Interface Summary

Interface	Description
ParameterAccessor	Interface to access method parameters.
QueryByExampleExecutor<T>	Interface to allow execution of Query by Example Example instances.
QueryLookupStrategy	Strategy interface for which way to lookup RepositoryQuerys.
QueryMethodEvaluationContextProvider	Provides a way to access a centrally defined potentially shared EvaluationContext.
ReactiveQueryByExampleExecutor<T>	Interface to allow execution of Query by Example Example instances using a reactive infrastructure.
ReactiveQueryMethodEvaluationContextProvider	Provides a way to access a centrally defined potentially shared EvaluationContext by considering ReactiveEvaluationContextExtension.
RepositoryQuery	Interface for a query abstraction.

Class Summary

Class	Description
DefaultParameters	Default implementation of Parameters.
ExtensionAwareQueryMethodEvaluationContextProvider	An QueryMethodEvaluationContextProvider that assembles an EvaluationContext from a list of EvaluationContextExtension instances.
Parameter	Class to abstract a single parameter of a query method.
Parameters<S extends Parameters<S,T>,T extends Parameter>	Abstracts method parameters that have to be bound to query parameters or applied to the query independently.
ParametersParameterAccessor	ParameterAccessor implementation using a Parameters instance to find special parameters.
QueryMethod	Abstraction of a method that is designated to execute a finder query.
ReactiveExtensionAwareQueryMethodEvaluationContextProvider	An reactive QueryMethodEvaluationContextProvider that assembles an EvaluationContext from a list of EvaluationContextExtension and ReactiveEvaluationContextExtension.
ResultProcessor	A ResultProcessor to expose metadata about query result element projection and eventually post processing raw query results into projections and data transfer objects.
ReturnedType	A representation of the type returned by a QueryMethod.
SpelEvaluator	Evaluates SpEL expressions as extracted by the SpelQueryContext.SpelExtractor based on parameter information from a method and parameter values from a method call.
SpelQueryContext	Source of SpelQueryContext.SpelExtractor encapsulating configuration often common for all queries.
SpelQueryContext.EvaluatingSpelQueryContext	An extension of SpelQueryContext that can create SpelEvaluator instances as it also knows about a QueryMethodEvaluationContextProvider.

Enum Summary

Enum	Description

Exception Summary

Exception	Description
ParameterOutOfBoundsException	Exception to be thrown when trying to access a Parameter with an invalid index inside a Parameters instance.
QueryCreationException	Exception to be thrown if a query cannot be created from a QueryMethod.

Annotation Types Summary

Annotation Type	Description
Param	Annotation to bind method parameters to a query via a named parameter.
