Constructor Detail

ASN1Set

protected ASN1Set()

ASN1Set

protected ASN1Set(ASN1Encodable obj)
create a sequence containing one object


ASN1Set

protected ASN1Set(ASN1EncodableVector v,
                  boolean doSort)
create a sequence containing a vector of objects.


ASN1Set

protected ASN1Set(ASN1Encodable[] array,
                  boolean doSort)
create a sequence containing a vector of objects.

Method Detail

getInstance

public static ASN1Set getInstance(java.lang.Object obj)
return an ASN1Set from the given object.

Parameters:
obj - the object we want converted.
Throws:
java.lang.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 implicitly 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:
java.lang.IllegalArgumentException - if the tagged object cannot be converted.

getObjects

public java.util.Enumeration getObjects()

getObjectAt

public ASN1Encodable getObjectAt(int index)
return the object at the set position indicated by index.

Parameters:
index - the set number (starting at zero) of the object
Returns:
the object at the set position indicated by index.

size

public int size()
return the number of objects in this set.

Returns:
the number of objects in this set.

toArray

public ASN1Encodable[] toArray()

parser

public ASN1SetParser parser()

hashCode

public int hashCode()
Specified by:
hashCode in class ASN1Primitive

sort

protected void sort()

toString

public java.lang.String toString()
Overrides:
toString in class java.lang.Object
