C# Class Microsoft.R.Editor.Validation.TreeValidator

Main R validator: performs syntax check, produces results that then sent to the task list and tagger that creates squiggles. Works asynchronously except the final part that pushes actual task items to the IDE. Additional validators can be added via MEF exports. Validator listens to tree updated events and schedules validation passes for next idle slot. Next idle validation thread starts and performas its work. Validator also listens to changes in settings which may turn validation on or off.

Method	Description
AdviseToIdle ( ) : void
ClearResultsForNode ( IAstNode node ) : void
OnIdle ( object sender, EventArgs e ) : void
OnNodesRemoved ( object sender, TreeNodesRemovedEventArgs e ) : void	Listens to 'nodes removed' event which fires when user deletes text that generated AST nodes or pastes over new content. This allows validator to remove related errors from the task list quickly so they don't linger until the next validation pass.
