Method Detail

addObject

protected void addObject(DEREncodable obj)

getInstance

public static ASN1Sequence getInstance(Object obj)

return an ASN1Sequence from the given object.

Parameters: obj the object we want converted.

Throws: IllegalArgumentException if the object cannot be converted.

getInstance

public static ASN1Sequence getInstance(ASN1TaggedObject obj, boolean explicit)

Return an ASN1 sequence from a tagged object. There is a special case here, if an object appears to have been explicitly tagged on reading but we were expecting it to be implictly tagged in the normal course of events it indicates that we lost the surrounding sequence - so we need to add it back (this will happen if the tagged object is a sequence that contains other sequences). If you are dealing with implicitly tagged sequences you really should be using this method.

Parameters: obj the tagged object. explicit true if the object is meant to be explicitly tagged, false otherwise.

Throws: IllegalArgumentException if the tagged object cannot be converted.

getObjectAt

public DEREncodable getObjectAt(int index)

return the object at the sequence postion indicated by index.

Parameters: index the sequence number (starting at zero) of the object

Returns: the object at the sequence postion indicated by index.

Returns: the number of objects in this sequence.

toString
