Constructor Detail

ASN1Sequence

protected ASN1Sequence()

create an empty sequence

ASN1Sequence

protected ASN1Sequence(ASN1Encodable obj)

create a sequence containing one object

ASN1Sequence

protected ASN1Sequence(ASN1EncodableVector v)

create a sequence containing a vector of objects.

ASN1Sequence

protected ASN1Sequence(ASN1Encodable[] array)

create a sequence containing a vector of objects.

Method Detail

getInstance

public static ASN1Sequence getInstance(java.lang.Object obj)

return an ASN1Sequence from the given object.

Parameters:

obj - the object we want converted.

Throws:

java.lang.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 implicitly 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:

java.lang.IllegalArgumentException - if the tagged object cannot be converted.

toArray

public ASN1Encodable[] toArray()

getObjects

public java.util.Enumeration getObjects()

parser

public ASN1SequenceParser parser()

getObjectAt

public ASN1Encodable getObjectAt(int index)

return the object at the sequence position indicated by index.

Parameters:

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

Returns:

the object at the sequence position indicated by index.

size

public int size()

return the number of objects in this sequence.

Returns:

the number of objects in this sequence.

hashCode

public int hashCode()

Specified by:

hashCode in class ASN1Primitive

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
