javax.accessibility.AccessibleValue
The AccessibleValue interface should be supported by any object that supports a numerical value (e.g., a scroll bar). This interface provides the standard mechanism for an assistive technology to determine and set the numerical value as well as get the minimum and maximum values. Applications can determine if an object supports the AccessibleValue interface by first obtaining its AccessibleContext (see Accessible) and then calling the AccessibleContext.getAccessibleValue() method. If the return value is not null, the object supports this interface.

get-current-accessible-valueclj
(get-current-accessible-value this)Get the value of this object as a Number. If the value has not been set, the return value will be null.
returns: value of the object - java.lang.Number
Get the value of this object as a Number. If the value has not been set, the return value will be null. returns: value of the object - `java.lang.Number`
get-maximum-accessible-valueclj
(get-maximum-accessible-value this)Get the maximum value of this object as a Number.
returns: Maximum value of the object; null if this object does not
have a maximum value - java.lang.Number
Get the maximum value of this object as a Number. returns: Maximum value of the object; null if this object does not have a maximum value - `java.lang.Number`
get-minimum-accessible-valueclj
(get-minimum-accessible-value this)Get the minimum value of this object as a Number.
returns: Minimum value of the object; null if this object does not
have a minimum value - java.lang.Number
Get the minimum value of this object as a Number. returns: Minimum value of the object; null if this object does not have a minimum value - `java.lang.Number`
set-current-accessible-valueclj
(set-current-accessible-value this n)Set the value of this object as a Number.
n - the number to use for the value - java.lang.Number
returns: True if the value was set; else False - boolean
Set the value of this object as a Number. n - the number to use for the value - `java.lang.Number` returns: True if the value was set; else False - `boolean`
