Class Value

  • All Implemented Interfaces:
    java.lang.Cloneable

    public class Value
    extends java.lang.Object
    implements java.lang.Cloneable
    This is the base class for all data values that are stored in VirtualSpace.

    Note:

    Please note that conversion of a Value and a VSField is done in different manners. The VSField can use its Field Actors to perform a conversion that is more accurate than the conversion using the Value methods toNnnn(), e.g. to convert an Integer into a String that could be "green", "red" or "blue", and vice-versa.

    The Value class also provides additional conversion routines to Java Date, SQL Date/Time/Timestamp and GregorianCalendar.

    This class is immutable and thread-safe.

    The data value types are closely related the JDBC and XML data types as follows:
