Class Summary

Class	Description
AbstractSqmExpression<T>
AbstractSqmParameter<T>	Common support for SqmParameter impls
Compatibility
Conversion	A conversion of a duration to a given temporal unit, as a result of applying the 'by unit' operator.
JpaCriteriaParameter<T>	JpaParameterExpression created via JPA CriteriaBuilder.
NullSqmExpressible
SqmAliasedNodeRef	Models a reference to a SqmAliasedNode used in the order-by or group-by clause by either position or alias, though the reference is normalized here to a positional ref
SqmAny<T>
SqmAnyDiscriminatorValue<T>
SqmBinaryArithmetic<T>
SqmByUnit
SqmCaseSearched<R>
SqmCaseSearched.WhenFragment<R>
SqmCaseSimple<T,R>
SqmCaseSimple.WhenFragment<T,R>

SqmCollation
SqmCollectionSize	Represents the SIZE() function.
SqmDistinct<T>

SqmEnumLiteral<E extends Enum<E>>	Specialized SQM literal defined by an enum reference.
SqmEvery<T>
SqmExpressionHelper
SqmExtractUnit<T>
SqmFieldLiteral<T>
SqmFormat	Effectively a query-literal but we want to handle it specially in the SQM to SQL AST conversion
SqmFunction<T>	A SQM function
SqmHqlNumericLiteral<N extends Number>	Used to model numeric literals found in HQL queries.
SqmJpaCriteriaParameterWrapper<T>	Acts as the per-use wrapper for a JpaCriteriaParameter (CriteriaBuilder.parameter(java.lang.Class<T>)).
SqmLiteral<T>	Represents a literal value in the sqm, e.g. 1 'some string' some.JavaClass.CONSTANT some.JavaEnum.VALUE etc
SqmLiteralEntityType<T>	Represents an reference to an entity type as a literal.
SqmLiteralNull<T>
SqmModifiedSubQueryExpression<T>	Represents a SqmModifiedSubQueryExpression.Modifier.ALL, SqmModifiedSubQueryExpression.Modifier.ANY, SqmModifiedSubQueryExpression.Modifier.SOME modifier applied to a subquery as part of a comparison.
SqmNamedParameter<T>	Represents a named query parameter in the SQM tree.
SqmOver<T>
SqmOverflow<T>
SqmParameterizedEntityType<T>	Entity type expression based on a parameter - `TYPE( :someParam )`
SqmPositionalParameter<T>	Models a positional parameter expression
SqmSelfRenderingExpression<T>
SqmStar
SqmSummarization<T>
SqmToDuration<T>
SqmTrimSpecification	Needed to pass TrimSpecification as an SqmExpression when we call out to SqmFunctionTemplates handling TRIM calls as a function argument.
SqmTuple<T>	A tuple constructor, that is, a list of expressions wrapped in parentheses, for example, (x, y, z).
SqmUnaryOperation<T>
SqmWindow
SqmWindowFrame
ValueBindJpaCriteriaParameter<T>	It is a JpaCriteriaParameter created from a value when ValueHandlingMode is equal to BIND
