类 PropertyEditorRegistrySupport

构造器详细资料

• PropertyEditorRegistrySupport

  public PropertyEditorRegistrySupport()

方法详细资料

• setConversionService

  public void setConversionService​(ConversionService conversionService)

  Specify a Spring 3.0 ConversionService to use for converting property values, as an alternative to JavaBeans PropertyEditors.

• getConversionService

  public ConversionService getConversionService()

  Return the associated ConversionService, if any.

• registerDefaultEditors

  protected void registerDefaultEditors()

  Activate the default editors for this registry instance, allowing for lazily registering default editors when needed.

• useConfigValueEditors

  public void useConfigValueEditors()

  Activate config value editors which are only intended for configuration purposes, such as StringArrayPropertyEditor.

  Those editors are not registered by default simply because they are in general inappropriate for data binding purposes. Of course, you may register them individually in any case, through registerCustomEditor(java.lang.Class<?>, java.beans.PropertyEditor).

• overrideDefaultEditor

  public void overrideDefaultEditor​(Class<?> requiredType,
                                    PropertyEditor propertyEditor)

  Override the default editor for the specified type with the given property editor.

  Note that this is different from registering a custom editor in that the editor semantically still is a default editor. A ConversionService will override such a default editor, whereas custom editors usually override the ConversionService.

  参数:

  requiredType - the type of the property

  propertyEditor - the editor to register

  另请参阅:

  registerCustomEditor(Class, PropertyEditor)

• getDefaultEditor

  public PropertyEditor getDefaultEditor​(Class<?> requiredType)

  Retrieve the default editor for the given property type, if any.

  Lazily registers the default editors, if they are active.

  参数:

  requiredType - type of the property

  返回:

  the default editor, or null if none found

  另请参阅:

  registerDefaultEditors()

• copyDefaultEditorsTo

  protected void copyDefaultEditorsTo​(PropertyEditorRegistrySupport target)

  Copy the default editors registered in this instance to the given target registry.

  参数:

  target - the target registry to copy to

• registerCustomEditor

  public void registerCustomEditor​(Class<?> requiredType,
                                   PropertyEditor propertyEditor)

  从接口复制的说明: PropertyEditorRegistry
  Register the given custom property editor for all properties of the given type.

  指定者:

  registerCustomEditor 在接口中 PropertyEditorRegistry

  参数:

  requiredType - the type of the property

  propertyEditor - the editor to register

• registerCustomEditor

  public void registerCustomEditor​(Class<?> requiredType,
                                   String propertyPath,
                                   PropertyEditor propertyEditor)

  从接口复制的说明: PropertyEditorRegistry
  Register the given custom property editor for the given type and property, or for all properties of the given type.

  If the property path denotes an array or Collection property, the editor will get applied either to the array/Collection itself (the PropertyEditor has to create an array or Collection value) or to each element (the PropertyEditor has to create the element type), depending on the specified required type.

  Note: Only one single registered custom editor per property path is supported. In the case of a Collection/array, do not register an editor for both the Collection/array and each element on the same property.

  For example, if you wanted to register an editor for "items[n].quantity" (for all values n), you would use "items.quantity" as the value of the 'propertyPath' argument to this method.

  指定者:

  registerCustomEditor 在接口中 PropertyEditorRegistry

  参数:

  requiredType - the type of the property. This may be null if a property is given but should be specified in any case, in particular in case of a Collection - making clear whether the editor is supposed to apply to the entire Collection itself or to each of its entries. So as a general rule: Do not specify null here in case of a Collection/array!

  propertyPath - the path of the property (name or nested path), or null if registering an editor for all properties of the given type

  propertyEditor - editor to register

• findCustomEditor

  public PropertyEditor findCustomEditor​(Class<?> requiredType,
                                         String propertyPath)

  从接口复制的说明: PropertyEditorRegistry
  Find a custom property editor for the given type and property.

  指定者:

  findCustomEditor 在接口中 PropertyEditorRegistry

  参数:

  requiredType - the type of the property (can be null if a property is given but should be specified in any case for consistency checking)

  propertyPath - the path of the property (name or nested path), or null if looking for an editor for all properties of the given type

  返回:

  the registered editor, or null if none

• hasCustomEditorForElement

  public boolean hasCustomEditorForElement​(Class<?> elementType,
                                           String propertyPath)

  Determine whether this registry contains a custom editor for the specified array/collection element.

  参数:

  elementType - the target type of the element (can be null if not known)

  propertyPath - the property path (typically of the array/collection; can be null if not known)

  返回:

  whether a matching custom editor has been found

• getPropertyType

  protected Class<?> getPropertyType​(String propertyPath)

  Determine the property type for the given property path.

  Called by findCustomEditor(java.lang.Class<?>, java.lang.String) if no required type has been specified, to be able to find a type-specific editor even if just given a property path.

  The default implementation always returns null. BeanWrapperImpl overrides this with the standard getPropertyType method as defined by the BeanWrapper interface.

  参数:

  propertyPath - the property path to determine the type for

  返回:

  the type of the property, or null if not determinable

  另请参阅:

  PropertyAccessor.getPropertyType(String)

• guessPropertyTypeFromEditors

  protected Class<?> guessPropertyTypeFromEditors​(String propertyName)

  Guess the property type of the specified property from the registered custom editors (provided that they were registered for a specific type).

  参数:

  propertyName - the name of the property

  返回:

  the property type, or null if not determinable

• copyCustomEditorsTo

  protected void copyCustomEditorsTo​(PropertyEditorRegistry target,
                                     String nestedProperty)

  Copy the custom editors registered in this instance to the given target registry.

  参数:

  target - the target registry to copy to

  nestedProperty - the nested property path of the target registry, if any. If this is non-null, only editors registered for a path below this nested property will be copied. If this is null, all editors will be copied.
