Method Detail

• setTypeConverter

  public void setTypeConverter​(@Nullable
                               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

  @Nullable
  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.

  Overrides:

  findMatchingMethod in class MethodInvoker

  Returns:

  a matching method, or null if none

  See Also:

  doFindMatchingMethod(java.lang.Object[])

• doFindMatchingMethod

  @Nullable
  protected Method doFindMatchingMethod​(Object[] arguments)

  Actually find a method with matching parameter type, i.e. where each argument value is assignable to the corresponding parameter type.

  Parameters:

  arguments - the argument values to match against method parameters

  Returns:

  a matching method, or null if none
