Method Details

leaveNode

public void leaveNode(CAstNode n,
 CAstVisitor.Context c,
 CAstVisitor<CAstVisitor.Context> visitor)

Description copied from class: CAstVisitor

Leave any node. Override only this to change behavior for all nodes.

Overrides:

leaveNode in class CAstVisitor<CAstVisitor.Context>

Parameters:

n - the node to process

c - a visitor-specific context

findAll

public Collection<CAstPattern.Segments> findAll(CAstVisitor.Context c,
 CAstNode top)

doVisit

protected boolean doVisit(CAstNode n,
 CAstVisitor.Context context,
 CAstVisitor<CAstVisitor.Context> visitor)

Description copied from class: CAstVisitor

Node processing hook; sub-classes are expected to override if they introduce new node types.

(Should invoke super.doVisit() for unprocessed nodes.)

Overrides:

doVisit in class CAstVisitor<CAstVisitor.Context>

Returns:

true if node was handled

doVisitAssignNodes

protected boolean doVisitAssignNodes(CAstNode n,
 CAstVisitor.Context context,
 CAstNode v,
 CAstNode a,
 CAstVisitor<CAstVisitor.Context> visitor)

Description copied from class: CAstVisitor

Node processing hook; sub-classes are expected to override if they introduce new node types that appear on the left hand side of assignment operations.

(Should invoke super.doVisit() for unprocessed nodes.)

Overrides:

doVisitAssignNodes in class CAstVisitor<CAstVisitor.Context>

Returns:

true if node was handled
