Class ReflectionBeanIntrospector

java.lang.Object

io.micronaut.reflection.ReflectionBeanIntrospector

All Implemented Interfaces:

BeanIntrospector

public final class ReflectionBeanIntrospector
extends Object
implements BeanIntrospector

A BeanIntrospector that serves the generated introspections of another introspector first, and a ReflectionBeanIntrospection for a type that has none.

The reflective introspections cannot be enumerated, so findIntrospections(Predicate) and findIntrospectedTypes(Predicate) return what the delegate returns.

This introspector is for the code paths a specification requires to handle any class; it is not a replacement of BeanIntrospector.SHARED, whose callers expect a missing introspection to mean that a type was not meant to be introspected.

Since:

5.2.0

Constructor	Description
ReflectionBeanIntrospector(BeanIntrospector delegate)	Creates an introspector reflecting over every type the delegate does not know.
ReflectionBeanIntrospector(BeanIntrospector delegate, Predicate<Class<?>> reflective)	Creates an introspector reflecting over the types the delegate does not know among the ones a predicate accepts.
ReflectionBeanIntrospector(BeanIntrospector delegate, Predicate<Class<?>> reflective, boolean supplementing)	Creates an introspector reflecting over the types the delegate does not know among the ones a predicate accepts, completing the generated introspections when asked to.
ReflectionBeanIntrospector(BeanIntrospector delegate, Predicate<Class<?>> reflective, boolean supplementing, Set<Introspected.AccessKind> accessKinds)	Creates an introspector describing the types the delegate does not know with the members a caller asks for.

Constructor Details

ReflectionBeanIntrospector

public ReflectionBeanIntrospector(BeanIntrospector delegate)

Creates an introspector reflecting over every type the delegate does not know.

Parameters:

delegate - The introspector consulted first

ReflectionBeanIntrospector

public ReflectionBeanIntrospector(BeanIntrospector delegate,
 Predicate<Class<?>> reflective)

Creates an introspector reflecting over the types the delegate does not know among the ones a predicate accepts.

Parameters:

delegate - The introspector consulted first

reflective - The types a reflective introspection may be created for

ReflectionBeanIntrospector

public ReflectionBeanIntrospector(BeanIntrospector delegate,
 Predicate<Class<?>> reflective,
 boolean supplementing)

Creates an introspector reflecting over the types the delegate does not know among the ones a predicate accepts, completing the generated introspections when asked to.

Parameters:

delegate - The introspector consulted first

reflective - The types a reflective introspection may be created for

supplementing - Whether a generated introspection is completed with the executables the processor left out, as a SupplementedBeanIntrospection

ReflectionBeanIntrospector

public ReflectionBeanIntrospector(BeanIntrospector delegate,
 Predicate<Class<?>> reflective,
 boolean supplementing,
 Set<Introspected.AccessKind> accessKinds)

Creates an introspector describing the types the delegate does not know with the members a caller asks for.

A specification that reads a field directly, as Jakarta Validation does, asks for Introspected.AccessKind.FIELD: a type it describes carries no Introspected of its own to declare that, and the default of Introspected.AccessKind.METHOD alone leaves a field without accessors out of the properties.

Parameters:

delegate - The introspector consulted first

reflective - The types a reflective introspection may be created for

supplementing - Whether a generated introspection is completed with the executables the processor left out, as a SupplementedBeanIntrospection

accessKinds - The kinds of member that make a property, empty for what the type declares
