Class DetachedfTextualSignator_1_0_0

java.lang.Object
  at.knowcenter.wag.egov.egiz.framework.signators.DetachedfTextualSignator_1_0_0

All Implemented Interfaces:

Signator

public class DetachedfTextualSignator_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 String	MIME_TYPE The Mime Type.
static PdfASID	MY_ID The Pdf-AS ID of this Signator.

Constructor Summary

DetachedfTextualSignator_1_0_0()
Default constructor.

Method Summary

SignResult	finishSign(IncrementalUpdateInformation iui) This is called after the data has been signed by the connector.
PdfASID	getMyId() Returns the PdfASID of this Connector.
IncrementalUpdateInformation	prepareSign(PdfDataSource 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.

Constant Field Values

MY_ID

public static final PdfASID MY_ID

The Pdf-AS ID of this Signator.

Constructor Detail

DetachedfTextualSignator_1_0_0

public DetachedfTextualSignator_1_0_0()

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.

Signator.getMyId()

prepareSign

public IncrementalUpdateInformation prepareSign(PdfDataSource 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:

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:

PresentableException
