所有已实现的接口:

java.beans.PropertyEditor

public class BooleanBinder
extends java.beans.PropertyEditorSupport

绑定的策略：当request中有与bean中相同的PropertyName时，就把request的Parameter值注入，当该值为null时，则跳过，保留bean的原有值

BooleanBinder

public BooleanBinder(boolean allowEmpty)

Create a new CustomBooleanEditor instance, with "true"/"on"/"yes" and "false"/"off"/"no" as recognized String values.

The "allowEmpty" parameter states if an empty String should be allowed for parsing, i.e. get interpreted as null value. Else, an IllegalArgumentException gets thrown in that case.

参数:

allowEmpty - if empty strings should be allowed

BooleanBinder

public BooleanBinder(java.lang.String trueString,
                     java.lang.String falseString,
                     boolean allowEmpty)

Create a new CustomBooleanEditor instance, with configurable String values for true and false.

The "allowEmpty" parameter states if an empty String should be allowed for parsing, i.e. get interpreted as null value. Else, an IllegalArgumentException gets thrown in that case.

参数:

trueString - the String value that represents true: for example, "true" (VALUE_TRUE), "on" (VALUE_ON), "yes" (VALUE_YES) or some custom value

falseString - the String value that represents false: for example, "false" (VALUE_FALSE), "off" (VALUE_OFF), "no" (VALUE_NO) or some custom value

allowEmpty - if empty strings should be allowed
