  at.knowcenter.wag.egov.egiz.framework.signators.TextualSignator_1_0_0

All Implemented Interfaces:

Signator

public class TextualSignator_1_0_0
extends Object
implements Signator

Signs a document textually.

In prepareSign, the document text is extracted and normalized.

In finishSign, the signed SignatureObject is transformed into a Signature block, which is then written as an Incremental Update.

Field Summary

static PdfASID

MY_ID The Pdf-AS ID of this Signator.

Constructor Summary

TextualSignator_1_0_0()
Default constructor.

Method Summary

SignResult	finishSign(IncrementalUpdateInformation iui) This is called after the data has been signed by the connector.
IncrementalUpdateInformation	prepareSign(byte[] pdf, String signature_type, TablePos pos, boolean has_SIG_ID) The parameter has_SIG_ID is not used by this Signator because it doesn't pre-format the signature block.

Method Detail

prepareSign

public IncrementalUpdateInformation prepareSign(byte[] pdf,
                                                String signature_type,
                                                TablePos pos,
                                                boolean has_SIG_ID)
                                         throws PresentableException

The parameter has_SIG_ID is not used by this Signator because it doesn't pre-format the signature block.

Specified by:

prepareSign in interface Signator

Parameters:

pdf - The PDF document to be signed.

signature_type - The type/profile of the signature to apply.

pos - The table position. If null, the position is read from the profile, if this is null too, the position is computed.

has_SIG_ID - Tells the algorithm, id a SIG_ID field will be required after signing. Algorithms with fixed formatted signature blocks need to know this.

Returns:

Returns the IncrementalUpdateInformation.

Throws:

PresentableException - Forwarded exception.

finishSign

public SignResult finishSign(IncrementalUpdateInformation iui)
                      throws PresentableException

Description copied from interface: Signator

This is called after the data has been signed by the connector.

Replaces all the left out placeholders with their values retrieved from the signation process.

Specified by:

finishSign in interface Signator

Parameters:

iui - The IncrementalUpdateInformation.

Throws:

PDFDocumentException - Forwarded exception.

PresentableException
