Class FeatureIdImpl

Object
FeatureIdImpl
All Implemented Interfaces:
FeatureId, Identifier
Direct Known Subclasses:
FeatureIdVersionedImpl
public class FeatureIdImpl extends Object implements FeatureId
Implementation of FeatureId

This class is mutable under one condition only; during a commit a datastore can update the internal fid to reflect the real identify assigned by the database or wfs.

      public String getID()
      Description copied from interface: FeatureId
      The identifier value, which is a string.
      Specified by:
      getID in interface FeatureId
      Specified by:
      getID in interface Identifier

      public boolean matches(Feature feature)

    • matches

      public boolean matches(Object object)
      Description copied from interface: FeatureId
      Evaluates the identifer value against the given feature.
      Specified by:
      matches in interface FeatureId
      Specified by:
      matches in interface Identifier
      Parameters:
      object - The feature to be tested.
      Returns:

    • toString

      public String toString()
      Description copied from interface: Identifier
      Returns a string representation of the identifier.
      Specified by:
      toString in interface Identifier
      Overrides:
      toString in class Object
      Returns:
      getID().toString()

    • equals

      public boolean equals(Object obj)
      Description copied from interface: Identifier
      Identifier is a data object, equals is based just on getID()
      Specified by:
      equals in interface Identifier
      Overrides:
      equals in class Object
      Returns:
      true if obj is an Identifier with the same getID()

    • hashCode

      public int hashCode()
      Description copied from interface: Identifier
      Identifier is a data object, hashCode is based just on getID()
      Specified by:
      hashCode in interface Identifier
      Overrides:
      hashCode in class Object
      Returns:
      hashCode based on getID()

    • equalsExact

      public boolean equalsExact(FeatureId id)
      Description copied from interface: FeatureId
      Check if the provided FeatureId is an exact match (including any optional version information).
      Specified by:
      equalsExact in interface FeatureId
      Returns:
      true if this is an exact match (including any optional version information)

    • equalsFID

      public boolean equalsFID(FeatureId id)
      Description copied from interface: FeatureId
      Checks if the provided FeatureId reflects the same feature.

      This comparison does not compare any optional version information.

      Specified by:
      equalsFID in interface FeatureId
      Returns:
      true if both identifiers describe the same feature (does not compare version information).

    • getRid

      public String getRid()
      Description copied from interface: FeatureId
      id of the resource that shall be selected by the predicate.

      Equals to FeatureId.getID() if no feature version is provided, or getID() + "@" + getFeatureVersion() if getFeatureVersion() != null

      If an implementation that references this International Standard supports versioning, the rid shall be a system generated hash containing a logical resource identifier and a version number. The specific details of the hash are implementation dependant and shall be opaque to a client

      If versioning is not supported, the same value than FeatureId.getID() shall be returned.

      Specified by:
      getRid in interface FeatureId
      Returns:
      Resource identifier made up of FID (combined with FeatureVersion if available)

    • getPreviousRid

      public String getPreviousRid()
      Description copied from interface: FeatureId
      previousRid attribute may be used, in implementations that support versioning, to report the previous identifier of a resource.
      Specified by:
      getPreviousRid in interface FeatureId
      Returns:
      Previous rid if available; or null

    • getFeatureVersion

      public String getFeatureVersion()
      Description copied from interface: FeatureId
      Version identifier for the feature instance, may be null
      Specified by:
      getFeatureVersion in interface FeatureId
      Returns:
      Optional version information; null if not available
