# LuaField Methods

This section describes the methods provided by `LuaField` objects. A `LuaField` represents a single field in a document. You can retrieve `LuaField` objects for a document using the `LuaDocument` `getField` and `getFields` methods. In its simplest form a field has just a name and a value, but it can also contain sub-fields.

If you have a `LuaField` object called `field` you can call its methods using the '`:`' operator. For example:

    field:addField(name, value)
