Try to coerce self to type TResult,
checking that the coercion is valid on the Java side.
public static bool TryJavaCast<TResult>(this Java.Interop.IJavaPeerable? self, out TResult? result) where TResult : class, Java.Interop.IJavaPeerable;static member TryJavaCast : Java.Interop.IJavaPeerable * 'Result -> bool (requires 'Result : null and 'Result :> Java.Interop.IJavaPeerable)Type Parameters
- TResult
The type to coerce self to.
Parameters
- self
- IJavaPeerable
A IJavaPeerable instance
to coerce to type TResult.
- result
- TResult
When this method returns, contains a value of type
TResult if self can be
coerced to the Java type corresponding to TResult,
or null if the coercion is not valid.
Returns
true if <pramref name="self"></pramref> was converted successfully;
otherwise, false.
Exceptions
The Java peer type for TResult could not be found.
The type TResult or a Invoker type for
TResult does not provide an
activation constructor, a constructor with a singature of
(ref JniObjectReference, JniObjectReferenceOptions) or
(IntPtr, JniHandleOwnership).
Remarks
<block subset="none" type="note"> Implementations of IJavaPeerable consist of two halves: a Java peer and a managed peer. The PeerReference property associates the managed peer to the Java peer. </block> <block subset="none" type="note"> The JniTypeSignatureAttribute or RegisterAttribute custom attributes are used to associated a managed type to a Java type. </block>
