/// @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.
|
|
