Constructor Detail

SqmComparisonPredicate

public SqmComparisonPredicate(SqmExpression<?> leftHandExpression,
                              ComparisonOperator operator,
                              SqmExpression<?> rightHandExpression,
                              NodeBuilder nodeBuilder)

Method Detail

copy

public SqmComparisonPredicate copy(SqmCopyContext context)

getLeftHandExpression

public SqmExpression<?> getLeftHandExpression()

getRightHandExpression

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:

createNegatedNode in class AbstractNegatableSqmPredicate

accept

public <T> T accept(SemanticQueryWalker<T> walker)

Description copied from interface: SqmVisitableNode

Accept the walker per visitation

appendHqlString

public void appendHqlString(StringBuilder sb)
