public CRLNumberExtension(int crlNum) throws IOException 
{
        this(PKIXExtensions.CRLNumber_Id, false, BigInteger.valueOf(crlNum),
        NAME, LABEL);
}

Create a CRLNumberExtension with the integer value . The criticality is set to false.

Parameters:

crlNum - the value to be set for the extension.

 public CRLNumberExtension(BigInteger crlNum) throws IOException 
{
        this(PKIXExtensions.CRLNumber_Id, false, crlNum, NAME, LABEL);
}

Create a CRLNumberExtension with the BigInteger value . The criticality is set to false.

Parameters:

crlNum - the value to be set for the extension.

 public CRLNumberExtension(Boolean critical,
    Object value) throws IOException 
{
        this(PKIXExtensions.CRLNumber_Id, critical, value, NAME, LABEL);
}

Create the extension from the passed DER encoded value of the same.

Parameters:

critical - true if the extension is to be treated as critical.

value - an array of DER encoded bytes of the actual value.

Throws:

ClassCastException - if value is not an array of bytes

IOException - on error.

exception: ClassCastException - if value is not an array of bytes

exception: IOException - on error.
