class Generator |
| |
Abstract representation of an in-memory grammar that generates parsers
The generator class manages a collection of
ElementToken objects. These element token objects
allow the generator to be separated from the
particular parser associated with any particular EBNF
grammar. In fact, it is possible to create entire grammars
using only the generator objects as a python API.

Methods defined here:
- __init__(self)
- Initialise the Generator
- addDefinition(self, name, rootElement)
- Add a new definition (object) to the generator
- addDefinitionSource(self, item)
- Add a source for definitions when the current grammar doesn't supply
a particular rule (effectively common/shared items for the grammar).
- buildParser(self, name, methodSource=None)
- Build the given parser definition, returning a TextTools parsing tuple
- cacheCustomTerminalParser(self, index, flags, parser)
- Optimization to reuse customized terminal parsers
- getCustomTerminalParser(self, index, flags)
- Retrieved a cached customized terminal parser or None
- getNameIndex(self, name)
- Return the index into the main list for the given name
- getNames(self)
- Return the list of root generator objects
- getObjectForName(self, name)
- Determine whether our methodSource has a parsing method for the given name
returns ( flags or 0 , tagobject)
- getParserList(self)
- getRootObject(self, name)
- Get a particular root object by name
- getRootObjects(self)
- Return the list of root generator objects
- getTagObjectForName(self, name)
- Get any explicitly defined tag object for the given name
- getTerminalParser(self, index)
- Try to retrieve a parser from the parser-list
- setTerminalParser(self, index, parser)
- Explicitly set the parser value for given name

Stand-in class supporting operation of SimpleParse 1.0 applications
There was really only the one method of interest, parserbyname,
everything else was internal (and is now part of
simpleparsegrammar.py).

Methods defined here:
- __init__(self, production, prebuilt=())
- parserbyname(self, name)
- Retrieve a tag-table by production name
