public SqmExpression<?> getRightHandExpression()

getSqmOperator

public ComparisonOperator getSqmOperator()

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

Overrides:

negate in class AbstractNegatableSqmPredicate

createNegatedNode

protected SqmNegatablePredicate createNegatedNode()

Specified by:

accept

Description copied from interface: SqmVisitableNode

Accept the walker per visitation

equals

public boolean equals(@Nullable Object object)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:
