Method Detail

getInstance

public static ASN1Integer getInstance(java.lang.Object obj)

return an integer from the passed in object

Parameters:

obj - an ASN1Integer or an object that can be converted into one.

Returns:

an ASN1Integer instance.

Throws:

java.lang.IllegalArgumentException - if the object cannot be converted.

getInstance

public static ASN1Integer getInstance(ASN1TaggedObject obj,
                      boolean explicit)

return an Integer from a tagged object.

Parameters:

obj - the tagged object holding the object we want

explicit - true if the object is meant to be explicitly tagged false otherwise.

Returns:

an ASN1Integer instance.

Throws:

java.lang.IllegalArgumentException - if the tagged object cannot be converted.

getValue

public java.math.BigInteger getValue()

getPositiveValue

public java.math.BigInteger getPositiveValue()

in some cases positive values get crammed into a space, that's not quite big enough...

Returns:

the BigInteger that results from treating this ASN.1 INTEGER as unsigned.

hashCode

public int hashCode()

Specified by:

hashCode in class ASN1Primitive

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
