dependsOnEngine()

ilBadgePictureMachine::dependsOnEngine

(

)

Return the class name of the Engine that is required for this Machine to work.

Returning null will result in a NullEngine passed to the Machine.

Implements ILIAS\ResourceStorage\Flavour\Machine\FlavourMachine.

Here is the call graph for this function:

getId()

ilBadgePictureMachine::getId

(

)

Returns

string max. 64 characters, MUST be unique and NOT a class-related magic-constant. E.g. you can generate a random one with $ php -r"echo hash('sha256', uniqid());" | pbcopy in your shell and paste string in your getId() implementation.

If you ever change the ID, FlavourDefinitions may no longer process anything with your machine that previously designated you as the processing machine.

Implements ILIAS\ResourceStorage\Flavour\Machine\FlavourMachine.
