MatrixVariableMapMethodArgumentResolver (Spring Framework 5.2.12.RELEASE API)

java.lang.Object
- org.springframework.web.reactive.result.method.HandlerMethodArgumentResolverSupport
- - org.springframework.web.reactive.result.method.annotation.MatrixVariableMapMethodArgumentResolver

All Implemented Interfaces:
HandlerMethodArgumentResolver, SyncHandlerMethodArgumentResolver
```
public class MatrixVariableMapMethodArgumentResolver
extends HandlerMethodArgumentResolverSupport
implements SyncHandlerMethodArgumentResolver
```
Resolves arguments of type Map annotated with @MatrixVariable where the annotation does not specify a name. In other words the purpose of this resolver is to provide access to multiple matrix variables, either all or associated with a specific path variable.
When a name is specified, an argument of type Map is considered to be a single attribute with a Map value, and is resolved by MatrixVariableMethodArgumentResolver instead.
