Method Details
-
getInstance
return an ASN1Sequence from the given object.- Parameters:
obj
- the object we want converted.- Throws:
IllegalArgumentException
- if the object cannot be converted.
-
getInstance
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.

getObjects
-
parser
-
getObjectAt
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.
-
size
public int size()return the number of objects in this sequence.- Returns:
- the number of objects in this sequence.
