Member

class Member<T>

A member that contributes JSON. Typically, a member will contribute a single name/value pair based on an extracted value. They may also contribute more complex JSON structures when configured with one of the using(...) methods.

The when(...) methods may be used to filter a member (omit it entirely from the JSON). The as method can be used to adapt to a different type.

Parameters

<T>

the member type
