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
