UISelectBoolean 是表示单个 boolean 值（true 或 false）的 UIComponent。它最常呈现为一个复选框。

默认情况下，rendererType 属性必须设置为 "javax.faces.Checkbox"。可以调用 setRendererType() 方法更改此值。

英文文档：

UISelectBoolean is a UIComponent that represents a single boolean (true or false) value. It is most commonly rendered as a checkbox.

By default, the rendererType property must be set to "javax.faces.Checkbox". This value can be changed by calling the setRendererType() method.

Field Detail

英文文档：

COMPONENT_TYPE 

public static final String COMPONENT_TYPE

The standard component type for this component.

See Also:
Constant Field Values

英文文档：

COMPONENT_FAMILY 

public static final String COMPONENT_FAMILY

The standard component family for this component.

See Also:
Constant Field Values

Constructor Detail

public UISelectBoolean()

使用默认属性值创建新的 UISelectBoolean 实例。

英文文档：

UISelectBoolean

public UISelectBoolean()

Create a new UISelectBoolean instance with default property values.

Method Detail

public String getFamily()
英文文档：

getFamily

public String getFamily()
Description copied from class: UIComponent

Return the identifier of the component family to which this component belongs. This identifier, in conjunction with the value of the rendererType property, may be used to select the appropriate Renderer for this component instance.

Overrides:
getFamily in class UIInput

public boolean isSelected()

返回此组件选定状态的本地值。此方法是 getValue() 的一个类型安全别名。

英文文档：

isSelected

public boolean isSelected()

Return the local value of the selected state of this component. This method is a typesafe alias for getValue().

public void setSelected(boolean selected)

设置此组件选定状态的本地值。此方法是 setValue() 的一个类型安全别名。

selected 新的选定状态
英文文档：

setSelected

public void setSelected(boolean selected)

Set the local value of the selected state of this component. This method is a typesafe alias for setValue().

Parameters:
selected - The new selected state

public ValueBinding getValueBinding(String name)

如果请求 selected 的 ValueBinding，则返回任何为 value 设置的 ValueBinding；否则，执行此方法的默认超类处理。

依赖于超类实现来包装 ValueBinding 中返回的 ValueExpression。

name 要为其获取 ValueBinding 的属性的名称
ThrowsNullPointerException: 如果 name 为 null
deprecated 此方法已由 #getValueExpression 替代。
英文文档：

getValueBinding

public ValueBinding getValueBinding(String name)
Deprecated. This has been replaced by getValueExpression(java.lang.String).

Return any ValueBinding set for value if a ValueBinding for selected is requested; otherwise, perform the default superclass processing for this method.

Rely on the superclass implementation to wrap the returned ValueExpression in a ValueBinding.

Overrides:
getValueBinding in class UIComponentBase
Parameters:
name - Name of the attribute or property for which to retrieve a ValueBinding
Throws:
NullPointerException - if name is null

public void setValueBinding(String name, ValueBinding binding)

存储 value 下为 selected 指定的任何 ValueBinding；否则，执行此方法的默认超类处理。

依赖于超类实现来包装 ValueExpression 中的参数 ValueBinding。

name 要为其设置 ValueBinding 的属性的名称
binding 要设置的 ValueBinding，或为 null 以移除任何当前设置的 ValueBinding
ThrowsNullPointerException: 如果 name 为 null
deprecated 此方法已由 #setValueExpression 替代。
英文文档：

setValueBinding

public void setValueBinding(String name,
                            ValueBinding binding)
Deprecated. This has been replaced by setValueExpression(java.lang.String, javax.el.ValueExpression).

Store any ValueBinding specified for selected under value instead; otherwise, perform the default superclass processing for this method.

Rely on the superclass implementation to wrap the argument ValueBinding in a ValueExpression.

Overrides:
setValueBinding in class UIComponentBase
Parameters:
name - Name of the attribute or property for which to set a ValueBinding
binding - The ValueBinding to set, or null to remove any currently set ValueBinding
Throws:
NullPointerException - if name is null

public ValueExpression getValueExpression(String name)

如果请求 selected 的 ValueExpression，则返回任何为 value 设置的 ValueExpression；否则，执行此方法的默认超类处理。

name 要为其获取 ValueExpression 的属性的名称
ThrowsNullPointerException: 如果 name 为 null
since1.2
英文文档：

getValueExpression

public ValueExpression getValueExpression(String name)

Return any ValueExpression set for value if a ValueExpression for selected is requested; otherwise, perform the default superclass processing for this method.

Overrides:
getValueExpression in class UIComponent
Parameters:
name - Name of the attribute or property for which to retrieve a ValueExpression
Throws:
NullPointerException - if name is null
Since:
1.2

public void setValueExpression(String name, ValueExpression binding)

存储 value 下为 selected 指定的任何 ValueExpression；否则，执行此方法的默认超类处理。

name 要为其设置 ValueExpression 的属性的名称
binding 要设置的 ValueExpression，或为 null 以移除任何当前设置的 ValueExpression
ThrowsNullPointerException: 如果 name 为 null
since1.2
英文文档：

setValueExpression

public void setValueExpression(String name,
                               ValueExpression binding)

Store any ValueExpression specified for selected under value instead; otherwise, perform the default superclass processing for this method.

Overrides:
setValueExpression in class UIComponent
Parameters:
name - Name of the attribute or property for which to set a ValueExpression
