Methods

overloadedMethod :: MethodProxy RegionIterGetSubregionMethodInfo RegionIter -> signature -> s

regionIterGetSubregion

Arguments

:: (HasCallStack, MonadIO m)

=> RegionIter

iter: a RegionIter.

-> m (Bool, TextIter, TextIter)

Returns: True if start and end have been set successfully (if non-Nothing), or False if iter is the end iterator or if the region is empty.

Gets the subregion at this iterator.
