javacardx.biometry
All Superinterfaces: BioTemplate
The OwnerBioTemplate interface should be implemented by the applet which owns the biometric template. It extends the BioTemplate interface and adds functionality to enroll a reference template.
Since:
2.2.2

void init(byte[] bArray, short offset, short length) throws BioException
Initializes the enrollment of a reference template. This method is also used to update a reference template. It resets the validated flag and, in the update case, uninitializes the previous reference. Note:
A correct enrollment sequence is : init,[update],doFinal.
Calling init and doFinal is mandatory, calling update is optional.
Parameters:bArray - - byte array containing the data of the template
offset - - starting offset in the bArray
length - - byte length of the template data in the bArray
Throws:
BioException - with the following reason codes:
void update(byte[] bArray, short offset, short length) throws BioException
Continues the enrollment of a reference template. This method should only be used if all the input data required for enrollment is not available in one byte array. It can be called several times. Note:
A correct enrollment sequence is : init,[update],doFinal.
Calling init and doFinal is mandatory, calling update is optional.
Parameters:bArray - - byte array containing the data of the template
offset - - starting offset in the bArray
length - - byte length of the template data in the bArray
Throws:
BioException - with the following reason codes:
void doFinal() throws BioException
Finalizes the enrollment of a reference template. Final action of enrollment is to designate a reference template as being complete and ready for use (marks the reference as initialized, resets the try counter and unblocks the reference). This routine may also include some error checking prior to the validation of reference template as ready for use. Note:
A correct enrollment sequence is : init,[update],doFinal.
Calling init and doFinal is mandatory, calling update is optional.
Throws:
BioException - with the following reason codes:
void resetUnblockAndSetTryLimit(byte newTryLimit) throws BioException
Resets the validated flag, unblocks the reference, updates the try limit value and resets the try counter to the try limit value.
Parameters:newTryLimit - - the number of tries allowed before the reference
is blocked. newTryLimit must be at least 1.
Throws:
BioException - with the following reason codes:
