ITreeAdaptorRulePostProcessing Method |
Given the root of the subtree created for this rule, post process
it to do any simplifications or whatever you want. A required
behavior is to convert ^(nil singleSubtree) to singleSubtree
as the setting of start/stop indexes relies on a single non-nil root
for non-flat trees.

Return Value
Type: Object[Missing <returns> documentation for "M:Stimulsoft.Data.Expressions.Antlr.Runtime.Tree.ITreeAdaptor.RulePostProcessing(System.Object)"]
Remarks
Flat trees such as for lists like "idlist : ID+ ;" are left alone
unless there is only one ID. For a list, the start/stop indexes
are set in the nil node.
This method is executed after all rule tree construction and right
before setTokenBoundaries().
