Method Summary

Modifier and Type	Method	Description
boolean	run(@Nullable MemorySegment a, @Nullable MemorySegment b)	Specifies the type of a function used to test two values for equality.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment) method.
default int	upcall(MemorySegment a, MemorySegment b)	The upcall method is called from native code.

Method Details

run

boolean run(@Nullable MemorySegment a,
 @Nullable MemorySegment b)

Specifies the type of a function used to test two values for equality. The function should return true if both values are equal and false otherwise.

Parameters:

a - a value

b - a value to compare with

Returns:

true if a = b; false otherwise

upcall

default int upcall(MemorySegment a,
 MemorySegment b)

The upcall method is called from native code. The parameters are marshaled and run(MemorySegment, MemorySegment) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(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
