Interface Summary

Interface	Description
ConstructionInterceptor	An AOP-style hook to intercept individual steps of predicate construction.
Ordering	Defines one criterion of a sorting clause.
PredicateTransformation	An interface for predicate transformations.
Query	Base interface of all queries.
QueryHint	Marker interface for query hints.
QueryParameter	An operand of a Predicate or Ordering.
QueryParameterMapper	Interface to map from a given source query parameter to a target query parameter.

Class Summary

Class	Description
AggregateReferenceValue	Reference value which aggregates based on a specific strategy.
BaseQuery	Base class for all queries.
BaseQuery.BaseQueryBuilder<Q extends BaseQuery,SELF extends BaseQuery.BaseQueryBuilder<Q,SELF>>
BaseQuery.QueryData	Data container that holds the state of a query object.
BasicOperand<T>	Wraps a QueryParameter (i.e. left operand) and allows to build Predicates.
BasicOperand.InnerSelectReferenceValue	Inner select reference value used by the BasicOperand.eq(Predicate) method to render the inner select statement with the given parameter as the column name and the given predicate as the right operand.
BooleanOperand	An operand implementation which builds Predicate instances through boolean-specific operators.
ComparisonPredicate	A predicate which compares a query parameter (i.e. left operand) with an expected value (i.e. right operand) based on a specific operator.
CompositePredicate	A logical concatenation of n predicates, which itself is again a predicate.
DateOperand	An operand implementation which builds Predicate instances through date-specific operators.
InnerSelectInPredicate	A predicate which compares a query parameter (i.e. left operand) with an inner select predicate (i.e. right operand) based on a IN operator.
InPredicate	A predicate which compares a query parameter (i.e. left operand) with a set of possible values (i.e. right operand) based on a IN operator.
MergeCompositesPredicateTransformation	Merges predicates with minimized levels of nesting (resulting in SQL with a minimal number of parentheses).
NeverMatchingPredicate	A tagging predicate which never matches.
NotNullPredicate	A predicate whose right operand is always not null.
NotPredicate	Negating wrapper around an arbitrary predicate.
NullPredicate	A predicate whose right operand always equals null.
NumberOperand<T extends Number>	An operand implementation which builds Predicate instances through number-specific operators.
Predicate	Defines a criterion to be matched in a Query.
Predicates	This class implements basic operations with predicates
PredicateUtils	Utility class to deal with predicates.
QueryParameterPredicate	Predicates that have a QueryParameter as their left operand.
RawPredicate	A predicate expressed through a raw sql where-clause.
RenderingModePredicate	Predicate which can enforce rendering mode
SimpleOrdering	Default implementations of the Ordering interface.
StringOperand	An operand implementation which builds Predicate instances through string-specific operators.

Enum Summary

Enum	Description
AggregateReferenceValue.AggregationStrategy
ComparisonOperator	Used to combine two operands to a Predicate.
CompositePredicate.Operator	The logical operator which defines the type of concatenation.
Ordering.Direction	The sorting direction.
