public class ResourceIdImpl
extends FeatureIdVersionedImpl
implements ResourceId

Implementation of ResourceId used for Query.

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.

ResourceIdImpl(String fid, String featureVersion)
          Obtain a ResourceId that represents an explicit request for feature id and feature version (essentially the quivalent of FeatureId)
ResourceIdImpl(String fid, String featureVersion, Version version)
          Obtain a ResourceId based on version lookup.

Constructor Detail

ResourceIdImpl

public ResourceIdImpl(String fid,
                      String featureVersion,
                      Version version)
Obtain a ResourceId based on version lookup.

Parameters:
fid - feature being queried
featureVersion - version used as a reference point
version - scope of version based query (first, last, index, all, date, etc...)

ResourceIdImpl

public ResourceIdImpl(String fid,
                      String featureVersion)
Obtain a ResourceId that represents an explicit request for feature id and feature version (essentially the quivalent of FeatureId)

Parameters:
fid -
featureVersion -

ResourceIdImpl

public ResourceIdImpl(String fid,
                      Date start,
                      Date end)
Date range constructor for a feature id; none or one of start and end can be null, making for an unconstrained date range at either of the ends.

Parameters:
fid - feature id, non null;
start - lower end of the time range, inclusive, or null only if end != null
start - upper end of the time range, inclusive, or null only if start != null
Method Detail

setRid

public void setRid(String rid)

setPreviousRid

public void setPreviousRid(String previousRid)

setVersion

public void setVersion(Version version)

getStartTime

public Date getStartTime()
Description copied from interface: ResourceId
Used to select versions of a resource between start and end time.

Specified by:
getStartTime in interface ResourceId
Returns:
start time for a time based query; or null if using version or an end time was provided but the start time is unconstrained TODO: consider using an org.geotools.util.Range instead of both start and end time?

setStartTime

public void setStartTime(Date startTime)

getEndTime

public Date getEndTime()
Description copied from interface: ResourceId
Used to select versions of a resource between start and end time.

Specified by:
getEndTime in interface ResourceId
Returns:
end time for a time based query; or null if using version or an start time was provided but the end time is unconstrained TODO: consider using an org.geotools.util.Range instead of both start and end time?

setEndTime

public void setEndTime(Date endTime)

getVersion

public Version getVersion()
Description copied from interface: ResourceId
Used to navigate versions of a resource.

Specified by:
getVersion in interface ResourceId
Returns:
Version based resource query; non null but possibly empty if used a date range query or asked for a specific feature id + version id

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 FeatureIdVersionedImpl
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 FeatureIdVersionedImpl
Returns:
hashCode based on getID()
