Constructor Detail

ASN1External

public ASN1External(ASN1EncodableVector vector)
Construct an EXTERNAL object, the input encoding vector must have exactly two elements on it.

Acceptable input formats are: ASN1ObjectIdentifier + data DERTaggedObject (direct reference form) ASN1Integer + data DERTaggedObject (indirect reference form) Anything but DERTaggedObject + data DERTaggedObject (data value form)

Throws:
java.lang.IllegalArgumentException - if input size is wrong, or

ASN1External

public ASN1External(ASN1ObjectIdentifier directReference,
                    ASN1Integer indirectReference,
                    ASN1Primitive dataValueDescriptor,
                    DERTaggedObject externalData)
Creates a new instance of External See X.690 for more informations about the meaning of these parameters

Parameters:
directReference - The direct reference or null if not set.
indirectReference - The indirect reference or null if not set.
dataValueDescriptor - The data value descriptor or null if not set.
externalData - The external data in its encoded form.

                    int encoding,
                    ASN1Primitive externalData)
Creates a new instance of External. See X.690 for more informations about the meaning of these parameters

Parameters:
directReference - The direct reference or null if not set.
indirectReference - The indirect reference or null if not set.
dataValueDescriptor - The data value descriptor or null if not set.
encoding - The encoding to be used for the external data
