Method Details

run

String[] run(DBusConnection connection,
 String sender,
 String objectPath)

The type of the enumerate function in GDBusSubtreeVTable.

This function is called when generating introspection data and also when preparing to dispatch incoming messages in the event that the DBusSubtreeFlags.DISPATCH_TO_UNENUMERATED_NODES flag is not specified (ie: to verify that the object path is valid).

Hierarchies are not supported; the items that you return should not contain the / character.

The return value will be freed with g_strfreev().

upcall

default MemorySegment upcall(MemorySegment connection,
 MemorySegment sender,
 MemorySegment objectPath,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(org.gnome.gio.DBusConnection, java.lang.String, java.lang.String) is executed.

toCallback

default MemorySegment toCallback(Arena arena)

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