Method Summary

All Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`protected AbstractNamedValueArgumentResolver.NamedValueInfo`	`createNamedValueInfo(MethodParameter parameter)`	Create the `AbstractNamedValueArgumentResolver.NamedValueInfo` object for the given method parameter.
`protected void`	`handleMissingValue(String name, MethodParameter parameter)`	Invoked when a named value is required, but `AbstractNamedValueArgumentResolver.resolveName(String, MethodParameter, ServerWebExchange)` returned `null` and there is no default value.
`protected reactor.core.publisher.Mono<Object>`	`resolveName(String name, MethodParameter parameter, ServerWebExchange exchange)`	Resolve the given parameter type and value name into an argument value.
`boolean`	`supportsParameter(MethodParameter parameter)`	Whether this resolver supports the given method parameter.

public boolean supportsParameter(MethodParameter parameter)
```
    Description copied from interface: HandlerMethodArgumentResolver
    Whether this resolver supports the given method parameter.
    Parameters:
    parameter - the method parameter
  - createNamedValueInfo
```
protected AbstractNamedValueArgumentResolver.NamedValueInfo createNamedValueInfo(MethodParameter parameter)
```
    Description copied from class: AbstractNamedValueArgumentResolver
    Create the AbstractNamedValueArgumentResolver.NamedValueInfo object for the given method parameter. Implementations typically retrieve the method annotation by means of MethodParameter.getParameterAnnotation(Class).
    Specified by:
    createNamedValueInfo in class AbstractNamedValueArgumentResolver
    Parameters:
    parameter - the method parameter
    Returns:
    the named value information
  - resolveName
```
protected reactor.core.publisher.Mono<Object> resolveName(String name,
                                                          MethodParameter parameter,
                                                          ServerWebExchange exchange)
```
    Description copied from class: AbstractNamedValueArgumentResolver
    Resolve the given parameter type and value name into an argument value.
    Specified by:
    resolveName in class AbstractNamedValueArgumentResolver
    Parameters:
    name - the name of the value being resolved
    parameter - the method parameter to resolve to an argument value (pre-nested in case of a Optional declaration)
    exchange - the current exchange
    Returns:
    the resolved argument (may be empty Mono)
  - handleMissingValue
```
protected void handleMissingValue(String name,
                                  MethodParameter parameter)
```
    Description copied from class: AbstractNamedValueArgumentResolver
    Invoked when a named value is required, but AbstractNamedValueArgumentResolver.resolveName(String, MethodParameter, ServerWebExchange) returned null and there is no default value. Subclasses typically throw an exception in this case.
    Overrides:
    handleMissingValue in class AbstractNamedValueArgumentResolver
    Parameters:
    name - the name for the value
    parameter - the method parameter
