Examples of org.springframework.beans.TypeConverter.convertIfNecessary()

org.springframework.beans.TypeConverter.convertIfNecessary()
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. @param value the value to convert @param requiredType the type we must convert to(or null if not known, for example in case of a collection element) @return the new value, possibly the result of type conversion @throws TypeMismatchException if type conversion failed @see java.beans.PropertyEditor#setAsText(String) @see java.beans.PropertyEditor#getValue()
