Member Function Documentation

virtual void GrammarBase::append (  TerminalValue    value )  [pure virtual]

Append one terminal symbol to the root rule of the grammar. Parameters: value  Appended terminal symbol. This method is used for appending one terminal symbol to the root rule of the grammar. Implemented in KYGrammar. Referenced by XmlSimpleModel::manageEvent, and XmlAdaptiveModel::manageEvent.

virtual void GrammarBase::flush (  void    )  [pure virtual]

Ensure that all appended terminal symbols have been processed. See also: append() Appending a terminal symbol by append() doesn't necessarily mean that this symbol will be immediately processed. Depending on its implementation, the grammar sometimes can (for whatever reason) wait for larger number of terminal symbols. Call to flush() ensures that all appended symbols are processed. Implemented in KYGrammar.

virtual void GrammarBase::print (  void    )  [pure virtual]

Print contents of the grammar. This method outputs a human-readable representation of the grammar on the standard output. Implemented in KYGrammar.

virtual void GrammarBase::reconstructInput (  void    )  [pure virtual]

Reconstruct data represented by the grammar. Call to this method results in reconstruction of the data represented by the grammar. Implemented in KYGrammar.

virtual void GrammarBase::setAlphabetBaseSize (  size_t    size )  [pure virtual]

Set the base size of terminal alphabet. Parameters: size  Size of the alphabet. Call this method if you want to override a default size (256) of the terminal alphabet. Implemented in KYGrammar. Referenced by XmlSimpleModel::manageEvent, and XmlAdaptiveModel::manageEvent.
