Class: VirtualBox::Host

Inherits:
AbstractModel show all
Defined in:
lib/virtualbox/host.rb

Overview

Represents information about the host machine. This includes information such as memory available, processors, dvds, network interfaces, etc.

This information is different from system properties in that some parts represent data which is stored in the VirtualBox “registry” (such as the dvd drives, host only network interfaces, etc.)

Constructor Details

#initialize(caller, raw) ⇒ Host

Initializes the system properties object. This shouldn’t be called directly. Instead ‘Global#system_properties` should be used to retrieve this object.

Dynamic Method Handling

This class handles dynamic methods through the method_missing method in the class VirtualBox::AbstractModel::Dirty

Class Method Details

.populate_relationship(caller, data) ⇒ SystemProperties

Populates the system properties relationship for anything which is related to it.

**This method typically won’t be used except internally.**

Returns:
