Method Detail

getInstance

public static ASN1BitString getInstance(java.lang.Object obj)

return a Bit String that can be definite-length encoded from the passed in object.

Parameters:

obj - a DL or DER BitString or an object that can be converted into one.

Returns:

an ASN1BitString instance, or null.

Throws:

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

getInstance

public static ASN1BitString getInstance(ASN1TaggedObject obj,
                                        boolean explicit)

return a Bit String 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 ASN1BitString instance, or null.

Throws:

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