- org.springframework.web.servlet.mvc.method.annotation.MatrixVariableMapMethodArgumentResolver

All Implemented Interfaces:
HandlerMethodArgumentResolver
```
public class MatrixVariableMapMethodArgumentResolver
extends Object
implements HandlerMethodArgumentResolver
```
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.

    supportsParameter in interface HandlerMethodArgumentResolver
    Parameters:
    parameter - the method parameter to check

```
    Description copied from interface: HandlerMethodArgumentResolver
    Resolves a method parameter into an argument value from a given request. A ModelAndViewContainer provides access to the model for the request. A WebDataBinderFactory provides a way to create a WebDataBinder instance when needed for data binding and type conversion purposes.
    Specified by:
    resolveArgument in interface HandlerMethodArgumentResolver
    Parameters:
    parameter - the method parameter to resolve. This parameter must have previously been passed to HandlerMethodArgumentResolver.supportsParameter(org.springframework.core.MethodParameter) which must have returned true.
    mavContainer - the ModelAndViewContainer for the current request
    request - the current request
    binderFactory - a factory for creating WebDataBinder instances
    Returns:
    the resolved argument value, or null if not resolvable
    Throws:
    Exception - in case of errors with the preparation of argument values
