Member Function Documentation

achieve()

ilDatabaseServerIsConnectableObjective::achieve

(

Environment

$environment

)

Objectives can be achieved.

They might add resources to the environment when they have been achieved.

This method needs to be idempotent for a given environment. That means: if this is executed a second time, nothing new should happen. Or the other way round: if the environment already looks like desired, the objective should not take any further actions when this is called.

Exceptions

Implements ILIAS\Setup\Objective.

Here is the call graph for this function:

getHash()

ilDatabaseServerIsConnectableObjective::getHash

(

)

Get a hash for this objective.

The hash of two objectives must be the same, if they are the same objective, with the same config on the same environment, i.e. if the one is achieved the other is achieved as well because they are the same.

Implements ILIAS\Setup\Objective.
