Method Detail

insertFingerprint

public void insertFingerprint(int id,
                              com.griaule.grfingerjava.Template data)

This method is for inserting single fingerprint. It gets id for the fingerprint and Template object. We will use this to make new FingerprintCacheData object. Which is then inserted into cache. If cache isn't initialized yet we will create a new cache object.

Parameters:

id -

data -

deleteFingerprint

public boolean deleteFingerprint(int id)

This method deletes the fingerprint marked by id from cache.

Parameters:

id -

loadCache

public void loadCache(FingerprintCacheData[] data)

This method (re)loads fingerprints in the cache. If cache isn't empty it's emptied or if it's not initialized it's created. Vector is also sized according to how many fingerprints we are adding and also the initial size is added to the Vector size so that it will accomodate new fingerprints if needed.

Parameters:

data -

getNextFingerprint

public FingerprintCacheData getNextFingerprint()

This method is used to get fingerprints from the cache for comparison.

Returns:

FingerprintCacheData or null if we have gone trough all prints.

resetIterator

public void resetIterator()

This method resets cacheiterator back into the beginning when we start to look for a fingerprint.
