public class FeatureIdVersionedImpl extends FeatureIdImpl
Implementation ofFeatureId
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.

Method Detail
-
toString
public String toString()
Description copied from interface:Identifier
Returns a string representation of the identifier.- Specified by:
toString
in interfaceIdentifier
- Overrides:
toString
in classFeatureIdImpl
- 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 interfaceIdentifier
- Overrides:
equals
in classFeatureIdImpl
- 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 interfaceIdentifier
- Overrides:
hashCode
in classFeatureIdImpl
- 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 interfaceFeatureId
- Overrides:
equalsExact
in classFeatureIdImpl
- 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 interfaceFeatureId
- Overrides:
equalsFID
in classFeatureIdImpl
- 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, orgetID() + "@" + getFeatureVersion()
ifgetFeatureVersion() != 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 interfaceFeatureId
- Overrides:
getRid
in classFeatureIdImpl
- 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 interfaceFeatureId
- Overrides:
getPreviousRid
in classFeatureIdImpl
- Returns:
- Previous rid if available; or
null
-
getFeatureVersion
public String getFeatureVersion()
Description copied from interface:FeatureId
Version identifier for the feature instance, may benull
- Specified by:
getFeatureVersion
in interfaceFeatureId
- Overrides:
getFeatureVersion
in classFeatureIdImpl
- Returns:
- Optional version information;
null
if not available - See Also:
