new readonly Asn1Tag _TAG [static]

The _TAG constant describes the universal tag for this data type (UNIVERSAL 2).

Reimplemented from Asn1Type.

long mValue

This public member variable is where the integer value is stored. This is the value that is encoded when one of the encode methods is called. It is also where the decoded result is stored when a Decode method is called.
