initialize

protected void initialize(LicenseContent content)

Description copied from class: LicenseManager

Overrides:

initialize in class LicenseManager

See Also:

LicenseManager.validate(LicenseContent)

setLicenseParam

public void setLicenseParam(LicenseParam param)

Sets the license configuration parameters. Calling this method resets the manager as if it had been newly created. The implementation of this class asserts that the given parameter object is an instance of LicenseParam and applies some plausibility checks to it to ensure that it adheres to the contract of the parameter interfaces.

Overrides:

setLicenseParam in class LicenseManager

Parameters:

param - The license configuration parameters - may not be null.

Throws:

ClassCastException - if param is not an instance of LicenseParam.

NullPointerException - If the given parameter object does not obey the contract of its interface due to a null pointer.

IllegalPasswordException - If any password in the parameter object does not comply to the current policy.

setLicenseParam0

private void setLicenseParam0(LicenseParam param)

protected LicenseContent verify(LicenseNotary notary)
                         throws Exception

Description copied from class: LicenseManager

Decrypts, decompresses, decodes and verifies the current license key, validates its license content and returns it.

Overrides:

verify in class LicenseManager

Parameters:

notary - the license notary used to verify the current license key - may not be null.

Returns:

A clone of the verified and validated content of the license key - null is never returned.

Throws:

NoLicenseInstalledException - if no license key is installed.

Exception - for any other reason. Note that you should always use Throwable.getLocalizedMessage() to get a (possibly localized) meaningful detail message.
