Class ASN1Null

java.lang.Object
  schemajic.model.ASN1Value
      schemajic.model.ASN1Null

Direct Known Subclasses:

NullParms

public class ASN1Null
extends ASN1Value

Models the abstract concept of the value of ASN.1 type NULL.

Type NULL is a simple builtin type whose single distinguished value is also called NULL. This value is often used to indicate that there is no value, which frequently leads to confusion, since under some encoding rules, the NULL value will be present in an instance of communication, perhaps as the tag 0x05 and the length 0x00 in TLV (Tag-Length-Value) encodings.

Universal class tag assignment is UNIVERSAL 5.

XML ASN.1 type name is NULL.
