Method Details

getExpressions

public abstract List<Expression<Boolean>> getExpressions()

Description copied from interface: Predicate

Return the top-level conjuncts or disjuncts of the predicate. Returns empty list if there are no top-level conjuncts or disjuncts of the predicate.

Specified by:

getExpressions in interface Predicate

Returns:

list of boolean expressions forming the predicate

getOperator

public Predicate.BooleanOperator getOperator()

Description copied from interface: Predicate

Return the boolean operator for the predicate. If the predicate is simple, this is AND.

Specified by:

getOperator in interface Predicate

Returns:

boolean operator for the predicate

setExpressionToQuery

public abstract void setExpressionToQuery(StringBuilder query,
 CriteriaParameterFiller parameterFiller)

Specified by:

setExpressionToQuery in class AbstractExpression<Boolean>

negateOperator

protected void negateOperator()
