Public Static Attributes

static bool log_pattern_set_by_user

Flag to indicate if the log pattern was set by the user.

static bool log_level_set_by_user

Flag to indicate if the log level was set by the user.

This is used to set the default log level (INFO) in Application::Application() if the user has not set the log level explicitly before Application::Application() is called and no environment variable (HOLOSCAN_LOG_LEVEL) is set.
