Four main reference + * types are provided: local_ref, global_ref, weak_ref, and alias_ref. All are generic + * templates that and refer to objects in the jobject hierarchy. The type of the referred objects + * are specified using the template parameter. All reference types except alias_ref own their + * underlying reference, just as a std smart pointer owns the underlying raw pointer. In the context + * of std smart pointers, these references behave like unique_ptr, and have basically the same + * interface. Thus, when the reference is destructed, the plain JNI reference, i.e. the underlying + * JNI reference (like the parameters passed directly to JNI functions), is released. The alias + * references provides no ownership and is a simple wrapper for plain JNI references. + * + * All but the weak references provides access to the underlying object using dereferencing, and a + * get() method. It is also possible to convert these references to booleans to test for nullity. + * To access the underlying object of a weak reference, the reference must either be released, or + * the weak reference can be used to create a local or global reference. + * + * An owning reference is created either by moving the reference from an existing owned reference, + * by copying an existing owned reference (which creates a new underlying reference), by using the + * default constructor which initialize the reference to nullptr, or by using a helper function. The + * helper function exist in two flavors: make_XXX or adopt_XXX. + * + * Adopting takes a plain JNI reference and wrap it in an owned reference. It takes ownership of the + * plain JNI reference so be sure that no one else owns the reference when you adopt it, and make + * sure that you know what kind of reference it is. + * + * New owned references can be created from existing plain JNI references, alias references, local + * references, and global references (i.e. non-weak references) using the make_local, make_global, + * and make_weak functions. + * + * Alias references can be implicitly initialized using global, local and plain JNI references using + * the wrap_alias function. Here, we don't assume ownership of the passed-in reference, but rather + * create a separate reference that we do own, leaving the passed-in reference to its fate. + * + * Similar rules apply for assignment. An owned reference can be copy or move assigned using a smart + * reference of the same type. In the case of copy assignment a new reference is created. Alias + * reference can also be assigned new values, but since they are simple wrappers of plain JNI + * references there is no move semantics involved. + * + * Alias references are special in that they do not own the object and can therefore safely be + * converted to and from its corresponding plain JNI reference. They are useful as parameters of + * functions that do not affect the lifetime of a reference. Usage can be compared with using plain + * JNI pointers as parameters where a function does not take ownership of the underlying object. + * + * The local, global, and alias references makes it possible to access methods in the underlying + * objects. A core set of classes are implemented in CoreClasses.h, and user defined wrappers are + * supported (see example below). The wrappers also supports inheritance so a wrapper can inherit + * from another wrapper to gain access to its functionality. As an example the jstring wrapper + * inherits from the jobject wrapper, so does the jclass wrapper. That means that you can for + * example call the toString() method using the jclass wrapper, or any other class that inherits + * from the jobject wrapper. + * + * Note that the wrappers are parameterized on the static type of your (jobject) pointer, thus if + * you have a jobject that refers to a Java String you will need to cast it to jstring to get the + * jstring wrapper. This also mean that if you make a down cast that is invalid there will be no one + * stopping you and the wrappers currently does not detect this which can cause crashes. Thus, cast + * wisely. + * + * @include WrapperSample.cpp + */ + +#pragma once + +#include +#include +#include + +#include + +#include + +#include "ReferenceAllocators.h" +#include "TypeTraits.h" +#include "References-forward.h" + +namespace facebook { +namespace jni { + +/// Convenience function to wrap an existing local reference +template +local_ref adopt_local(T ref) noexcept; + +/// Convenience function to wrap an existing global reference +template +global_ref adopt_global(T ref) noexcept; + +/// Convenience function to wrap an existing weak reference +template +weak_ref adopt_weak_global(T ref) noexcept; + + +/// Swaps two owning references of the same type +template +void swap(weak_ref& a, weak_ref& b) noexcept; + +/// Swaps two owning references of the same type +template +void swap(basic_strong_ref& a, basic_strong_ref& b) noexcept; + +/** + * Retrieve the plain reference from a plain reference. + */ +template +enable_if_t(), T> getPlainJniReference(T ref); + +/** + * Retrieve the plain reference from an alias reference. + */ +template +JniType getPlainJniReference(alias_ref ref); + +/** + * Retrieve the plain JNI reference from any reference owned reference. + */ +template +JniType getPlainJniReference(const base_owned_ref& ref); + +class JObject; +class JClass; + +namespace detail { + +template +struct HasJniRefRepr : std::false_type {}; + +template +struct HasJniRefRepr::value, void>::type> : std::true_type { + using type = typename T::JniRefRepr; +}; + +template +struct RefReprType { + using type = typename std::conditional::value, typename HasJniRefRepr::type, JObjectWrapper>::type; + static_assert(std::is_base_of::value, + "Repr type missing JObject base."); + static_assert(std::is_same::type>::value, + "RefReprType not idempotent"); +}; + +template +struct RefReprType::value, void>::type> { + using type = T; + static_assert(std::is_base_of::value, + "Repr type missing JObject base."); + static_assert(std::is_same::type>::value, + "RefReprType not idempotent"); +}; + +template +struct JavaObjectType { + using type = typename RefReprType::type::javaobject; + static_assert(IsPlainJniReference(), + "JavaObjectType not a plain jni reference"); + static_assert(std::is_same::type>::value, + "JavaObjectType not idempotent"); +}; + +template +struct JavaObjectType> { + using type = T; + static_assert(IsPlainJniReference(), + "JavaObjectType not a plain jni reference"); + static_assert(std::is_same::type>::value, + "JavaObjectType not idempotent"); +}; + +template +struct JavaObjectType { + using type = T*; + static_assert(IsPlainJniReference(), + "JavaObjectType not a plain jni reference"); + static_assert(std::is_same::type>::value, + "JavaObjectType not idempotent"); +}; + +template +struct ReprStorage { + explicit ReprStorage(JniType obj) noexcept; + + void set(JniType obj) noexcept; + + Repr& get() noexcept; + const Repr& get() const noexcept; + JniType jobj() const noexcept; + + void swap(ReprStorage& other) noexcept; + private: + ReprStorage() = delete; + ReprStorage(const ReprStorage&) = delete; + ReprStorage(ReprStorage&&) = delete; + ReprStorage& operator=(const ReprStorage&) = delete; + ReprStorage& operator=(ReprStorage&&) = delete; + + using Storage = typename std::aligned_storage::type; + Storage storage_; +}; + +} // namespace detail + +/** + * Create a new local reference from an existing reference + * + * @param ref a plain JNI, alias, or strong reference + * @return an owned local reference (referring to null if the input does) + * @throws std::bad_alloc if the JNI reference could not be created + */ +template +enable_if_t(), local_ref>> +make_local(const T& r); + +/** + * Create a new global reference from an existing reference + * + * @param ref a plain JNI, alias, or strong reference + * @return an owned global reference (referring to null if the input does) + * @throws std::bad_alloc if the JNI reference could not be created + */ +template +enable_if_t(), global_ref>> +make_global(const T& r); + +/** + * Create a new weak global reference from an existing reference + * + * @param ref a plain JNI, alias, or strong reference + * @return an owned weak global reference (referring to null if the input does) + * @throws std::bad_alloc if the returned reference is null + */ +template +enable_if_t(), weak_ref>> +make_weak(const T& r); + +/** + * Compare two references to see if they refer to the same object + */ +template +enable_if_t() && IsNonWeakReference(), bool> +operator==(const T1& a, const T2& b); + +/** + * Compare two references to see if they don't refer to the same object + */ +template +enable_if_t() && IsNonWeakReference(), bool> +operator!=(const T1& a, const T2& b); + +template +class base_owned_ref { + public: + using javaobject = JniType; + + /** + * Release the ownership and set the reference to null.
