Creates a new instance of DefaultLicenseParam.

Parameters:

subject - The licensing subject to be returned by getSubject().

keyStoreParam - The key store parameters to be returned by getKeyStoreParam().

cipherParam - The cipher parameters to be returned by getCipherParam().

getCipherParam

public CipherParam getCipherParam()

Description copied from interface: LicenseParam

Returns the cipher configuration parameters for the license manager - null is never returned.

Specified by:

getCipherParam in interface LicenseParam

getKeyStoreParam

public KeyStoreParam getKeyStoreParam()

Description copied from interface: LicenseParam

Returns the keystore configuration parameters for the license manager - null is never returned.

Specified by:

getKeyStoreParam in interface LicenseParam

getPreferences

public Preferences getPreferences()

Description copied from interface: LicenseParam

Returns the preferences node where the encoded licence is stored or should get stored. This method may return null if the license manager is neither used to LicenseManager.install(java.io.File) a license nor to LicenseManager.verify() an installed license.

Note that the preferences node should be globally unique; otherwise, another application could overwrite your license key! Thus, it is recommended to follow Sun's guideline of creating globally unique package names by prefixing them with your globally unique Internet domain. You should then put the main class of your application in this package and return its user preferences node. This is because across platforms you will normally only have write access to the user preferences.

Specified by:

getPreferences in interface LicenseParam

Returns:

The nullable preferences node for persisting the license key.

getSubject

public String getSubject()

Description copied from interface: LicenseParam

Returns the license manager's subject as a descriptive string - null is never returned.

Specified by:

getSubject in interface LicenseParam

Returns:

A string which must compare equal to the "subject" property of the LicenseContent JavaBean. Note that this is public information which may be displayed to the user in a wizard or some other form.
