Class NvtxUniqueRange

java.lang.Object
ai.rapids.cudf.NvtxUniqueRange
All Implemented Interfaces:
AutoCloseable
public class NvtxUniqueRange extends Object implements AutoCloseable
This class supports start/end NVTX profiling ranges. Start/end: The constructor instantiates a new NVTX range and keeps a unique handle that comes back from the NVTX api (nvtxRangeId). The handle is used to later close such a range. This type of range does not have the same order-of-operation requirements that the push/pop ranges have: the `NvtxUniqueRange` instance can be passed to other scopes, and even to other threads for the eventual call to close. It can be used in the same try-with-resources way as push/pop, or interleaved with other ranges, like so: 
   NvtxUniqueRange a = new NvtxUniqueRange("a", NvtxColor.RED);
   NvtxUniqueRange b = new NvtxUniqueRange("b", NvtxColor.BLUE);
   a.close();
   b.close();
