Constructor & Destructor Documentation

Parser::Parser (  const string &  configFile, Grammar *  pGrammar = NULL )

Here is the call graph for this function:

Parser::~Parser (   )  [virtual]

Here is the call graph for this function:

Parser::Parser (   )  [inline, protected]

Member Function Documentation

void Parser::clear (   )  [virtual]

Clears the parser's state. Note that this does not include the grammar. Clears the parser by clearing the contents of its components. The components are still there, not being deleted. The grammar is not cleared.

Here is the call graph for this function:

Grammar * Parser::getGrammar (   )  const [virtual]

vector< pair< BilexMTree *, SCORE > > Parser::getParse (   )  [virtual]

This overloaded version reparses the currently initialized SentenceTuple. This could be useful if, e.g., the grammar is updated.

Here is the call graph for this function:

vector< pair< BilexMTree *, SCORE > > Parser::getParse (  SentenceTuple &   )  [virtual]

compute the parse and return the resulting tree

Here is the call graph for this function:

void Parser::initialize (  SentenceTuple &   )  [protected, virtual]

Initializes the parser for new input.

Here is the call graph for this function:

bool Parser::multiPassParse (   )  [protected, virtual]

Parse, using multiple passes if necessary until the parsing goal is found. Note that if the multiPassParse in the constructor is false, then it is just ordinary parsing. Use the goal.trace() to see which sub-goal is achieved or whether the parsing fails. Whenever the agenda is empty, the parser restarts!!!

Here is the call graph for this function:

bool Parser::onePassParse (   )  [protected, virtual]

One pass parsing until the goal is reached or the parsing fails. Use goal.trace() to see which sub-goal is achieved or whether the parsing fails. Whenever the agenda is empty, the parser restarts!!!

Here is the call graph for this function:

void Parser::parse (   )  [inline, private]

This method kept private to avoid use/redefinition.

void Parser::setGrammar (  Grammar *  pGrammar  )  [virtual]

Set the model for the parser.

Here is the call graph for this function:

bool Parser::silentParse (  SentenceTuple &   )  [virtual]

Attempt to achieve the parsing goal but do not compute or return the tree.

Here is the call graph for this function:

Member Data Documentation

bool Parser::m_multiPassParse [protected]

if true, then we use multi-pass parsing

Agenda* Parser::m_pAgenda [protected]

The reference to the Agenda.

ParseStats Parser::m_parseStats [protected]

Grammar* Parser::m_pGrammar [protected]

The reference to the grammar.

Logic* Parser::m_pLogic [protected]

The reference to the Logic.
