Description

Interface Summary
AltCallingConvention	Tagging interface to indicate the library or callback uses an alternate calling convention.
Callback	All callback definitions must derive from this interface.
Callback.UncaughtExceptionHandler
CallbackProxy	Placeholder proxy interface to allow an InvocationHandler to convert arguments/return values on callback methods.
FromNativeConverter	Define conversion from a native type to the appropriate Java type.
Function.PostCallRead	Any argument which implements this interface will have the `Function.PostCallRead.read()` method called immediately after function invocation.
FunctionMapper	Provides mapping of Java method names to native function names.
InvocationMapper	Provide a method for overriding how a given function is invoked.
Library	Derive from this interface for all native library definitions.
Native.ffi_callback
NativeMapped	Provide conversion for a Java type to and from a native type.
Structure.ByReference	Tagging interface to indicate the address of an instance of the Structure type is to be used within a `Structure` definition rather than nesting the full Structure contents.
Structure.ByValue	Tagging interface to indicate the value of an instance of the `Structure` type is to be used in function invocations rather than its address.
ToNativeConverter	Define conversion from a Java type to its corresponding native type.
TypeConverter	Convenience interface for bidirectional conversion.
TypeMapper	Provides converters for conversion to and from native types.

Class Summary
CallbackParameterContext	Provide argument conversion context for a callback invocation.
CallbackReference	Provides a reference to an association between a native callback closure and a Java `Callback` closure.
CallbackResultContext	Conversion context from a Java `Callback` result to a native value.
DefaultTypeMapper	Provide custom mappings to and from native types.
FromNativeContext	Provides context for converting a native value into a Java type.
Function	An abstraction for a native function pointer.
FunctionParameterContext
FunctionResultContext	Provide result conversion context for a function call.
IntegerType	Represents a native integer value, which may have a platform-specific size (e.g.
Library.Handler
Memory	A `Pointer` to memory obtained from the native heap via a call to `malloc`.
MethodParameterContext
MethodResultContext	Provide result conversion context for a function call that is called via a Library interface.
Native	Provides generation of invocation plumbing for a defined native library interface.
Native.DeleteNativeLibrary	For internal use only.
NativeLibrary	Provides management of native library resources.
NativeLong	Represents the `long` C data type, which may be 32 or 64 bits on *nix-based systems.
NativeMappedConverter	Provides type conversion for instances of `NativeMapped`.
NativeString	Provides a temporary allocation of an immutable C string (`const char` or `const wchar_t`) for use when converting a Java String into a native memory function argument.
Platform	Provide simplified platform information.
Pointer	An abstraction for a native pointer data type.
PointerType	Type representing a type-safe native pointer.
StringArray	Handle native array of `char` or `wchar_t` type by managing allocation/disposal of native strings within an array of pointers.
Structure	Represents a native structure with a Java peer class.
Structure.FFIType	This class auto-generates an ffi_type structure appropriate for a given structure for use by libffi.
Structure.FFIType.size_t
StructureReadContext	Provide native to Java type conversion context for a `Structure` field read.
StructureWriteContext	Provide Java to native type conversion context for a `Structure` field write.
ToNativeContext	Context for converting a Java value to a native one.
Union	Represents a native union.
WString	Simple wrapper class to identify a wide string argument or return type.

Exception Summary
LastErrorException	Exception representing a non-zero error code returned in either `errno` or `GetLastError()`.
