Method Details

isNegated

public boolean isNegated()

Description copied from interface: SqmNegatablePredicate

Is this predicate (currently) negated?

Specified by:

isNegated in interface Predicate

Specified by:

isNegated in interface SqmNegatablePredicate

Returns:

true if we have a negated form currently

negate

public void negate()

Description copied from interface: SqmNegatablePredicate

Apply an external negation. Called when we encounter a NOT grouping.

For example, for not(x is null) we build the SqmNullnessPredicate and then call its negate method which results in x is not null.

Can be applied nested as well. For example, not(not(x is null)) becomes x is null because the double-negative cancel each other out.

Specified by:

negate in interface SqmNegatablePredicate

createNegatedNode

protected abstract SqmNegatablePredicate createNegatedNode()

not

@Nonnull
public SqmNegatablePredicate not()

Specified by:

Specified by:

not in interface SqmBooleanExpressionImplementor
