Serializable

public class DynaProperty extends Object implements Serializable

The metadata describing an individual property of a DynaBean.

The meta contains an optional content type property (getContentType()) for use by mapped and iterated properties. A mapped or iterated property may choose to indicate the type it expects. The DynaBean implementation may choose to enforce this type on its entries. Alternatively, an implementatin may choose to ignore this property. All keys for maps must be of type String so no meta data is needed for map keys.
