Class ASN1Integer

java.lang.Object

com.unboundid.asn1.ASN1Element

com.unboundid.asn1.ASN1Integer

All Implemented Interfaces:

java.io.Serializable

@NotMutable
 @ThreadSafety(level=COMPLETELY_THREADSAFE)
public final class ASN1Integer
extends ASN1Element

This class provides an ASN.1 integer element that is backed by a Java int, which is a signed 32-bit value and can represent any integer between -2147483648 and 2147483647. If you need support for integer values in the signed 64-bit range, see the ASN1Long class as an alternative. If you need support for integer values of arbitrary size, see ASN1BigInteger.

Constructor Detail

ASN1Integer

public ASN1Integer(int intValue)

Creates a new ASN.1 integer element with the default BER type and the provided int value.

Parameters:

intValue - The int value to use for this element.

ASN1Integer

public ASN1Integer(byte type,
                   int intValue)

Creates a new ASN.1 integer element with the specified BER type and the provided int value.

Parameters:

type - The BER type to use for this element.

intValue - The int value to use for this element.

Method Detail

intValue

public int intValue()

Retrieves the int value for this element.

Returns:

The int value for this element.

decodeAsInteger

@NotNull
public static ASN1Integer decodeAsInteger(@NotNull
                                                   byte[] elementBytes)
                                            throws ASN1Exception

Decodes the contents of the provided byte array as an integer element.

Parameters:

elementBytes - The byte array to decode as an ASN.1 integer element.

Returns:

The decoded ASN.1 integer element.

Throws:

ASN1Exception - If the provided array cannot be decoded as an integer element.

Decodes the provided ASN.1 element as an integer element.

Parameters:

element - The ASN.1 element to be decoded.

Returns:

The decoded ASN.1 integer element.
