/**

* Declares how a type converts to and from a scalar, by naming the methods the mapper calls.

*

* <p>Each attribute is one decode and encode pair, and the attribute is repeatable. On read, the pair whose

* decode parameter type accepts the source scalar is used, so a type can be built from more than one scalar

* form. On write, the first declared pair's encode is used. A registered mapping for the same type takes

* precedence over this attribute.</p>

*

* <p>The decode method is a public static factory that builds the type from the scalar, and the encode method

* a public instance method that reduces the type back to a scalar.</p>

*

* @see Codec for the registered, closure-based equivalent.
