Method Summary

Modifier and Type	Method	Description
File	run(Vfs vfs, String identifier)	This function type is used by g_vfs_register_uri_scheme() to make it possible for a client to associate a URI scheme to a different GFile implementation.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment) method.
default MemorySegment	upcall(MemorySegment vfs, MemorySegment identifier, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

File run(Vfs vfs,
 String identifier)

This function type is used by g_vfs_register_uri_scheme() to make it possible for a client to associate a URI scheme to a different GFile implementation.

The client should return a reference to the new file that has been created for uri, or null to continue with the default implementation.

Parameters:

vfs - a GVfs

identifier - the identifier to look up a GFile for. This can either be a URI or a parse name as returned by g_file_get_parse_name()

Returns:

a GFile for identifier.

Since:

2.50

upcall

default MemorySegment upcall(MemorySegment vfs,
 MemorySegment identifier,
 MemorySegment userData)

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

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, 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
