Class GenericSignature

java.lang.Object

net.named_data.jndn.Signature

net.named_data.jndn.GenericSignature

All Implemented Interfaces:

ChangeCountable

public class GenericSignature
extends Signature

A GenericSignature extends Signature and holds the encoding bytes of the SignatureInfo so that the application can process experimental signature types. When decoding a packet, if the type of SignatureInfo is not recognized, the library creates a GenericSignature.

Constructor Detail

GenericSignature

public GenericSignature()

Create a new GenericSignature with default values.

GenericSignature

public GenericSignature(GenericSignature signature)

Create a new GenericSignature with a copy of the fields in the given signature object.

Parameters:

signature - The signature object to copy.

Method Detail

clone

public Object clone()
             throws CloneNotSupportedException

Return a new GenericSignature which is a deep copy of this GenericSignature.

Specified by:

clone in class Signature

Returns:

A new GenericSignature.

Throws:

CloneNotSupportedException

getSignatureInfoEncoding

public final Blob getSignatureInfoEncoding()

Get the bytes of the entire signature info encoding (including the type code).

Returns:

The encoding bytes. If not specified, the value isNull().

setSignatureInfoEncoding

public final void setSignatureInfoEncoding(Blob signatureInfoEncoding,
                                           int typeCode)

Set the bytes of the entire signature info encoding (including the type code).

Parameters:

signatureInfoEncoding - A Blob with the encoding bytes.

typeCode - the type code of the signature type, or -1 if not known. (When a GenericSignature is created by wire decoding, it sets the typeCode.)

setSignatureInfoEncoding

public final void setSignatureInfoEncoding(Blob signatureInfoEncoding)

Set the bytes of the entire signature info encoding (including the type code). getTypeCode() will return -1 for not known.

Parameters:

signatureInfoEncoding - A Blob with the encoding bytes.

getSignature

public final Blob getSignature()

Get the signature bytes.

Specified by:

getSignature in class Signature

Returns:

The signature bytes. If not specified, the value isNull().

setSignature

public final void setSignature(Blob signature)

Set the signature bytes to the given value.

Specified by:

setSignature in class Signature

Parameters:

signature - A Blob with the signature bytes.

getTypeCode

public final int getTypeCode()

Get the type code of the signature type. When wire decode calls setSignatureInfoEncoding, it sets the type code. Note that the type code is ignored during wire encode, which simply uses getSignatureInfoEncoding() where the encoding already has the type code.

Returns:

The type code, or -1 if not known.

getChangeCount

public final long getChangeCount()

Get the change count, which is incremented each time this object (or a child object) is changed.

Specified by:

getChangeCount in interface ChangeCountable

Specified by:

getChangeCount in class Signature

Returns:

The change count.
