Abstract strategy for variable selection.

Writes ctx.var_selection.

Member Function Documentation

compute()

virtual void ppforest2::vars::VariableSelection::compute ( NodeContext & ctx, stats::RNG & rng ) const

protectedpure virtual

Subclass implementation of variable selection.

Implemented in ppforest2::vars::All, and ppforest2::vars::Uniform.

select()

void ppforest2::vars::VariableSelection::select	(	NodeContext &	ctx,
		stats::RNG &	rng ) const

Select a subset of variables and store the result in the context.

Public NVI entry point: skips if ctx.aborted is set, otherwise delegates to the subclass-provided compute.
