| Name | Description |
|---|---|
| RegisterNatives(JniObjectReference, JniNativeMethodRegistration[]) |
Registers every entry in a managed native method registration array. |
| RegisterNatives(JniObjectReference, ReadOnlySpan<JniNativeMethod>) |
Registers JNI native methods using blittable JniNativeMethod structs with raw function pointers and UTF-8 name/signature pointers. Calls the JNI RegisterNatives function directly without delegate marshaling. |
| RegisterNatives(JniObjectReference, JniNativeMethodRegistration[], Int32) |
Registers a prefix of a managed native method registration array. |
RegisterNatives(JniObjectReference, JniNativeMethodRegistration[])
Registers every entry in a managed native method registration array.
public static void RegisterNatives(Java.Interop.JniObjectReference type, Java.Interop.JniNativeMethodRegistration[] methods);static member RegisterNatives : Java.Interop.JniObjectReference * Java.Interop.JniNativeMethodRegistration[] -> unitParameters
- type
- JniObjectReference
The Java class reference used when there are registrations.
- methods
- JniNativeMethodRegistration[]
The native method registrations, or null for none. Keep their delegates alive for all later JNI callbacks.

RegisterNatives(JniObjectReference, ReadOnlySpan<JniNativeMethod>)
Registers JNI native methods using blittable JniNativeMethod structs with raw function pointers and UTF-8 name/signature pointers. Calls the JNI RegisterNatives function directly without delegate marshaling.
public static void RegisterNatives(Java.Interop.JniObjectReference type, ReadOnlySpan<Java.Interop.JniNativeMethod> methods);static member RegisterNatives : Java.Interop.JniObjectReference * ReadOnlySpan<Java.Interop.JniNativeMethod> -> unitParameters
- type
- JniObjectReference
A valid reference to the Java class that declares the native methods.
- methods
- ReadOnlySpan<JniNativeMethod>
The native method records to register.
Remarks
Name and signature pointers must contain zero-terminated modified UTF-8 and remain valid for this call. Function pointers and their callback targets must remain valid for all later JNI calls. A pending Java exception is converted to a managed exception; a nonzero JNI result without such an exception causes InvalidOperationException.

RegisterNatives(JniObjectReference, JniNativeMethodRegistration[], Int32)
Registers a prefix of a managed native method registration array.
public static void RegisterNatives(Java.Interop.JniObjectReference type, Java.Interop.JniNativeMethodRegistration[] methods, int numMethods);static member RegisterNatives : Java.Interop.JniObjectReference * Java.Interop.JniNativeMethodRegistration[] * int -> unitParameters
- type
- JniObjectReference
The Java class reference used when there are registrations.
- methods
- JniNativeMethodRegistration[]
The native method registrations, or null when the count is zero. Keep their delegates alive for all later JNI callbacks.
- numMethods
- Int32
The number of entries to register from the start of the array, from zero through its length.
