFu::Filter - Filter Base Class

SYNOPSIS

	   ---
	   elements:
	     - type: Text
	       name: foo
	       filters:
		 - type: Encode
		   candidates:
		     - utf8

	       name: bar
	       filters:
		 - LowerCase
		 - Encode
	   filters:
	     - TrimEdges

DESCRIPTION

       "filters()" and "filter" can be called on any form, block element (includes fieldsets) or field element.

       If called on a field element, no "name" argument should be passed.

       If called on a form or block element, if no "name" argument is provided, a new filter is created for and added to every field on that form
       or block.

       See "FORM LOGIC AND VALIDATION" in HTML::FormFu for further details.

METHODS

   type
       Returns the "type" argument originally used to create the filter.

   localise_args
       Provide arguments that should be passed to localize to replace "[_1]", "[_2]", etc. in the localized string.

   parent
       Returns the HTML::FormFu::Element::_Field object that the filter is associated with.

   get_parent
       Arguments: \%options

       Traverses the parent hierarchy, returning the first parent that matches the supplied options.

   form
       Returns the HTML::FormFu object that the filter's field is attached to.

   name
       Shorthand for "$filter->parent->name"
