方法详细资料

checkConflicts

public void checkConflicts()

checkForRuleArgumentAndReturnValueConflicts

protected void checkForRuleArgumentAndReturnValueConflicts(Rule r)

checkForRuleDefinitionProblems

protected void checkForRuleDefinitionProblems(Rule r)

lookForReferencesToUndefinedSymbols

protected void lookForReferencesToUndefinedSymbols()

If ref to undefined rule, give error at first occurrence. Give error if you cannot find the scope override on a rule reference. If you ref ID in a combined grammar and don't define ID as a lexer rule it is an error.

checkForGlobalScopeTokenConflict

protected void checkForGlobalScopeTokenConflict(AttributeScope scope)

checkForRuleScopeAttributeConflict

public void checkForRuleScopeAttributeConflict(Rule r,
                                               Attribute attribute)

Check for collision of a rule-scope dynamic attribute with: arg, return value, rule name itself. Labels are checked elsewhere.

checkForLabelConflict

protected void checkForLabelConflict(Rule r,
                                     Token label)

Make sure a label doesn't conflict with another symbol. Labels must not conflict with: rules, tokens, scope names, return values, parameters, and rule-scope dynamic attributes defined in surrounding rule.

checkForLabelTypeMismatch

public boolean checkForLabelTypeMismatch(Rule r,
                                         Token label,
                                         int type)

If type of previous label differs from new label's type, that's an error.
