Constructor Detail

CryptoCacheCipherEntry

protected CryptoCacheCipherEntry(CryptoCacheKeyEntry keyEntry,
                                 String cipherTransformation,
                                 Cipher cipher)

Create a new instance.

Parameters:

keyEntry - the corresponding key-entry. Must not be null.

cipherTransformation - the transformation (as passed to CryptoRegistry.createCipher(String)). Must not be null.

cipher - the cipher. Must not be null.

CryptoCacheCipherEntry

protected CryptoCacheCipherEntry(CryptoCacheKeyEntry keyEntry,
                                 CryptoCacheCipherEntry original)

Create a new instance copying an old one. Used to refresh an existing entry (as it assigns a new lastUsageTimestamp) while keeping this class immutable.

Parameters:

keyEntry - the key-entry.

original - the original from which to copy.

Method Detail

getKeyEntry

public CryptoCacheKeyEntry getKeyEntry()

Get the corresponding key-entry.

Returns:

the corresponding key-entry; never null.

getCipherTransformation

public String getCipherTransformation()

Get the transformation (as passed to CryptoRegistry.createCipher(String)).

Returns:

the transformation (as passed to CryptoRegistry.createCipher(String)); never null.

getCipher

public Cipher getCipher()

Get the cipher.

Returns:

the cipher; never null.

getLastUsageTimestamp

public Date getLastUsageTimestamp()

Get the timestamp when the cipher was used the last time.

Returns:

the timestamp when the cipher was used the last time.
