Static methods

isOpen

Checks if all components are opened.

To be checked, components must implement the IOpenable interface. If they don’t, the call to this method returns true.

static bool isOpen(List? components)

components: List? - list of components that are to be checked.
returns: bool - true if all components are opened and false if at least one component is closed.

isOpenOne

Checks if a specified component is opened. To be checked, components must implement the IOpenable interface. If they don’t, the call to this method returns true.

static bool isOpenOne(component)

component: dynamic - component that is to be checked.
returns: bool - true if the component is opened and false otherwise.

open

Opens multiple components. To be opened, components must implement IOpenable interface. If they don’t, the call to this method has no effect.

static Future open(IContext? context, List? components)

context: IContext - (optional) a context to trace execution through a call chain.
components: List? - list of components that are to be closed.

openOne

Opens a specific component. To be opened, components must implement the IOpenable interface. If they don’t, the call to this method has no effect.

static Future openOne(IContext? context, component)

context: IContext - (optional) a context to trace execution through a call chain.
component: dynamic - component that is to be opened.
