Method Summary

Modifier and Type	Method	Description
boolean	run(String fileContents, long fileSize, @Nullable MemorySegment callbackData)	When loading the partial contents of a file with g_file_load_partial_contents_async(), it may become necessary to determine if any more data from the file should be loaded.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, long, java.lang.foreign.MemorySegment) method.
default int	upcall(MemorySegment fileContents, long fileSize, MemorySegment callbackData)	The upcall method is called from native code.

Method Details

run

boolean run(String fileContents,
 long fileSize,
 @Nullable
 @Nullable MemorySegment callbackData)

When loading the partial contents of a file with g_file_load_partial_contents_async(), it may become necessary to determine if any more data from the file should be loaded. A GFileReadMoreCallback function facilitates this by returning true if more data should be read, or false otherwise.

upcall

default int upcall(MemorySegment fileContents,
 long fileSize,
 MemorySegment callbackData)

The upcall method is called from native code. The parameters are marshaled and run(java.lang.String, long, java.lang.foreign.MemorySegment) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(java.lang.foreign.MemorySegment, long, java.lang.foreign.MemorySegment) method.

Specified by:

toCallback in interface FunctionPointer

Parameters:

arena - the function pointer will be allocated in this arena

Returns:

the native function pointer
