The "transform" step transforms an AST node 61577f75a7498e9e2536434da0ef0da0eea390d18bDouglas Gregor/// or the parts of an AST node using the various transformation functions, 62577f75a7498e9e2536434da0ef0da0eea390d18bDouglas Gregor/// then passes the pieces on to the "rebuild" step, which constructs a new AST 63577f75a7498e9e2536434da0ef0da0eea390d18bDouglas Gregor/// node of the appropriate kind from the pieces. The default transformation 64577f75a7498e9e2536434da0ef0da0eea390d18bDouglas Gregor/// routines recursively transform the operands to composite AST nodes (e.g., 65577f75a7498e9e2536434da0ef0da0eea390d18bDouglas Gregor/// the pointee type of a PointerType node) and, if any of those operand nodes 66577f75a7498e9e2536434da0ef0da0eea390d18bDouglas Gregor/// were changed by the transformation, invokes the rebuild operation to create 67577f75a7498e9e2536434da0ef0da0eea390d18bDouglas Gregor/// a new AST node. 68577f75a7498e9e2536434da0ef0da0eea390d18bDouglas Gregor/// 691eb4433ac451dc16f4133a88af2d002ac26c58efMike Stump/// Subclasses can customize the transformation at various levels.
