@PublicAPI(stability=UNCOMMITTED, mayInstantiate=true, mayExtend=false, mayInvoke=true) public final class ASN1Long
This class defines the data structures and methods to use when interacting
with ASN.1 integer elements that may need to hold values greater than will
fit in the scope of a Java int
structure.
Note that the difference between the ASN1Integer
and
ASN1Long
classes is purely artificial. The ASN.1 specification
does not define any size limits for integer values, but the
ASN1Integer
class uses an int
data type behind the
scenes and therefore is only capable of representing values up to
231 - 1 (a little over two billion). This class uses a
long
data type behind the scenes and therefore is capable of
holding much larger values. Because of the need to deal with larger values,
this class may have a small performance disadvantage over the
ASN1Integer
class and therefore that class should be used for
cases in which there is no danger of overflowing an int
value.
