Class Conversions.Converter

  • Enclosing class:
    Conversions
    public abstract static class Conversions.Converter
extends java.lang.Object
    A converter converts a value to its representation as a specific target type. Not all target types might be supported for a given value in which case implementations throw an exception. The default implementations of the various conversion methods all operate on the string representation of the underlying value (i.e. call Converter.toString().
