Method Details

get

public Object get()
           throws org.apache.olingo.server.api.ODataApplicationException

Returns either an instance of an enumeration or an array of enumerations. This is sufficient for eq, ne and has operations, but will not work with any operation that requires a comparable like gt. As of now such operations are already blocked by Olingo in ExpressionParser.checkType().
In case in the future these operations shall be supported this method has to return an array of comparable, which goes with an incompatible change of annotation EdmEnumeration, as converters are required using such an array.
