Different partitions are distributed dynamically to workers without any specific order. In addition to partition size, the application can specify a closure wrapper for a dynamic partitioner. A closure wrapper allows the application to wrapper a partitioned task (i.e., closure) with a custom function object that performs additional tasks. For example: std::atomic<int>count=0; tf::Taskflowtaskflow; taskflow.for_each_index(0,100,1, [](){ printf("%d\n",i); }, tf::DynamicPartitioner(0,[](auto&&closure){ //dosomethingbeforeinvokingthepartitionedtask //... //invokethepartitionedtask closure(); //dosomethingelseafterinvokingthepartitionedtask //... } ); executor.run(taskflow).wait(); tf::DynamicPartitioner< C > tf::IsPartitioner tf::PartitionerBase< DefaultClosureWrapper > tf::DynamicPartitioner< C > tf::IsPartitioner tf::PartitionerBase< DefaultClosureWrapper > tf::DynamicPartitioner_chunk_size tf::DynamicPartitioner_closure_wrapper tf::DynamicPartitionerchunk_size tf::DynamicPartitionerchunk_size tf::DynamicPartitionerclosure_wrapper tf::DynamicPartitionerclosure_wrapper tf::DynamicPartitionerclosure_wrapper_type tf::DynamicPartitionerDynamicPartitioner tf::DynamicPartitionerDynamicPartitioner tf::DynamicPartitionerDynamicPartitioner tf::DynamicPartitionerloop tf::DynamicPartitionerloop_until tf::DynamicPartitionerPartitionerBase tf::DynamicPartitionerPartitionerBase tf::DynamicPartitionerPartitionerBase tf::DynamicPartitionertype
