Detailed Description

Base class for visitors that traverse a tree in a 2D feature plane.

Holds the shared state for projecting p-dimensional splits into (var_i, var_j) space with the remaining variables fixed: the two display variable indices, fixed variable values, the visible bounding box, and the stack of ancestor half-space constraints.

Implements the common traversal logic in visit(TreeBranch): push the current split as a constraint, recurse into both children (lower then upper), and pop. Subclasses override visit_branch() to do work at each split node (e.g. clip and emit a boundary segment) and visit(TreeLeaf) for leaf-specific work.

Constructor & Destructor Documentation

◆ SpatialVisitor()

ppforest2::viz::SpatialVisitor::SpatialVisitor	(	int	var_i,
		int	var_j,
		std::vector< std::pair< int, types::Feature > > const &	fixed_vars,

		types::Feature	x_max,
		types::Feature	y_min,
		types::Feature	y_max )

Member Function Documentation

◆ visit() [1/2]

void ppforest2::viz::SpatialVisitor::visit ( TreeBranch const & node )

overridevirtual

Push constraint, recurse into children, pop.

Subclasses that need per-node work (e.g. BoundaryVisitor) override this, do their work, then call SpatialVisitor::visit(node) for the traversal.

Reimplemented from ppforest2::TreeNode::Visitor.

◆ visit() [2/2]

void ppforest2::viz::SpatialVisitor::visit ( TreeLeaf const & node )

overridevirtual

No-op default; override in subclasses that need leaf work.

Reimplemented from ppforest2::TreeNode::Visitor.
