Method Details

run

DBusInterfaceVTable run(DBusConnection connection,
 String sender,
 String objectPath,
 String interfaceName,
 String node,
 MemorySegment outUserData)

The type of the dispatch function in GDBusSubtreeVTable.

Subtrees are flat. node, if non-null, is always exactly one segment of the object path (ie: it never contains a slash).

Parameters:

connection - A GDBusConnection.

sender - The unique bus name of the remote caller.

objectPath - The object path that was registered with g_dbus_connection_register_subtree().

interfaceName - The D-Bus interface name that the method call or property access is for.

node - A node that is a child of objectPath (relative to objectPath) or null for the root of the subtree.

outUserData - Return location for user data to pass to functions in the returned GDBusInterfaceVTable.

Returns:

A GDBusInterfaceVTable or null if you don't want to handle the methods.

Since:

2.26

upcall

default MemorySegment upcall(MemorySegment connection,
 MemorySegment sender,
 MemorySegment objectPath,
 MemorySegment interfaceName,
 MemorySegment node,
 MemorySegment outUserData,
 MemorySegment userData)

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

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment, MemorySegment, 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
