Method Detail

getInstance

public static ASN1Integer getInstance(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:

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:

IllegalArgumentException - if the tagged object cannot be converted.

getValue

public BigInteger getValue()

getPositiveValue

public 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()

Description copied from class: Object

Returns an integer hash code for this object. By contract, any two objects for which Object.equals(java.lang.Object) returns true must return the same hash code value. This means that subclasses of Object usually override both methods or neither method.

Note that hash values must not change over time unless information used in equals comparisons also changes.

See Writing a correct hashCode method if you intend implementing your own hashCode method.

Specified by:

hashCode in class ASN1Primitive

Returns:

this object's hash code.

Object.equals(java.lang.Object)

toString

public String toString()

Description copied from class: Object

Returns a string containing a concise, human-readable description of this object. Subclasses are encouraged to override this method and provide an implementation that takes into account the object's type and data. The default implementation is equivalent to the following expression:

   getClass().getName() + '@' + Integer.toHexString(hashCode())

See Writing a useful toString method if you intend implementing your own toString method.

Overrides:

toString in class Object

Returns:

a printable representation of this object.
