    • Method Detail

      • isUpToDate

        public boolean isUpToDate()
                   throws DataAccessException,
                          IllegalPropertyException,
                          GitException
        Returns true if this command is up to date, which means that the internal state (Command.state()) would not change by running (Command.run()) the command again. It other words, when this method returns true any invocation of the (Command.run()) method is needless and idempotent about the state. This method uses the quickest method to verify whether the state is up to date or not. This method must not rely on dependencies and it must always evaluate its own status independently. As a general rule this method checks if its inputs (i.e. from the configuration) have changed since the last run.
        Returns:
        true if this command is up to date
        Throws:
        DataAccessException - in case the configuration can't be loaded for some reason.
        IllegalPropertyException - in case the configuration has some illegal options.
        GitException - in case of unexpected issues when accessing the Git repository.
