Method Summary

Modifier and Type	Method	Description
Variant	run(DBusConnection connection, @Nullable String sender, String objectPath, String interfaceName, String propertyName, GError[] error)	The type of the getProperty function in GDBusInterfaceVTable.
default MemorySegment	toCallback(Arena arena)	Creates a native function pointer to the upcall(MemorySegment, MemorySegment, MemorySegment, MemorySegment, MemorySegment, MemorySegment, MemorySegment) method.
default MemorySegment	upcall(MemorySegment connection, MemorySegment sender, MemorySegment objectPath, MemorySegment interfaceName, MemorySegment propertyName, MemorySegment error, MemorySegment userData)	The upcall method is called from native code.

Method Details

run

Variant run(DBusConnection connection,
 @Nullable String sender,
 String objectPath,
 String interfaceName,
 String propertyName,
 GError[] error)

The type of the getProperty function in GDBusInterfaceVTable.

Parameters:

connection - A GDBusConnection.

sender - The unique bus name of the remote caller or null if not specified by the caller, e.g. on peer-to-peer connections.

objectPath - The object path that the method was invoked on.

interfaceName - The D-Bus interface name for the property.

propertyName - The name of the property to get the value of.

error - Return location for error.

Returns:

A GVariant with the value for propertyName or null if error is set. If the returned GVariant is floating, it is consumed - otherwise its reference count is decreased by one.

Since:

2.26

upcall

default MemorySegment upcall(MemorySegment connection,
 MemorySegment sender,
 MemorySegment objectPath,
 MemorySegment interfaceName,
 MemorySegment propertyName,
 MemorySegment error,
 MemorySegment userData)

The upcall method is called from native code. The parameters are marshaled and run(DBusConnection, String, String, String, String, GError[]) 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
