Detailed Description

@brief A TreeAdaptor that works with any Tree implementation.

Member Function Documentation

def google.appengine._internal.antlr3.tree.BaseTreeAdaptor.addChild (   self,
  tree,
  child 
)
Add a child to the tree t.  If child is a flat tree (a list), make all
in list children of t.  Warning: if t has no children, but child does
and child isNil then you can decide it is ok to move children to t via
t.children = child.children; i.e., without copying the array.  Just
make sure that this is consistent with have the user will build
ASTs.
def google.appengine._internal.antlr3.tree.BaseTreeAdaptor.becomeRoot (   self,
  newRoot,
  oldRoot 
)
If oldRoot is a nil root, just copy or move the children to newRoot.
If not a nil root, make oldRoot a child of newRoot.

  old=^(nil a b c), new=r yields ^(r a b c)
  old=^(a b c), new=r yields ^(r ^(a b c))

If newRoot is a nil-rooted single child tree, use the single
child as the new root node.

  old=^(nil a b c), new=^(nil r) yields ^(r a b c)
  old=^(a b c), new=^(nil r) yields ^(r ^(a b c))

If oldRoot was null, it's ok, just return newRoot (even if isNil).

  old=null, new=r yields r
  old=null, new=^(nil r) yields ^(nil r)

Return newRoot.  Throw an exception if newRoot is not a
simple node or nil root with a single child node--it must be a root
node.  If newRoot is ^(nil x) return x as newRoot.

Be advised that it's ok for newRoot to point at oldRoot's
children; i.e., you don't have to copy the list.  We are
constructing these nodes so we should have this control for
efficiency.
def google.appengine._internal.antlr3.tree.BaseTreeAdaptor.createToken (   self,
  fromToken = None,
  tokenType = None,
  text = None 
)
Tell me how to create a token for use with imaginary token nodes.
For example, there is probably no input symbol associated with imaginary
token DECL, but you need to create it as a payload or whatever for
the DECL node as in ^(DECL type ID).

If you care what the token payload objects' type is, you should
override this method and any other createToken variant.
def google.appengine._internal.antlr3.tree.BaseTreeAdaptor.dupTree (   self,
  t,
  parent = None 
)
This is generic in the sense that it will work with any kind of
tree (not just Tree interface).  It invokes the adaptor routines
not the tree node routines to do the construction.
def google.appengine._internal.antlr3.tree.BaseTreeAdaptor.errorNode (   self,
  input,
  start,
  stop,
  exc 
)
create tree node that holds the start and stop tokens associated
with an error.

If you specify your own kind of tree nodes, you will likely have to
override this method. CommonTree returns Token.INVALID_TOKEN_TYPE
if no token payload but you might have to set token type for diff
node type.
def google.appengine._internal.antlr3.tree.BaseTreeAdaptor.rulePostProcessing (   self,
  root 
)
Transform ^(nil x) to x and nil to null
