All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected <A extends Annotation> boolean`	`checkAnnotatedParamNoReactiveWrapper(MethodParameter parameter, Class<A> annotationType, BiPredicate<A,Class<?>> typePredicate)`	Evaluate the `Predicate` on the method parameter type if it has the given annotation, nesting within `Optional` if necessary, but raise an `IllegalStateException` if the same matches the generic type within a reactive type wrapper.
`protected boolean`	`checkParameterType(MethodParameter parameter, Predicate<Class<?>> predicate)`	Evaluate the `Predicate` on the method parameter type or on the generic type within a reactive type wrapper.
`protected boolean`	`checkParameterTypeNoReactiveWrapper(MethodParameter parameter, Predicate<Class<?>> predicate)`	Evaluate the `Predicate` on the method parameter type but raise an `IllegalStateException` if the same matches the generic type within a reactive type wrapper.
`ReactiveAdapterRegistry`	`getAdapterRegistry()`	Return the configured `ReactiveAdapterRegistry`.

Method Detail

getAdapterRegistry
```
public ReactiveAdapterRegistry getAdapterRegistry()
```
Return the configured ReactiveAdapterRegistry.

checkParameterType

protected boolean checkParameterType(MethodParameter parameter,
                                     Predicate<Class<?>> predicate)

Evaluate the Predicate on the method parameter type or on the generic type within a reactive type wrapper.

checkParameterTypeNoReactiveWrapper

protected boolean checkParameterTypeNoReactiveWrapper(MethodParameter parameter,
                                                      Predicate<Class<?>> predicate)

Evaluate the Predicate on the method parameter type but raise an IllegalStateException if the same matches the generic type within a reactive type wrapper.

checkAnnotatedParamNoReactiveWrapper

protected <A extends Annotation> boolean checkAnnotatedParamNoReactiveWrapper(MethodParameter parameter,
                                                                              Class<A> annotationType,
                                                                              BiPredicate<A,Class<?>> typePredicate)

Evaluate the Predicate on the method parameter type if it has the given annotation, nesting within Optional if necessary, but raise an IllegalStateException if the same matches the generic type within a reactive type wrapper.
