类 CustomBooleanEditor

java.lang.Object

java.beans.PropertyEditorSupport

org.springframework.beans.propertyeditors.CustomBooleanEditor

所有已实现的接口:

PropertyEditor

public class CustomBooleanEditor
extends PropertyEditorSupport

Property editor for Boolean/boolean properties.

This is not meant to be used as system PropertyEditor but rather as locale-specific Boolean editor within custom controller code, to parse UI-caused boolean strings into boolean properties of beans and check them in the UI form.

In web MVC code, this editor will typically be registered with binder.registerCustomEditor calls.

CustomBooleanEditor

public CustomBooleanEditor(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

CustomBooleanEditor

public CustomBooleanEditor(@Nullable
                           String trueString,
                           @Nullable
                           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
