Class OwnershipIndependentLatestConfigSpec

java.lang.Object
  wt.vc.config.OwnershipIndependentLatestConfigSpec

All Implemented Interfaces:

ConfigSpec, Externalizable, Serializable

public class OwnershipIndependentLatestConfigSpec

extends Object

implements ConfigSpec, Externalizable

This OwnershipIndependentLatestConfigSpec is similiar to the LatestConfigSpec, except that it does not take ownership into account. It simply returns the latest element regardless of ownership.

Supported API: true

Extendable: false

Method Summary

QuerySpec	appendSearchCriteria(QuerySpec querySpec) Appends a "latest = true" statement to the QuerySpec, indicating that only versions (latest iterations) should be considered.
QueryResult	process(QueryResult results) Returns the latest of the versions based on the version identifier (A.A is greater than A and B is greater than both, for example).
void	readExternal(ObjectInput input) Reads the non-transient fields of this class from an external source.
private boolean	readOldVersion(ObjectInput input, long readSerialVersionUID, boolean passThrough, boolean superDone) Reads the non-transient fields of this class from an external source, which is not the current version.
protected boolean	readVersion(OwnershipIndependentLatestConfigSpec thisObject, ObjectInput input, long readSerialVersionUID, boolean passThrough, boolean superDone) Reads the non-transient fields of this class from an external source.
void	writeExternal(ObjectOutput output) Writes the non-transient fields of this class to an external source.
