Much is now generally used with uncountable nouns. The equivalent used with countable nouns is many. In positive contexts, much is widely avoided: I have a lot of money instead of I have much money. There are some exceptions to this, however: I have much hope for the future. A lot of these cases are emotive transitive verbs and nouns. I have much need for a new assistant. In parallel, I need ...
An asynchronous operation (created via std::async, std::packaged_task, or std::promise) can provide a std::future object to the creator of that asynchronous operation. The creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the std::future.
The code above might look ugly, but all you have to understand is that the FutureBuilder widget takes two arguments: future and builder, future is just the future you want to use, while builder is a function that takes two parameters and returns a widget. FutureBuilder will run this function before and after the future completes.
C++ includes built-in support for threads, atomic operations, mutual exclusion, condition variables, and futures.
The class template std::packaged_task wraps any Callable target (function, lambda expression, bind expression, or another function object) so that it can be invoked asynchronously. Its return value or exception thrown is stored in a shared state which can be accessed through std::future objects.
If the future is the result of a call to std::async that used lazy evaluation, this function returns immediately without waiting. This function may block for longer than timeout_duration due to scheduling or resource contention delays. The standard recommends that a steady clock is used to measure the duration.
future (const future &) = delete; ~future (); future & operator =(const future &) = delete; future & operator =(future &&) noexcept; shared_futurewait_until waits for a result to become available. It blocks until specified timeout_time has been reached or the result becomes available, whichever comes first. The return value indicates why wait_until returned. If the future is the result of a call to async that used lazy evaluation, this function returns immediately without waiting. The behavior is undefined if valid () is false before ...
The scoped enumeration std::future_errc defines the error codes reported by std::future and related classes in std::future_error exception objects. Only four error codes are required, although the implementation may define additional error codes.
The class template std::future provides a mechanism to access the result of asynchronous operations: An asynchronous operation (created via std::async, std::packaged_task, or std::promise) can provide a std::future object to the creator of that asynchronous operation. The creator of the asynchronous operation can then use a variety of methods to query, wait for, or extract a value from the std ...
The function template std::async runs the function f asynchronously (potentially in a separate thread which might be a part of a thread pool) and returns a std::future that will eventually hold the result of that function call.
Population Statistics & Trends Fawn to doe ratios and yearling buck percentages are used to help estimate the deer herd size annually and is the starting point for setting antlerless harvest quotas.
Harvest trends are provided and summarized by Deer Management Unit (DMU). Harvest within each DMU is tracked by the type of harvest (antlered vs antlerless), land type (public vs private), and by weapon type.
The primary objective of Long Term Trend (LTT) Lakes monitoring is to document long-term trends in lake water chemistry. This data set also provides context for water chemistry in other lakes in terms of intra and inter-annual variability.
Investigate trends in groundwater levels. Seepage lakes have no surface inlets or outlets, so lake levels are determined by precipitation, evaporation, and groundwater levels. Investigate relationships between lake level and other variables, such as water clarity, water quality, aquatic plants, and fish.
Eurasian watermilfoil: long-term trends in unmanaged populations The Wisconsin Department of Natural Resources conducts and supports a variety of projects that improve our understanding of aquatic invasive species (AIS) and the ways we manage them.
