Detailed Description

template<int grainSize = 0>
class CnC::tag_partitioner< grainSize >

Use this instead of default_partitioner if your tag is self-dividing (e.g. a range) and you want to use the partitioning mechanism through cnC::tag_collection::put_range

Member Typedef Documentation

typedef range_is_tag_type split_type

set to range_is_tag_type if tag is self-dividing, e.g. if the range-type is also the tag-type as passed to the step set to range_is_range_type if tag is undivisible, e.g. if range-type != step_type

Reimplemented from default_partitioner< grainSize >.

Member Function Documentation

bool divide_and_originate	(	Range &	range,
		StepInstance &	si
	)		const [inline]

divide given range into in arbitrary number of ranges of type Range

Call si.originate_range( r ) for each new range. The original - but modified - range must *not* be passed to originate_range! If tag-types are self-dividing (e.g. if range-type == tag-type) you should call "originate" instead of "originate_range" for leaves of the recursive range-tree.

Returns:

true if the orignal - but modified - range needs further splitting, false if no further splitting is desired.

The aggregated set of the members of the sub-ranges applied to "t.originate[_range]" must equal the set of member in given range. Overlapping ranges or gaps may lead to arbitrary effects.

Parameters:

range	the original range to split, may be altered
si	opaque object, call t.originate[_range]( r ) for all split-off sub-ranges

Reimplemented from default_partitioner< grainSize >.
