handle_is_supported_provider

Description:

public virtual signal bool handle_is_supported_provider (DBusMethodInvocation invocation, string arg_provider_type)

Signal emitted when a remote caller is invoking the IsSupportedProvider D-Bus method.

If a signal handler returns true, it means the signal handler will handle the invocation (e.g. take a reference to invocation and eventually call complete_is_supported_provider or e.g. return_error on it) and no other signal handlers will run. If no signal handler handles the invocation, the UNKNOWN_METHOD error is returned.

Parameters:

invocation	A DBusMethodInvocation.
arg_provider_type	Argument passed by remote caller.

Returns:

DBUS_METHOD_INVOCATION_HANDLED or true if the invocation was handled, DBUS_METHOD_INVOCATION_UNHANDLED or false to let other signal handlers run.
