For example, a Rational® ClearQuest record is mapped to an instance of the CqRecord interface. The CqRecord interface is an extension (defined in com.ibm.rational.wvcm.stp.cq) of the StpResource interface (defined in com.ibm.rational.wvcm.stp), which, itself is an extension of the WVCM Resource interface. The Resource interface provides the standard mechanisms to retrieve the properties (for example, Name and Description) and content of a resource, including its relationships to other resource types (for example, from a record to a field).
