Method Summary

Modifier and Type	Method	Description
Type	run(DBusObjectManagerClient manager, String objectPath, @Nullable String interfaceName, @Nullable MemorySegment data)	Function signature for a function used to determine the GType to use for an interface proxy (if interfaceName is not null) or object proxy (if interfaceName is null).
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment, MemorySegment) method.
default long	upcall(MemorySegment manager, MemorySegment objectPath, MemorySegment interfaceName, MemorySegment data)	The upcall method is called from native code.

Method Details

run

Type run(DBusObjectManagerClient manager,
 String objectPath,
 @Nullable String interfaceName,
 @Nullable MemorySegment data)

Function signature for a function used to determine the GType to use for an interface proxy (if interfaceName is not null) or object proxy (if interfaceName is null).

This function is called in the thread-default main context (see MainContext#pushThreadDefault) that manager was constructed in.

Parameters:

manager - A GDBusObjectManagerClient.

objectPath - The object path of the remote object.

interfaceName - The interface name of the remote object or null if a GDBusObjectProxy GType is requested.

data - data passed in by the user.

Returns:

A GType to use for the remote object. The returned type must be a GDBusProxy or GDBusObjectProxy -derived type.

Since:

2.30

upcall

default long upcall(MemorySegment manager,
 MemorySegment objectPath,
 MemorySegment interfaceName,
 MemorySegment data)

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

toCallback

default MemorySegment toCallback(Arena arena)

Creates a native function pointer to the upcall(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
