Interface Summary

Interface	Description
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

Class	Description
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.
CallbackReference.AttachOptions
CallbackResultContext	Conversion context from a Java Callback result to a native value.
CallbackThreadInitializer
DefaultTypeMapper	Provide custom mappings to and from native types.
ELFAnalyser	Analyse an ELF file for platform specific attributes.
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
Structure.StructField
Structure.StructureSet	Avoid using a hash-based implementation since the hash code for a Structure is not immutable.
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.
VarArgsChecker	Class for checking if a method has vararg parameters.
WeakMemoryHolder	Helper to hold a memory object based on the lifetime of another object.
WString	Simple wrapper class to identify a wide string argument or return type.

Exception Summary

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