virtual bool Fiber::FragmentSelector::contains

(

CreativeArrayBase &

CAB

)

[pure virtual]

Coarse evaluation: Check if this field may fullfill the selection criteria as entity.

May for instance check interfaces or attributes on the given fragment, like the min/max range.

Parameters:

CAB

A container that holds array attributes, and may eventually create data as well.

virtual void Fiber::FragmentSelector::createIndices	(	std::vector< unsigned int > &	Indices,
		const MemCore::RefPtr< MemBase > &	Data
	)			[pure virtual]

Fine evaluation: compute indices that match.

Parameters:

	Indices,:	An empty array of indices, which will be filled by indices of the current data set which match the criteria that is implemented in this Selector.
	Data,:	The actual values.
