Class JQLC

java.lang.Object

com.sun.jdo.spi.persistence.support.sqlstore.query.jqlc.JQLC

public class JQLC
extends Object

Version:

0.1 Note: this class allows to override its fields even after all the processing is done via the corresponding setXXX methods. This is not expected behavior. A better solution would be to change all setters to be private and have use a constructor to populate all the values. The constructor will call private setters to process the arguments.

retrieveDescCache

protected Map retrieveDescCache

RD cache, key is a string build from actual param values (see ParameterTable.getKeyForRetrieveDescCache). It's ok to use WeakHashMap from java.util, because the key is a string which is not referenced by the RD.
