CallNonvirtualFloatMethod(IntPtr, IntPtr, IntPtr)

Calls a Java instance method that returns a Java float, selecting its implementation from the specified class.

public static float CallNonvirtualFloatMethod(IntPtr jobject, IntPtr jclass, IntPtr jmethod);

static member CallNonvirtualFloatMethod : nativeint * nativeint * nativeint -> single

Parameters

jobject: IntPtr
nativeint

A live, non-null JNI object reference from the current VM, usable on the calling thread until the call returns or throws.

jclass: IntPtr
nativeint

A live, non-null JNI class reference for the object's class or one of its supertypes, usable on the calling thread until the call returns or throws.

jmethod: IntPtr
nativeint

A live instance method ID obtained for jclass. Its JNI signature must take no arguments and return a Java float. Keep its declaring class live.

Returns

Single

The value returned by the Java method.

CallNonvirtualFloatMethod(IntPtr, IntPtr, IntPtr, JValue*)

Calls a Java instance method that returns a Java float, selecting its implementation from the specified class.

public static float CallNonvirtualFloatMethod(IntPtr jobject, IntPtr jclass, IntPtr jmethod, Android.Runtime.JValue* parms);

static member CallNonvirtualFloatMethod : nativeint * nativeint * nativeint * nativeptr<Android.Runtime.JValue> -> single

Parameters

jobject: IntPtr
nativeint

A live, non-null JNI object reference from the current VM, usable on the calling thread until the call returns or throws.

jclass: IntPtr
nativeint

A live, non-null JNI class reference for the object's class or one of its supertypes, usable on the calling thread until the call returns or throws.

jmethod: IntPtr
nativeint

A live instance method ID obtained for jclass. Its JNI signature must match the arguments and return a Java float. Keep its declaring class live.

parms: JValue*

A pointer to the arguments in JNI order and types. The storage must be readable for the argument count. Do not change the storage during the call, and keep referenced objects live.

Returns

Single

The value returned by the Java method.
