JNI utility class. Used to wrap Java arrays and ByteBuffer in Unity. Not supported on iOS platform.

JniUtility

Methods

wrapByteArray

Wraps Java byte array byte[].

void easyar_JniUtility_wrapByteArray(void * bytes, bool readOnly, easyar_FunctorOfVoid deleter, easyar_Buffer * * Return)
static std::shared_ptr<Buffer> wrapByteArray(void * bytes, bool readOnly, std::function<void()> deleter)
public static @Nonnull Buffer wrapByteArray(long bytes, boolean readOnly, @Nonnull FunctorOfVoid deleter)
companion object fun wrapByteArray(bytes: Long, readOnly: Boolean, deleter: FunctorOfVoid): Buffer
+ (easyar_Buffer *)wrapByteArray:(void *)bytes readOnly:(bool)readOnly deleter:(void (^)())deleter
public static func wrapByteArray(_ bytes: OpaquePointer?, _ readOnly: Bool, _ deleter: @escaping () -> Void) -> Buffer
public static Buffer wrapByteArray(IntPtr bytes, bool readOnly, Action deleter)

Parameters

bytes IntPtr
readOnly Boolean
deleter Action

Returns

Buffer

wrapBuffer

Wraps the direct buffer in Java's java.nio.ByteBuffer.

void easyar_JniUtility_wrapBuffer(void * directBuffer, easyar_FunctorOfVoid deleter, easyar_Buffer * * Return)
static std::shared_ptr<Buffer> wrapBuffer(void * directBuffer, std::function<void()> deleter)
public static @Nonnull Buffer wrapBuffer(long directBuffer, @Nonnull FunctorOfVoid deleter)
companion object fun wrapBuffer(directBuffer: Long, deleter: FunctorOfVoid): Buffer
+ (easyar_Buffer *)wrapBuffer:(void *)directBuffer deleter:(void (^)())deleter
public static func wrapBuffer(_ directBuffer: OpaquePointer?, _ deleter: @escaping () -> Void) -> Buffer
public static Buffer wrapBuffer(IntPtr directBuffer, Action deleter)

Parameters

directBuffer IntPtr
deleter Action

Returns

Buffer

getDirectBufferAddress

Calls JNIEnv->GetDirectBufferAddress to obtain the raw address of the direct buffer in java.nio.ByteBuffer.

void * easyar_JniUtility_getDirectBufferAddress(void * directBuffer)
static void * getDirectBufferAddress(void * directBuffer)
public static long getDirectBufferAddress(long directBuffer)
companion object fun getDirectBufferAddress(directBuffer: Long): Long
+ (void *)getDirectBufferAddress:(void *)directBuffer
public static func getDirectBufferAddress(_ directBuffer: OpaquePointer?) -> OpaquePointer?
public static IntPtr getDirectBufferAddress(IntPtr directBuffer)

Parameters

directBuffer IntPtr

Returns

IntPtr

newJniGlobalPointer
