public abstract class NumericField
Backwards compatible version of the 1.0.7 NumericField component.
Parameter | Type | Read / Write | Required | Default | Description |
value | Number |
R / W | yes | The value to be updated.
When the form is submitted, this parameter is only updated if the value is valid. When rendering, a null value will render as the empty string. A value of zero will render normally. When the form is submitted, the type of the binding is used to determine what kind of object to convert the string to. |
|
minimum | Number |
R | no | The minimum value accepted for the field. | |
maximum | Number |
R | no | The maximum value accepted for the field. | |
required | boolean | R | no | false | If true, then a non-null value must be provided. If the field is not required, and a null (all whitespace) value is supplied in the field, then the value parameter is not updated. |
displayName | String | R | yes | A textual name for the field that is used when formulating error messages. | |
type | String | R | yes | The class name used to convert the value entered. See
NumberValidator.setValueType(String) |
May not contain a body. May have informal parameters.
