Detailed Description

A "generic" user-controlled ViewEdge iterator. This iterator is in particular built from a unary predicate and a binary predicate. First, the unary predicate is evaluated for all potential next ViewEdges in order to only keep the ones respecting a certain constraint. Then, the binary predicate is evaluated on the current ViewEdge together with each ViewEdge of the previous selection. The first ViewEdge respecting both the unary predicate and the binary predicate is kept as the next one. If none of the potential next ViewEdge respects these 2 predicates, 0 is returned.

Constructor & Destructor Documentation

◆ ChainPredicateIterator() [1/3]

Freestyle::ChainPredicateIterator::ChainPredicateIterator	(	bool	iRestrictToSelection = `true`,
		bool	iRestrictToUnvisited = `true`,
		ViewEdge *	begin = `NULL`,
		bool	orientation = `true`
	)

inline

Builds a ChainPredicateIterator from a starting ViewEdge and its orientation.

Parameters

iRestrictToSelection	Indicates whether to force the chaining to stay within the set of selected ViewEdges or not.
iRestrictToUnvisited	Indicates whether a ViewEdge that has already been chained must be ignored ot not.
begin	The ViewEdge from where to start the iteration.
orientation	If true, we'll look for the next ViewEdge among the ViewEdges that surround the ending ViewVertex of begin. If false, we'll search over the ViewEdges surrounding the ending ViewVertex of begin.

◆ ChainPredicateIterator() [2/3]

Freestyle::ChainPredicateIterator::ChainPredicateIterator	(	UnaryPredicate1D &	upred,
		BinaryPredicate1D &	bpred,
		bool	iRestrictToSelection = `true`,
		bool	iRestrictToUnvisited = `true`,
		ViewEdge *	begin = `NULL`,
		bool	orientation = `true`
	)

inline

Builds a ChainPredicateIterator from a unary predicate, a binary predicate, a starting ViewEdge and its orientation.

Parameters

iRestrictToSelection	Indicates whether to force the chaining to stay within the set of selected ViewEdges or not.
iRestrictToUnvisited	Indicates whether a ViewEdge that has already been chained must be ignored ot not.
upred	The unary predicate that the next ViewEdge must satisfy.
bpred	The binary predicate that the next ViewEdge must satisfy together with the actual pointed ViewEdge.
begin	The ViewEdge from where to start the iteration.
orientation	If true, we'll look for the next ViewEdge among the ViewEdges that surround the ending ViewVertex of begin. If false, we'll search over the ViewEdges surrounding the ending ViewVertex of begin.

Returns the string "ChainPredicateIterator"

Reimplemented from Freestyle::ChainingIterator.

Definition at line 399 of file ChainingIterators.h.

◆ init()

virtual int Freestyle::ChainPredicateIterator::init ( )
