Pnp​Object Pnp​Object Pnp​Object Pnp​Object Class

Definition

Represents a PnP object. This class allows access to well-known properties of a PnP object as well as a property store of additional properties that are specified to be retrieved from the the PnP object.

Methods

CreateFromIdAsync(PnpObjectType, String, IIterable<String>) CreateFromIdAsync(PnpObjectType, String, IIterable<String>) CreateFromIdAsync(PnpObjectType, String, IIterable<String>) CreateFromIdAsync(PnpObjectType, String, IIterable<String>)

Creates a PnpObject object asynchronously from a previously saved DeviceInformation ID.

public : static IAsyncOperation<PnpObject> CreateFromIdAsync(PnpObjectType type, PlatForm::String id, IIterable<PlatForm::String> requestedProperties)public static IAsyncOperation<PnpObject> CreateFromIdAsync(PnpObjectType type, String id, IEnumerable<String> requestedProperties)Public Static Function CreateFromIdAsync(type As PnpObjectType, id As String, requestedProperties As IEnumerable<String>) As IAsyncOperation( Of PnpObject )// You can use this method in JavaScript.
Parameters
id
PlatForm::String String String String

The string value identifying the PnpObject.

requestedProperties
IIterable<PlatForm::String> IEnumerable<String> IEnumerable<String> IEnumerable<String>

An iterable list of additional properties to include in the Properties property of the PnpObject object to create. For more info on what the properties represent, see Device information properties.

Returns

CreateWatcher(PnpObjectType, IIterable<String>) CreateWatcher(PnpObjectType, IIterable<String>) CreateWatcher(PnpObjectType, IIterable<String>) CreateWatcher(PnpObjectType, IIterable<String>)

Returns a PnpObjectWatcher object that is used to enumerate the PnP objects in the collection using events.

public : static PnpObjectWatcher CreateWatcher(PnpObjectType type, IIterable<PlatForm::String> requestedProperties)public static PnpObjectWatcher CreateWatcher(PnpObjectType type, IEnumerable<String> requestedProperties)Public Static Function CreateWatcher(type As PnpObjectType, requestedProperties As IEnumerable<String>) As PnpObjectWatcher// You can use this method in JavaScript.
Parameters
requestedProperties
IIterable<PlatForm::String> IEnumerable<String> IEnumerable<String> IEnumerable<String>

An iterable list of additional properties to include in the Properties property of the PnpObject objects included in enumeration results. For more info on what the properties represent, see Device information properties.

Returns

A PnpObjectWatcher object used to enumerate the collection by registering event notification delegates and by issuing start and stop event notifications.

Remarks

CreateWatcher is a primary starting point method for enumerating device objects. A client should use this API to enumerate PnpObject s if they want the enumeration to happen incrementally, or if they want the results to be updated as things change. For example, if a PnpObject is added, removed or its properties are updated, the client will register event handlers with the returned watcher object to receive the enumerated PnpObject as well as the later updates.
