    public class ArgumentConvertingMethodInvoker

extends MethodInvoker

Subclass of MethodInvoker that tries to convert the given arguments for the actual target method via BeanWrapperImpl.

Supports flexible argument conversions, in particular for invoking a specific overloaded method.

Constructor Detail

### ArgumentConvertingMethodInvoker

    public ArgumentConvertingMethodInvoker()

Method Detail

### setTypeConverter

    public void setTypeConverter(TypeConverter typeConverter)

  Set a TypeConverter to use for argument type conversion.

  Default is a `SimpleTypeConverter`. Can be overridden with any TypeConverter implementation, typically a pre-configured SimpleTypeConverter or a BeanWrapperImpl instance.

  See Also:
    `SimpleTypeConverter`, `BeanWrapperImpl`

### getTypeConverter

    public TypeConverter getTypeConverter()

  Return the TypeConverter used for argument type conversion.

  Can be cast to `PropertyEditorRegistry` if direct access to the underlying PropertyEditors is desired (provided that the present TypeConverter actually implements the PropertyEditorRegistry interface).

### getDefaultTypeConverter

    protected TypeConverter getDefaultTypeConverter()

  Obtain the default TypeConverter for this method invoker.

  Called if no explicit TypeConverter has been specified. The default implementation builds a `SimpleTypeConverter`. Can be overridden in subclasses.

### registerCustomEditor

    public void registerCustomEditor(Class requiredType,
                                     PropertyEditor propertyEditor)

  Register the given custom property editor for all properties of the given type.

  Typically used in conjunction with the default `SimpleTypeConverter`; will work with any TypeConverter that implements the PropertyEditorRegistry interface as well.

  Parameters:
    `requiredType` - type of the property
    `propertyEditor` - editor to register
  See Also:
    `setTypeConverter(org.springframework.beans.TypeConverter)`, `PropertyEditorRegistry.registerCustomEditor(java.lang.Class, java.beans.PropertyEditor)`

### findMatchingMethod

    protected Method findMatchingMethod()

  This implementation looks for a method with matching parameter types: that is, where each argument value is assignable to the corresponding parameter type.

  Overrides:
    `findMatchingMethod` in class `MethodInvoker`
  Returns:
    a matching method, or `null` if none
  See Also:
    `MethodInvoker.getTargetClass()`, `MethodInvoker.getTargetMethod()`, `MethodInvoker.getArguments()`
