  atg.repository.rql.RqlExpression

All Implemented Interfaces:

java.io.Serializable

public abstract class RqlExpression
extends java.lang.Object
implements java.io.Serializable

This is the base class for RQL expressions - expressions that are part of a query but cannot themselves be a query (because they do not necessarily evaluate to a boolean value).

createQueryExpression

public abstract QueryExpression createQueryExpression(QueryBuilder pBuilder,
                                                      RepositoryView pView,
                                                      java.lang.Object[] pParams)
                                               throws RepositoryException

This uses the specified query builder to construct the query expression corresponding to this instance. The parameters are substituted into the values of any ParameterExpressions.

Throws:

RepositoryException

createQueryExpression

public QueryExpression createQueryExpression(QueryBuilder pBuilder,
                                             RepositoryView pView,
                                             java.lang.Object[] pParams,
                                             boolean pCacheable)
                                      throws RepositoryException

This uses the specified query builder to construct the query expression corresponding to this instance. The parameters are substituted into the values of any ParameterExpressions. The boolean pCacheable is used to indicate that this parameter can or cannot perform certain optimizations

Throws:

RepositoryException
