Parameters:
operand - the operand whose value is converted to a lower-case string; non-null
Returns:
the operand; non-null
Throws:
InvalidQueryException - if a particular validity test is possible on this method, the implemention chooses to perform that test (and not leave it until later, on createQuery(javax.jcr.query.qom.Source, javax.jcr.query.qom.Constraint, javax.jcr.query.qom.Ordering[], javax.jcr.query.qom.Column[])), and the parameters given fail that test
RepositoryException - if the operation otherwise fails

upperCase

                           RepositoryException
Evaluates to the upper-case string value (or values, if multi-valued) of an operand.

Parameters:
operand - the operand whose value is converted to a upper-case string; non-null
Returns:
the operand; non-null
Throws:
InvalidQueryException - if a particular validity test is possible on this method, the implemention chooses to perform that test (and not leave it until later, on createQuery(javax.jcr.query.qom.Source, javax.jcr.query.qom.Constraint, javax.jcr.query.qom.Ordering[], javax.jcr.query.qom.Column[])), and the parameters given fail that test
RepositoryException - if the operation otherwise fails

bindVariable

BindVariableValue bindVariable(java.lang.String bindVariableName)
                               throws InvalidQueryException,
                                      RepositoryException
Evaluates to the value of a bind variable.

The query is invalid if bindVariableName is not a valid JCR prefix.

Parameters:
bindVariableName - the bind variable name; non-null
Returns:
the operand; non-null
Throws:
InvalidQueryException - if a particular validity test is possible on this method, the implemention chooses to perform that test (and not leave it until later, on createQuery(javax.jcr.query.qom.Source, javax.jcr.query.qom.Constraint, javax.jcr.query.qom.Ordering[], javax.jcr.query.qom.Column[])), and the parameters given fail that test.
RepositoryException - if the operation otherwise fails

literal

Literal literal(Value literalValue)
                throws InvalidQueryException,
                       RepositoryException
Evaluates to a literal value.

Parameters:
literalValue - the value
Returns:
the literal; non-null
Throws:
InvalidQueryException - if a particular validity test is possible on this method, the implemention chooses to perform that test (and not leave it until later, on createQuery(javax.jcr.query.qom.Source, javax.jcr.query.qom.Constraint, javax.jcr.query.qom.Ordering[], javax.jcr.query.qom.Column[])), and the parameter given fails that test
RepositoryException - if the operation otherwise fails

ascending

Ordering ascending(DynamicOperand operand)
                   throws InvalidQueryException,
                          RepositoryException
Orders by the value of the specified operand, in ascending order. The query is invalid if operand does not evaluate to a scalar value.

Parameters:
operand - the operand by which to order; non-null
Returns:
the ordering
Throws:
InvalidQueryException - if a particular validity test is possible on this method, the implemention chooses to perform that test (and not leave it until later, on createQuery(javax.jcr.query.qom.Source, javax.jcr.query.qom.Constraint, javax.jcr.query.qom.Ordering[], javax.jcr.query.qom.Column[])), and the parameters given fail that test
RepositoryException - if the operation otherwise fails

descending

Ordering descending(DynamicOperand operand)
                    throws InvalidQueryException,
                           RepositoryException
Orders by the value of the specified operand, in descending order. The query is invalid if operand does not evaluate to a scalar value.

Parameters:
operand - the operand by which to order; non-null
Returns:
the ordering
Throws:
InvalidQueryException - if a particular validity test is possible on this method, the implemention chooses to perform that test (and not leave it until later, on createQuery(javax.jcr.query.qom.Source, javax.jcr.query.qom.Constraint, javax.jcr.query.qom.Ordering[], javax.jcr.query.qom.Column[])), and the parameters given fail that test
RepositoryException - if the operation otherwise fails

column

Column column(java.lang.String selectorName,
              java.lang.String propertyName,
              java.lang.String columnName)
              throws InvalidQueryException,
                     RepositoryException
Identifies a property in the specified selector to include in the tabular view of query results.

The query is invalid if:

If propertyName is specified but, for a node-tuple, the selector node does not have a property named propertyName, the query is valid and the column has null value.

Parameters:
selectorName - the selector name; non-null
propertyName - the property name, or null to include a column for each single-value non-residual property of the selector's node type
columnName - the column name; must be null if propertyName is null; must be non-null if propertyName is non-null.
Returns:
the column; non-null
Throws:
InvalidQueryException - if a particular validity test is possible on this method, the implemention chooses to perform that test (and not leave it until later, on createQuery(javax.jcr.query.qom.Source, javax.jcr.query.qom.Constraint, javax.jcr.query.qom.Ordering[], javax.jcr.query.qom.Column[])), and the parameters given fail that test
RepositoryException - if the operation otherwise fails
