PropertyMap

class PropertyMap extends DataMap

A PropertyMap stores aggregated properties of the entity. Internally it is a Map whose keys are property names and values are corresponding JSON values respectively. Use the get() method to retrieve the value of mandatory property or use getOpt() to retrieve the value of the optional property.
