Method Detail

getInstance

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

return a Bit String from the passed in object

Parameters:

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

Returns:

a DERBitString instance, or null.

Throws:

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

getInstance

public static DERBitString 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:

a DERBitString instance, or null.

Throws:

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