drcl.data
Class Struct

java.lang.Object
  drcl.DrclObj
      drcl.data.Struct

All Implemented Interfaces:

java.lang.Cloneable, ObjectDuplicable, java.io.Serializable

Direct Known Subclasses:

UniversalStruct

public abstract class Struct

extends DrclObj

The class which emulates the "struct" language construct in C. Each field in the struct is referenced by its index, starting from 0. Subclasses must implement getNumFields() and getAllFields() and would implement different setter/getter methods based on the struct format.
