Class ASN1BigInteger

java.lang.Object
com.unboundid.asn1.ASN1Element
com.unboundid.asn1.ASN1BigInteger
All Implemented Interfaces:
Serializable
@NotMutable @ThreadSafety(level=COMPLETELY_THREADSAFE) public final class ASN1BigInteger extends ASN1Element
This class provides an ASN.1 integer element that is backed by a Java BigInteger and whose value can be represented as an integer of any magnitude. For an ASN.1 integer implementation that is backed by a signed 32-bit int, see ASN1Integer. For an implementation that is backed by a signed 64-bit long, see ASN1Long.
