Method Detail

getContext

public String getContext(int ID)
Description copied from interface: LRTranslatorGrammar
Returns the name of the context having the given ID or null if no such ID is known.
Specified by:
getContext in interface LRTranslatorGrammar

getContextAction

public int getContextAction(int cID,
                            int tID)
Description copied from interface: LRTranslatorGrammar
Returns the action defined for the given grammar symbol in the given context as one of the ACTION_XXX constants in this interface. If the contextID or symbolID is not known, UNDEFINED_CONTEXT or UNDEFINED_SYMBOL will be returned. Note: If UNDEFINED_SYMBOL is returned the ID may still be a valid terminal or nonterminal, but it not a member of the given context.
Specified by:
getContextAction in interface LRTranslatorGrammar

getContextRegister

public int getContextRegister(int cID,
                              int tID)
Description copied from interface: LRTranslatorGrammar
Returns an integer stored at the value of the given contextID and symbolID. This is used in conjunction with getContextAction(int, int) such that the second member in the tuple (action, register) is returned. If the contextID or symbolID is not known, UNDEFINED_CONTEXT or UNDEFINED_SYMBOL will be returned.
Specified by:
getContextRegister in interface LRTranslatorGrammar

getContextTerminals

Returns the ID of the goal symbol (a nonterminal) or UNDEFINED_NONTERMINAL is no such goal symbol has been set.
Specified by:
getGoalNonTerminal in interface LRTranslatorGrammar

getName

public String getName()
Description copied from interface: TranslatorGrammar
Returns the name of the Translator.
