org.springframework.beans.propertyeditors

## 类 CharacterEditor

- java.lang.Object
- - java.beans.PropertyEditorSupport
  - - org.springframework.beans.propertyeditors.CharacterEditor

- 所有已实现的接口:
    PropertyEditor

      public class CharacterEditor
      extends PropertyEditorSupport

  Editor for a `Character`, to populate a property of type `Character` or `char` from a String value.

  Note that the JDK does not contain a default `property editor` for `char`! `BeanWrapperImpl` will register this editor by default.

  Also supports conversion from a Unicode character sequence; e.g. `u0041` ('A').

  从以下版本开始:
    1.2

    - #### CharacterEditor

          public CharacterEditor(boolean allowEmpty)

      Create a new CharacterEditor instance.

      The "allowEmpty" parameter controls whether an empty String is to be allowed in parsing, i.e. be interpreted as the `null` value when `text is being converted`. If `false`, an `IllegalArgumentException` will be thrown at that time.

      参数:
        `allowEmpty` - if empty strings are to be allowed

  - ### 方法详细资料

    - #### setAsText

          public void setAsText(@Nullable
                                String text)
                         throws IllegalArgumentException

      指定者:
        `setAsText` 在接口中 `PropertyEditor`
      覆盖:
        `setAsText` 在类中 `PropertyEditorSupport`
      抛出:
        `IllegalArgumentException`

    - #### getAsText

          public String getAsText()

      指定者:
        `getAsText` 在接口中 `PropertyEditor`
      覆盖:
        `getAsText` 在类中 `PropertyEditorSupport`
