com.unboundid.asn1.ASN1Element

com.unboundid.asn1.ASN1BigInteger

All Implemented Interfaces:

java.io.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.

Method Detail

getBigIntegerValue

@NotNull
public java.math.BigInteger getBigIntegerValue()

Retrieves the value for this element as a Java BigInteger.

Returns:

The value for this element as a Java BigInteger.

decodeAsBigInteger

@NotNull
public static ASN1BigInteger decodeAsBigInteger(@NotNull
                                                         byte[] elementBytes)
