All Implemented Interfaces:

java.io.Serializable

public class DLITypeInfoList
extends DLITypeInfo

A DLITypeInfoList object is a specialization of a DLITypeInfo object that defines a set of fields that occur more than once. You construct a DLITypeInfoList object by providing the offset and entire length of the fields that repeat, as well as a count of the number of occurrences of the repeating fields. The following example demonstrates how to define a ModelOutput message containing a variable number of entries for Make, Model, and Color. The total message will be 6004 bytes long and can contain a maximum of 100 60 byte entries of Make, Model, and Color.

   public class ModelOutput extends IMSFieldMessage {

     static DLITypeInfo[] modelTypeInfo = {
           new DLITypeInfo("Make",   DLITypeInfo.CHAR,       1,  20),
           new DLITypeInfo("Model",  DLITypeInfo.CHAR,      21,  20),
           new DLITypeInfo("Color",  DLITypeInfo.CHAR,      41,  20)
     };

     static DLITypeInfo[] modelOutputTypeInfo = {
        new DLITypeInfo     ("ModelCount", DLITypeInfo.INTEGER,  1,  4),
        new DLITypeInfoList ("ModelList",  modelTypeInfo,        5, 60, 100)
     };

     public ModelOutput() {
        super(modelOutputTypeInfo, 6004, false);
     }
   }

Constructor Detail

DLITypeInfoList

public DLITypeInfoList(java.lang.String listName,
                       DLITypeInfo[] typeInfo,
                       int startingOffset,
                       int length,
                       int count)

Constructs a DLITypeInfoList object.

Parameters:

listName - the name of the repeating set of fields

startingOffset - the starting offset in the I/O area of this set of fields, beginning at offset 1

length - the length, in bytes, of one instance of this set of fields

count - the number of times the fields repeat

Throws:

java.lang.IllegalArgumentException - if the starting offset is less than zero, or an invalid length is given
