Class AbstractPositionalAccuracy

All Implemented Interfaces:
Serializable, Emptiable, Lenient­Comparable, Identified­Object, Element, Positional­Accuracy
Direct Known Subclasses:
Default­Absolute­External­Positional­Accuracy, Default­Gridded­Data­Positional­Accuracy, Default­Relative­Internal­Positional­Accuracy

public class AbstractPositionalAccuracy extends AbstractElement implements PositionalAccuracy
Accuracy of the position of features. The following property is mandatory in a well-formed metadata according ISO 19115:
DQ_Positional­Accuracy   └─result…………… Value obtained from applying a data quality measure.


  • Instances of this class are not synchronized for multi-threading. Synchronization, if needed, is caller's responsibility.
  • Serialized objects of this class are not guaranteed to be compatible with future Apache SIS releases. Serialization support is appropriate for short term storage or RMI between applications running the same version of Apache SIS. For long term storage, use XML instead.

  • Constructor Details

    • AbstractPositionalAccuracy

      public AbstractPositionalAccuracy()
      Constructs an initially empty positional accuracy.
    • AbstractPositionalAccuracy

      public AbstractPositionalAccuracy(Result result)
      Creates an positional accuracy initialized to the given result.
      result - the value obtained from applying a data quality measure against a specified acceptable conformance quality level.
    • AbstractPositionalAccuracy

      public AbstractPositionalAccuracy(PositionalAccuracy object)
      Constructs a new instance initialized with the values from the specified metadata object. This is a shallow copy constructor, since the other metadata contained in the given object are not recursively copied.
      object - the metadata to copy values from, or null if none.

    • castOrCopy

      public static AbstractPositionalAccuracy castOrCopy(PositionalAccuracy object)
      Returns a SIS metadata implementation with the values of the given arbitrary implementation. This method performs the first applicable action in the following choices:
      • If the given object is null, then this method returns null.
      • Otherwise if the given object is an instance of Relative­Internal­Positional­Accuracy, Absolute­External­Positional­Accuracy or Gridded­Data­Positional­Accuracy, then this method delegates to the cast­Or­Copy(…) method of the corresponding SIS subclass. Note that if the given object implements more than one of the above-cited interfaces, then the cast­Or­Copy(…) method to be used is unspecified.
      • Otherwise if the given object is already an instance of Abstract­Positional­Accuracy, then it is returned unchanged.
      • Otherwise a new Abstract­Positional­Accuracy instance is created using the copy constructor and returned. Note that this is a shallow copy operation, since the other metadata contained in the given object are not recursively copied.
      object - the object to get as a SIS implementation, or null if none.
      a SIS implementation containing the values of the given object (may be the given object itself), or null if the argument was null.
