Method Summary

Modifier and Type	Method	Description
void	run(Logger logger, LoggerLogLevel level, byte direction, String data)	The prototype for a custom printing callback.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, int, byte, MemorySegment, MemorySegment) method.
default void	upcall(MemorySegment logger, int level, byte direction, MemorySegment data, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

void run(Logger logger,
 LoggerLogLevel level,
 byte direction,
 String data)

The prototype for a custom printing callback.

level indicates what kind of information is being printed. Eg, it will be LoggerLogLevel.HEADERS if data is header data.

direction is either '<', '>', or ' ', and data is the single line to print; the printer is expected to add a terminating newline.

To get the effect of the default printer, you would do:

printf ("%c %s\\n", direction, data);

Parameters:

logger - the SoupLogger

level - the level of the information being printed.

direction - a single-character prefix to data

data - data to print

upcall

default void upcall(MemorySegment logger,
 int level,
 byte direction,
 MemorySegment data,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(Logger, LoggerLogLevel, byte, String) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, int, byte, MemorySegment, MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the arena in which the function pointer is allocated

Returns:

the native function pointer
