org.antlr.grammar.v3.ActionAnalysis
- All Implemented Interfaces:
- TokenSource
public class ActionAnalysis
- extends Lexer
We need to set Rule.referencedPredefinedRuleAttributes before
code generation. This filter looks at an action in context of
its rule and outer alternative number and figures out which
rules have predefined prefs referenced. I need this so I can
remove unusued labels. This also tracks, for labeled rules,
which are referenced by actions.

analyze
public void analyze()
getGrammarFileName
public java.lang.String getGrammarFileName()
- Description copied from class:
BaseRecognizer
- For debugging and other purposes, might want the grammar name.
Have ANTLR generate an implementation for this method.
- Overrides:
getGrammarFileName
in class BaseRecognizer
nextToken
public Token nextToken()
- Description copied from class:
Lexer
- Return a token from this source; i.e., match a token on the char
stream.
- Specified by:
nextToken
in interface TokenSource
- Overrides:
nextToken
in class Lexer
memoize
public void memoize(IntStream input,
int ruleIndex,
int ruleStartIndex)
- Description copied from class:
BaseRecognizer
- Record whether or not this rule parsed the input at this position
successfully. Use a standard java hashtable for now.
- Overrides:
memoize
in class BaseRecognizer
alreadyParsedRule
public boolean alreadyParsedRule(IntStream input,
int ruleIndex)
- Description copied from class:
BaseRecognizer
- Has this rule already parsed input at the current index in the
input stream? Return the stop token index or MEMO_RULE_UNKNOWN.
If we attempted but failed to parse properly before, return
MEMO_RULE_FAILED.
This method has a side-effect: if we have seen this input for
this rule and successfully parsed before, then seek ahead to
1 past the stop token matched for this rule last time.
- Overrides:
alreadyParsedRule
in class BaseRecognizer
