public class FeatureIdVersionedImpl
extends FeatureIdImpl

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.

Constructor Detail

FeatureIdVersionedImpl

public FeatureIdVersionedImpl(String fid,
                              String version)

FeatureIdVersionedImpl

public FeatureIdVersionedImpl(String fid,
                              String version,
                              String previousRid)
Method Detail

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 FeatureIdImpl
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 FeatureIdImpl
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 FeatureIdImpl
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
Overrides:
equalsExact in class FeatureIdImpl
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
Overrides:
equalsFID in class FeatureIdImpl
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
Overrides:
getRid in class FeatureIdImpl
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
Overrides:
getPreviousRid in class FeatureIdImpl
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
Overrides:
getFeatureVersion in class FeatureIdImpl
Returns:
Optional version information; null if not available
