| /// \class HostInfo HostInfo.h "lldb/Host/HostInfo.h" |
| /// 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. |
