1.2.2 Simple Types

The DODS simple data types consist of Byte, Int16, UInt16, Int32, UInt32, Float32, Float64, Str and Url. These data types match very closely the corresponding types in C or Fortran. Note that--internally--each of these types uses either the C or C++ representation to hold the value of the object.

These abstract classes are direct descendents of BaseType which contain only their definitions for BaseType's abstract member functions and a single constructor.

Byte

Variables which store bytes. Equivalent to unsigned char on most UNIX workstations.

Int16

Variables which store integer values as 16-bit twos-complement signed integers. Equivalent to int on most 16-bit UNIX workstations.

UInt16

Unsigned integer. A 16-bit unsigned integer value.

Int32

Variables which store integer values as 32-bit twos-complement signed integers. Equivalent to int on most 32-bit UNIX workstations.

UInt32

Unsigned integer. A 32-bit unsigned integer value.

Float32

Variables which store floating point data. Defined as the IEEE 32-bit floating point data type, equivalent to a float in ANSI C.

Float64

Variables which store floating point data. Defined as the IEEE 64-bit floating point data type, equivalent to a double in ANSI C.

Str

Variables which store string information. A DODS string is not a sequence of characters referenced using a pointer (as it is in C), it is represented using a C++ object of the class String.

Url

Variables which store references to network resources. This is a sub-class of Str.
