Class DateTransform<T extends java.util.Date>

  • All Implemented Interfaces:
    Transform<T>

    class DateTransform<T extends java.util.Date>
    extends java.lang.Object
    implements Transform<T>
    The DateTransform object is used to transform date values to and from string representations, which will be inserted in the generated XML document as the value place holder. The value must be readable and writable in the same format. Fields and methods annotated with the XML attribute annotation will use this to persist and retrieve the value to and from the XML source.
     
        @Attribute
        private Date date;
        
     
    As well as the XML attribute values using transforms, fields and methods annotated with the XML element annotation will use this. Aside from the obvious difference, the element annotation has an advantage over the attribute annotation in that it can maintain any references using the CycleStrategy object.

      • DateTransform

        public DateTransform​(java.lang.Class<T> type)
                      throws java.lang.Exception
        Constructor for the DateTransform object. This is used to create a transform using a specified date format. The format should typically contain enough information to create the date using a different locale or time zone between read and write operations.
        Parameters:
        type - this is the type of date to be created by this
        Throws:
        java.lang.Exception

      • read

        public T read​(java.lang.String text)
               throws java.lang.Exception
        This method is used to convert the string value given to an appropriate representation. This is used when an object is being deserialized from the XML document and the value for the string representation is required.
        Specified by:
        read in interface Transform<T extends java.util.Date>
        Parameters:
        text - the string representation of the date value
        Returns:
        this returns an appropriate instanced to be used
        Throws:
        java.lang.Exception
      • write

        public java.lang.String write​(T date)
                               throws java.lang.Exception
        This method is used to convert the provided value into an XML usable format. This is used in the serialization process when there is a need to convert a field value in to a string so that that value can be written as a valid XML entity.
        Specified by:
        write in interface Transform<T extends java.util.Date>
        Parameters:
        date - this is the value to be converted to a string
        Returns:
        this is the string representation of the given date
        Throws:
        java.lang.Exception
