ASN1Set

public ASN1Set()

Method Detail

getInstance

public static ASN1Set getInstance(Object obj)

return an ASN1Set from the given object.

Parameters:

obj - the object we want converted.

Throws:

IllegalArgumentException - if the object cannot be converted.

getInstance

public static ASN1Set getInstance(ASN1TaggedObject obj,
                                  boolean explicit)

Return an ASN1 set 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 set - 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 sets 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

public Enumeration getObjects()

getObjectAt

public DEREncodable getObjectAt(int index)

return the object at the set postion indicated by index.

Parameters:

index - the set number (starting at zero) of the object

Returns:

the object at the set postion indicated by index.

size

public int size()

return the number of objects in this set.

Returns:

the number of objects in this set.

parser

public ASN1SetParser parser()

hashCode

public int hashCode()

Specified by:

hashCode in class ASN1Object

sort

protected void sort()

addObject

protected void addObject(DEREncodable obj)

toString

public String toString()

Overrides:

toString in class Object
