Package com.twelvemonkeys.util.convert

Class DefaultConverter

  • All Implemented Interfaces:
    PropertyConverter
    public final class DefaultConverter
extends java.lang.Object
implements PropertyConverter
    Converts strings to objects and back.

    This converter first tries to create an object, using the class' single string argument constructor (<type>(String)) if found, otherwise, an attempt to call the class' static valueOf(String) method. If both fails, a ConversionException is thrown.
