Detailed Description

@brief Baseclass for generated tree parsers.

A parser for a stream of tree nodes.  "tree grammars" result in a subclass
of this.  All the error reporting and recovery is shared with Parser via
the BaseRecognizer superclass.

Member Function Documentation

def rve_interface_gen.antlr3.tree.TreeParser._getAncestor	(		adaptor,
			tokenNames,
			t,
			goal
	)		[static, private]

Helper for static inContext.

Definition at line 2278 of file tree.py.

def rve_interface_gen.antlr3.tree.TreeParser._inContext	(		cls,
			adaptor,
			tokenNames,
			t,
			context
	)		[private]

The worker for inContext.

It's static and full of parameters for testing purposes.

def rve_interface_gen.antlr3.tree.TreeParser.getCurrentInputSymbol	(		self,
			input
	)

Definition at line 2195 of file tree.py.

def rve_interface_gen.antlr3.tree.TreeParser.getErrorHeader	(		self,
			e
	)

Prefix error message with the grammar name because message is
always intended for the programmer because the parser built
the input tree not the user.

Definition at line 2330 of file tree.py.

def rve_interface_gen.antlr3.tree.TreeParser.getErrorMessage	(		self,
			e,
			tokenNames
	)

Tree parsers parse nodes they usually have a token object as
payload. Set the exception token and do the default behavior.

def rve_interface_gen.antlr3.tree.TreeParser.inContext	(		self,
			context,
			adaptor = None,
			tokenName = None,
			t = None
	)

Check if current node in input has a context.

Context means sequence of nodes towards root of tree.  For example,
you might say context is "MULT" which means my parent must be MULT.
"CLASS VARDEF" says current node must be child of a VARDEF and whose
parent is a CLASS node.  You can use "..." to mean zero-or-more nodes.
"METHOD ... VARDEF" means my parent is VARDEF and somewhere above
that is a METHOD node.  The first node in the context is not
necessarily the root.  The context matcher stops matching and returns
true when it runs out of context.  There is no way to force the first
node to be the root. 

Definition at line 2210 of file tree.py.

def rve_interface_gen.antlr3.tree.TreeParser.matchAny	(		self,
			ignore
	)

Match '.' in tree parser has special meaning.  Skip node or
entire tree if node has children.  If children, scan until
corresponding UP node.

Definition at line 2289 of file tree.py.

def rve_interface_gen.antlr3.tree.TreeParser.mismatch	(		self,
			input,
			ttype,
			follow
	)

We have DOWN/UP nodes in the stream that have no line info; override.
plus we want to alter the exception type. Don't try to recover
from tree parser errors inline...
