Constructor Detail

ApplicationConfigurationLicenseStore

public ApplicationConfigurationLicenseStore(com.atlassian.config.ApplicationConfiguration store,
                                            com.atlassian.extras.api.LicenseManager manager)

Method Detail

install

public void install(String licenseString)

This delegates to ApplicationConfiguration.setProperty(Object, Object) but the underlying code does not call ApplicationConfiguration.save() and is thus only in memory for the time being.

This method does not allow concurrent invocation, thus escaping if one was detected. The reason being is that a concurrent license installation could lead to unexpected behaviour, thus we let the first invocation win and encourage the second one to be re-evaluated before being attempted again.

licenseString - the encrypted license
