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:

构造器详细资料

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
