Public Methods
public abstract T convertIfNecessary (Object value, Class<T> requiredType)
Convert the value to the required type (if necessary from a String).
Conversions from String to any type will typically use the setAsText
method of the PropertyEditor class. Note that a PropertyEditor must be registered
for the given class for this to work; this is a standard JavaBeans API.
A number of PropertyEditors are automatically registered.
Parameters
| value | the value to convert |
|---|---|
| requiredType | the type we must convert to
(or null if not known, for example in case of a collection element) |
Returns
- the new value, possibly the result of type conversion
Throws
| TypeMismatchException | if type conversion failed |
|---|
