Enum FoliationRepresentation

  • All Implemented Interfaces:
    Serializable, Comparable<Foliation­Representation>
    public enum FoliationRepresentation
extends Enum<FoliationRepresentation>
    Specifies whether trajectories are represented in a single moving feature instance or fragmented in distinct static feature instances.
    Example: consider the following trajectories:
    Moving features example
    Identifier Time Trajectory Status
    John Smith 8:00 (3 4), (3 5) Walking
    Joe Blo 8:00 (5 5), (6 6) Walking
    John Smith 8:05 (3 5), (3 9) Running
    In this example, John Smith's trajectory can be represented in two ways: we can construct a single moving feature instance representing the full trajectory (3 4), (3 5), (3 9) with some time representation (for example by adding a temporal dimension in each coordinate) and dynamic "Status" property. Or alternatively, we can keep John Smith's trajectory fragmented in two Feature instance where each instance can be handled as a static feature.
    This enumeration can be used with Data­Store as a hint about desired representation of moving features.

    • Enum Constant Detail

      • ASSEMBLED

        public static final FoliationRepresentation ASSEMBLED
        Trajectories stored in a single Feature instance. Every point on the trajectory may be at a different time. Properties may be dynamic, i.e. have time-dependent value.

      • FRAGMENTED

        public static final FoliationRepresentation FRAGMENTED
        Trajectories stored in distinct Feature instances, each of them handled as if it was a static feature.

    • Method Detail

      • values

        public static FoliationRepresentation[] values()
        Returns an array containing the constants of this enum type, in the order they are declared. This method may be used to iterate over the constants as follows: 
        for (FoliationRepresentation c : FoliationRepresentation.values())
    System.out.println(c);
        Returns:
        an array containing the constants of this enum type, in the order they are declared

      • valueOf

        public static FoliationRepresentation valueOf​(String name)
        Returns the enum constant of this type with the specified name. The string must match exactly an identifier used to declare an enum constant in this type. (Extraneous whitespace characters are not permitted.)
        Parameters:
        name - the name of the enum constant to be returned.
        Returns:
        the enum constant with the specified name
        Throws:
        Illegal­Argument­Exception - if this enum type has no constant with the specified name
        Null­Pointer­Exception - if the argument is null
