Class BinarySignator_1_0_0

java.lang.Object
  at.gv.egiz.pdfas.impl.signator.binary.BinarySignator_1_0_0

All Implemented Interfaces:

Signator

Direct Known Subclasses:

BinarySignator_1_1_0

public class BinarySignator_1_0_0

extends Object

implements Signator

Signs the document binary.

In prepareSign, an Incremental Update is created that contains the Signature block and the egiz dictionary. For formatting the layout, variable values are filled with placeholders. After the layout has been fixed, all variable fields (all holes in the byte ranges) are replaced with 0. This document is then base64 encoded and signed.

In finishSign, the variable fields (values, /Cert) are replaced with the values according to the encoding.

Default constructor.

Method Detail

getMyId

public PdfASID getMyId()

Description copied from interface: Signator

Returns the PdfASID of this Connector.

This should always return the MY_ID static field of the connector. Dont't forget to override this.

Within connector code always use this method so that code reuse through derivation can take place correctly.

Specified by:

getMyId in interface Signator

Returns:

Returns the PdfASID of this Connector.
