Bouncy Castle Provider (FIPS Distribution) 1.0.2.5 · org.bouncycastle.asn1.DLSet

The DLSet encodes ASN.1 SET value without element ordering, and always using definite length form.

X.690

8: Basic encoding rules

8.11 Encoding of a set value

8.11.1 The encoding of a set value shall be constructed

8.11.2 The contents octets shall consist of the complete encoding of a data value from each of the types listed in the ASN.1 definition of the set type, in an order chosen by the sender, unless the type was referenced with the keyword OPTIONAL or the keyword DEFAULT.

8.11.3 The encoding of a data value may, but need not, be present for a type which was referenced with the keyword OPTIONAL or the keyword DEFAULT.

NOTE — The order of data values in a set value is not significant, and places no constraints on the order during transfer

9: Canonical encoding rules

9.3 Set components

The encodings of the component values of a set value shall appear in an order determined by their tags as specified in 8.6 of ITU-T Rec. X.680 | ISO/IEC 8824-1. Additionally, for the purposes of determining the order in which components are encoded when one or more component is an untagged choice type, each untagged choice type is ordered as though it has a tag equal to that of the smallest tag in that choice type or any untagged choice types nested within.

10: Distinguished encoding rules

10.3 Set components

The encodings of the component values of a set value shall appear in an order determined by their tags as specified in 8.6 of ITU-T Rec. X.680 | ISO/IEC 8824-1.

NOTE — Where a component of the set is an untagged choice type, the location of that component in the ordering will depend on the tag of the choice component being encoded.

11: Restrictions on BER employed by both CER and DER

11.5 Set and sequence components with default value

The encoding of a set value or sequence value shall not include an encoding for any component value which is equal to its default value.

Constructor Summary

Access	Constructor and Description
public	DLSet() create an empty set
public	DLSet(ASN1Encodable - a single object that makes up the set. obj)
public	DLSet(ASN1EncodableVector - a vector of objects making up the set. v)
public	DLSet(ASN1Encodable[] a) create a set from an array of objects.

Method Summary

Modifier and Type	Method and Description
pack-priv void	encode(ASN1OutputStream out) Implements abstract org.bouncycastle.asn1.ASN1Set.encode. A note on the implementation: As DL requires the constructed, definite-length model to be used for structured types, this varies slightly from the ASN.1 descriptions given.
pack-priv int	encodedLength() Implements abstract org.bouncycastle.asn1.ASN1Primitive.encodedLength. Return the length of the encoding this object will produce.

A note on the implementation: As DL requires the constructed, definite-length model to be used for structured types, this varies slightly from the ASN.1 descriptions given. Rather than just outputting SET, we also have to specify CONSTRUCTED, and the objects length.
