Method Detail

getCurrentClauseStack

Stack<Clause> getCurrentClauseStack()

getSqmQueryPartStack

Stack<SqmQueryPart> getSqmQueryPartStack()

getCurrentSqmQueryPart

default SqmQueryPart<?> getCurrentSqmQueryPart()

registerQueryTransformer

void registerQueryTransformer(QueryTransformer transformer)

getCurrentlyProcessingJoinType

@Nullable
SqlAstJoinType getCurrentlyProcessingJoinType()

Returns the SqlAstJoinType of the currently processing join if there is one, or null. This is used to determine the join type for implicit joins happening in the ON clause.

isInTypeInference

boolean isInTypeInference()

Returns whether the state of the translation is currently in type inference mode. This is useful to avoid type inference based on other incomplete inference information.

resolveFunctionImpliedReturnType

MappingModelExpressible<?> resolveFunctionImpliedReturnType()

Returns the function return type implied from the context within which it is used. If there is no current function being processed or no context implied type, the return is null.

determineValueMapping

MappingModelExpressible<?> determineValueMapping(SqmExpression<?> sqmExpression)

visitWithInferredType

Object visitWithInferredType(SqmVisitableNode node,
                             Supplier<MappingModelExpressible<?>> inferredTypeAccess)

Visits the given node with the given inferred type access.

expandSelfRenderingFunctionMultiValueParameter

List<Expression> expandSelfRenderingFunctionMultiValueParameter(SqmParameter<?> sqmParameter)

visitNestedTopLevelPredicate

Predicate visitNestedTopLevelPredicate(SqmPredicate predicate)

resolveMetadata

default <S,M> M resolveMetadata(S source,
                                      Function<S,M> producer)

Resolve a generic metadata object from the provided source, using the specified producer.
