Examples of FunctionMapper

com.sun.jna.FunctionMapper
Provides mapping of Java method names to native function names. An instance of this interface may be provided to {@link Native#loadLibrary(String,Class,java.util.Map)} as an entry inthe options map with key {@link Library#OPTION_FUNCTION_MAPPER}.
There are several circumstances where this option might prove useful.
- C preprocessor macros are used to allow C code to refer to a library function by a different name
- Generated linker symbols are different than those used in C code. Windows stdcall functions, for instance, are exported with a special suffix that describes the stack size of the function arguments (see {@link com.sun.jna.win32.StdCallFunctionMapper}).
- The naming of the C library methods conflicts horribly with your Java coding standards, or are otherwise hard to follow. It's generally better to keep the original function names in this case, to avoid confusion about what's actually being called, but the option is available.
@see Library#OPTION_FUNCTION_MAPPER
javax.el.FunctionMapper
The interface to a map between EL function names and methods.
A FunctionMapper maps ${prefix:name()} style functions to a static method that can execute that function.
@since JSP 2.1
javax.servlet.jsp.el.FunctionMapper
An implementation of the function mapper.
jnr.ffi.mapper.FunctionMapper
org.zkoss.xel.FunctionMapper
Used to customize the way to map between the XEL function names and the {@link Function} methods. @author tomyeh @since 3.0.0
