JniUtility Class¶
Description¶
JNI工具类。
用于在Unity中对Java的数组和ByteBuffer进行包装。
不支持iOS平台。
wrapByteArray¶
包装Java的字节数组byte[]。
- C
void easyar_JniUtility_wrapByteArray(void * bytes, bool readOnly, easyar_FunctorOfVoid deleter, easyar_Buffer * * Return)
- C++17
static std::shared_ptr<Buffer> wrapByteArray(void * bytes, bool readOnly, std::function<void()> deleter)
- C++03
static void wrapByteArray(void * bytes, bool readOnly, FunctorOfVoid deleter, Buffer * * Return)
- Java
public static @Nonnull Buffer wrapByteArray(long bytes, boolean readOnly, @Nonnull FunctorOfVoid deleter)
- Kotlin
companion object fun wrapByteArray(bytes: Long, readOnly: Boolean, deleter: FunctorOfVoid): Buffer
- Objective-C
+ (easyar_Buffer *)wrapByteArray:(void *)bytes readOnly:(bool)readOnly deleter:(void (^)())deleter
- Swift
public static func wrapByteArray(_ bytes: OpaquePointer?, _ readOnly: Bool, _ deleter: @escaping () -> Void) -> Buffer
- C#
public static Buffer wrapByteArray(IntPtr bytes, bool readOnly, Action deleter)
wrapBuffer¶
包装Java的java.nio.ByteBuffer中的direct buffer。
- C
void easyar_JniUtility_wrapBuffer(void * directBuffer, easyar_FunctorOfVoid deleter, easyar_Buffer * * Return)
- C++17
static std::shared_ptr<Buffer> wrapBuffer(void * directBuffer, std::function<void()> deleter)
- C++03
static void wrapBuffer(void * directBuffer, FunctorOfVoid deleter, Buffer * * Return)
- Java
public static @Nonnull Buffer wrapBuffer(long directBuffer, @Nonnull FunctorOfVoid deleter)
- Kotlin
companion object fun wrapBuffer(directBuffer: Long, deleter: FunctorOfVoid): Buffer
- Objective-C
+ (easyar_Buffer *)wrapBuffer:(void *)directBuffer deleter:(void (^)())deleter
- Swift
public static func wrapBuffer(_ directBuffer: OpaquePointer?, _ deleter: @escaping () -> Void) -> Buffer
- C#
public static Buffer wrapBuffer(IntPtr directBuffer, Action deleter)
getDirectBufferAddress¶
调用JNIEnv->GetDirectBufferAddress获得java.nio.ByteBuffer中的direct buffer的原始地址。
- C
void * easyar_JniUtility_getDirectBufferAddress(void * directBuffer)
- C++17
static void * getDirectBufferAddress(void * directBuffer)
- C++03
static void * getDirectBufferAddress(void * directBuffer)
- Java
public static long getDirectBufferAddress(long directBuffer)
- Kotlin
companion object fun getDirectBufferAddress(directBuffer: Long): Long
- Objective-C
+ (void *)getDirectBufferAddress:(void *)directBuffer
- Swift
public static func getDirectBufferAddress(_ directBuffer: OpaquePointer?) -> OpaquePointer?
- C#
public static IntPtr getDirectBufferAddress(IntPtr directBuffer)
newJniGlobalPointer¶
获得Java对象在JNI中的全局指针。
- Java
public static long Buffer newJniGlobalPointer(java.lang.@Nonnull Object obj)
- Kotlin
companion object fun newJniGlobalPointer(obj: java.lang.Object): Long
deleteJniGlobalPointer¶
释放Java对象在JNI中的全局指针。
- Java
public static long Buffer newJniGlobalPointer(java.lang.@Nonnull Object obj)
- Kotlin
companion object fun newJniGlobalPointer(obj: java.lang.Object): Long
