| InitializeHandle(NativeHandle, String, Boolean) |
Initializes the Handle property with the result of a native initializer. |
InitializeHandle(NativeHandle)
protected void InitializeHandle(ObjCRuntime.NativeHandle handle);member this.InitializeHandle : ObjCRuntime.NativeHandle -> unitParameters
- handle
- NativeHandle
Applies to
InitializeHandle(NativeHandle, String)
protected void InitializeHandle(ObjCRuntime.NativeHandle handle, string initSelector);member this.InitializeHandle : ObjCRuntime.NativeHandle * string -> unitParameters
- handle
- NativeHandle
- initSelector
- String
Applies to
InitializeHandle(NativeHandle, String, Boolean)
Initializes the Handle property with the result of a native initializer.
protected internal void InitializeHandle(ObjCRuntime.NativeHandle handle, string initSelector, bool throwOnInitFailure);member this.InitializeHandle : ObjCRuntime.NativeHandle * string * bool -> unitParameters
- handle
- NativeHandle
The handle returned by the native initializer.
- initSelector
- String
The selector of the native initializer that produced handle. Only used in the exception message when initialization fails.
- throwOnInitFailure
- Boolean
If true, an exception is thrown when the native initializer failed (returned nil); if false, the Handle property is set to the (possibly null) handle without throwing.
Remarks
Pass false for throwOnInitFailure to implement a factory method for a failable initializer: this makes it possible to detect a nil result (by checking the Handle property) and return null instead of throwing. This is what the generator does for constructors annotated with [FactoryMethod].
