Interface FingerprintOperationResult

All Superinterfaces:

OperationResult

public interface FingerprintOperationResult
extends OperationResult

The FingerprintOperationResult interface is implemented by fingerprint device implementations to communicate the outcome of an operation to the application.

This interface extends OperationResult. It uses the getResultCode() method, inherited from OperationResult, to determine the success or failure of the operation. Specific constants defined within OperationResult are used to represent various outcomes of the operation.

In addition to the operation's completion status, this interface provides a method to retrieve the resulting fingerprint data, if the operation involves capturing or processing a fingerprint.

Method Detail

getFingerprint

Fingerprint getFingerprint(int width,
                           int height)

Retrieves the fingerprint data resulting from the operation. This method is typically called after confirming the operation's success.

Parameters:

width - The width of the bitmap representation of the fingerprint.

height - The height of the bitmap representation of the fingerprint.

Returns:

A Fingerprint object containing the fingerprint data, or null if no fingerprint was captured or processed.
