    • toDataType

      public DataType toDataType() throws DuplicateNameException, 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
      IOException
