Detailed Description

See the Qt Concurrent module documentation for an overview of available functions, or see below for detailed information on each function.

class FutureResult

This enum type is used to invoke a special overload of spawn (QtConcurrent::FutureResult) that doesn’t return a future object.

Constant	Description
QtConcurrent.FutureResult.Ignore	An auxiliary tag which introduced to improve code readability.

class ThreadFunctionResult

class ReduceOption

(inherits enum.Flag) This enum specifies the order of which results from the map or filter function are passed to the reduce function.

Constant	Description
QtConcurrent.UnorderedReduce	Reduction is done in an arbitrary order.
QtConcurrent.OrderedReduce	Reduction is done in the order of the original sequence.
QtConcurrent.SequentialReduce	Reduction is done sequentially: only one thread will enter the reduce function at a time. (Parallel reduction might be supported in a future version of Qt Concurrent.)
