Class BERIntegral
java.lang.Object
|
+--netscape.ldap.ber.stream.BERElement

+--netscape.ldap.ber.stream.BERIntegral
- All Implemented Interfaces:
- java.io.Serializable
- Direct Known Subclasses:
- BEREnumerated, BERInteger
- public abstract class BERIntegral
- extends BERElement
This is the base class for integral types such as Integer and
Enumerated.
ENCODING RULE:
Primitive Definite length.
tag = << depends on type >>
length = (short or long form)
one or more contents octets hold integral value
value in two's complement
Example 1: (Integer - zero)
02 01 00
Example 2: (Enumerated - 1)
0A 01 01
Example 3: (Integer - 300, short form)
02 02 01 2C
Example 4: (Integer - 300, long form)
02 84 00 00 01 2C
