NAME

       "Object::Pad::MOP::Field" - meta-object representation of data field of a "Object::Pad" class

DESCRIPTION

       Instances of this class represent a data field of a class implemented by Object::Pad. Accessors provide
       information about the field. The special "value" method allows access to the value of the given field on
       instances of its class, letting the meta-object be used as a proxy to it.

       This API should be considered experimental even within the overall context in which "Object::Pad" is
       expermental.

METHODS

   name
          $name = $metafield->name

       Returns the name of the field, as a plain string including the leading sigil character.

   sigil
          $sigil = $metafield->sigil

       Since version 0.56.

       Returns the first character of the field name, giving just its leading sigil.

   class
          $metaclass = $metafield->class

       Returns the Object::Pad::MOP::Class instance representing the class of which this field is a member.

   value
          $current = $metafield->value( $instance )
          @current = $metafield->value( $instance )
          %current = $metafield->value( $instance )

       An accessor method which returns the current value of the field from an object instance.

          $metafield->value( $instance ) = $new

       On scalar fields, this method can also act as an lvalue mutator allowing a new value to be set.

   has_attribute
          $exists = $metafield->has_attribute( $name )

       Since version 0.57.

       Returns a boolean indicating whether the named attribute has been attached to the field. The attribute
       name should not include the leading colon (":") character.

   get_attribute_value
          $value = $metafield->get_attribute_value( $name )

       Since version 0.57.

       Returns the stored value of an attached attribute, if one exists. If the attribute has not been attached
       then an exception is thrown.

       Note that most core-defined attributes will either store no data at all, or a method name string. This
       accessor method is provided largely for the benefit of obtaining data defined by third-party attributes,
       which may more clearly define how that data is generated and used.
