      • toDataType

        public DataType toDataType()
                    throws DuplicateNameException,
                           java.io.IOException
        Description copied from interface: StructConverter
        Returns a structure datatype representing the contents of the implementor of this interface.

        For example, given: 

         class A {
     int foo;
     double bar;
 }

        The return value should be a structure data type with two data type components; an INT and a DOUBLE. The structure should contain field names and, if possible, field comments.

        Specified by:
        toDataType in interface StructConverter
        Returns:
        returns a structure datatype representing the implementor of this interface
        Throws:
        DuplicateNameException - when a datatype of the same name already exists
        java.io.IOException
