Osnovne usluge

ovdje možeš pronaći API za usluge koje su povezane s izradom i manipulacijom modela.

Repozitorij elemenata (/Factory)

class gaphor.core.modeling.ElementFactory(event_manager: EventManager | None = None, element_dispatcher: ElementDispatcher | None = None)

The ElementFactory is used as a central repository for a model.

New model elements should be created by create.

Methods like select can be used to find elements in the model.

select(expression: Callable[[Base], bool]) → Iterator[Base]

select(expression: type[T]) → Iterator[T]

select(expression: None) → Iterator[Base]

Iterate elements that comply with expression.

Izrazi mogu biti:

• None: return all elements.

• Jedna vrsta: vrati sve elemente te vrste ili njenih podvrsta.

• Jedan izraz.

lselect(expression: Callable[[Base], bool] | type[T] | None = None) → list[Base]

Like select, but return a list, instead of an iterator.

lookup(id: str) → Base | None

Find element with a specific id.

keys() → Iterator[str]

Iterate all id’s in the factory.

values() → Iterator[Base]

Iterate all elements in the factory.

size() → int

Return the amount of elements currently in the factory.

is_empty() → bool

Returns True if the factory holds no elements.

create(type: type[T]) → T

Create a new model element of type type.

This method will only create model elements, not Presentation elements: those are created by Diagram.

flush() → None

Flush all elements (remove them from the factory).

Diagram elements are flushed first. The remaining elements are flushed next.
