IceGrid.NodeObserverPrx

class IceGrid.NodeObserverPrx

Bases: ObjectPrx

Monitors changes to the state of the nodes.

Notes

The Slice compiler generated this proxy class from Slice interface ::IceGrid::NodeObserver.

static checkedCast(proxy: ObjectPrx | None, facet: str | None = None, context: dict[str, str] | None = None) → NodeObserverPrx | None

Creates a new proxy from an existing proxy after confirming the target object’s type via a remote invocation.

Parameters:

• proxy (ObjectPrx | None) – The source proxy.

• facet (str, optional) – A facet name.

• context (dict[str, str], optional) – The request context.

Returns:

A new proxy with the requested type, or None if the source proxy is None or if the target object does not support the requested type.

Return type:

ObjectPrx | None

static checkedCastAsync(proxy: ObjectPrx | None, facet: str | None = None, context: dict[str, str] | None = None) → Awaitable[NodeObserverPrx | None]

Parameters:

• proxy (ObjectPrx | None) – The source proxy.

• facet (str, optional) – A facet name.

• context (dict[str, str], optional) – The request context.

Returns:

A new proxy with the requested type, or None if the source proxy is None or if the target object does not support the requested type.

Return type:

ObjectPrx | None
