| /// @class HostInfo HostInfo.h "lldb/Host/HostInfo.h" |
| /// @brief A class that provides host computer information. |
| /// |
| /// HostInfo is a class that answers information about the host operating |
| /// system. Note that HostInfo is NOT intended to be used to manipulate or |
| /// control the operating system. |
| /// |
| /// HostInfo is implemented in an OS-specific class (for example |
| /// HostInfoWindows) in a separate file, and then typedefed to HostInfo here. |
| /// Users of the class reference it as HostInfo::method(). |
| /// |
| /// Not all hosts provide the same functionality. It is important that methods |
| /// only be implemented at the lowest level at which they make sense. It should |
| /// be up to the clients of the class to ensure that they not attempt to call a |
| /// method which doesn't make sense for a particular platform. For example, |
| /// when implementing a method that only makes sense on a posix-compliant |
| /// system, implement it on HostInfoPosix, and not on HostInfoBase with a |
| /// default implementation. This way, users of HostInfo are required to think |
| /// about the implications of calling a particular method and if used in a |
| /// context where the method doesn't make sense, will generate a compiler error. |
