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.
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()`.
