/// \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.
