Enum FoliationRepresentation

java.lang.Object
java.lang.Enum<FoliationRepresentation>
org.apache.sis.feature.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 Details

    • 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 Details

    • values

      public static FoliationRepresentation[] values()
      Returns an array containing the constants of this enum type, in the order they are declared.
      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
