Class DefaultFormatterFactory

java.lang.Object
org.eclipse.nebula.widgets.formattedtext.DefaultFormatterFactory
public abstract class DefaultFormatterFactory
extends java.lang.Object
Factory for the default formatters.

This factory is called by FormattedText when a value is setted and no formatter has been provided by constructor or setFormatter(). The default formatter is based on the class of the value. The cache is searched first for the exact value's class. If no formatter is found, then it is searched for any class that is an ancestor of the value's class. The cache is a HashMap and the order of search cannot be garanteed. The first valid ancestor found is returned.

Default formatters provided by the factory are:

  • DateFormatter for Date values
  • NumberFormatter for Number values
Other formatters can be added with the register() method. Each formatter class must implement ITextFormatter and must have a default constructor.

This class is not intended to be instanciated.
