EnvParser class
Constructors
- EnvParser(TokenStream input)
Properties
- ATNWithBypassAlts → ATN
-
The ATN with bypass alternatives is expensive to create so we create it
lazily.
no setterinherited
- buildParseTree ↔ bool

Specifies whether or not the parser should construct a parse tree during
the parsing process. The default value is
true
.getter/setter pairinherited - bypassAltsAtnCache ↔ ATN?
-
This field maps from the serialized ATN string to the deserialized
ATN
with bypass alternatives.getter/setter pairinherited - context ↔ ParserRuleContext?
-
The
ParserRuleContext
object for the currently executing rule. This is always non-null during the parsing process.getter/setter pairinherited - currentToken → Token
-
Match needs to return the current input symbol, which gets put
into the label for the associated token ref; e.g., x=ID.
no setterinherited

String pattern, int patternRuleIndex, [Lexer? lexer]) → ParseTreePattern -
The preferred method of getting a tree pattern. For example, here's a
sample use:
inherited
-
consume(
) → Token -
Consume and return the {@linkplain #getCurrentToken current symbol}.
inherited
-
createErrorNode(
ParserRuleContext parent, Token t) → ErrorNode -
How to create an error node, given a token, associated with a parent.
Typically, the error node to create is not a function of the parent.
inherited
-
createTerminalNode(
ParserRuleContext parent, Token t) → TerminalNode -
How to create a token leaf node associated with a parent.
Typically, the terminal node to create is not a function of the parent.

ParserRuleContext localctx, int state, int ruleIndex, int precedence) → void -
inherited
-
enterRule(
ParserRuleContext localctx, int state, int ruleIndex) → void -
Always called by generated parsers upon entry to a rule. Access field
{@link #_ctx} get the current context.

inherited
-
getRuleInvocationStack(
[RuleContext? p]) → List< String> -
Return List<String> of the rule names in your parser instance
leading up to a call to the current rule. You could override if
you want more details such as the file/line info of where
in the ATN a rule is invoked.

-

-

Checks whether or not
symbol
can follow the current state in the ATN. The behavior of this method is equivalent to the following, but is implemented such that the complete context-sensitive follow set does not need to be explicitly constructed.inherited -

is registered as a parse listener for the parser.inherited -

. If the symbol type matches, {@link ANTLRErrorStrategy#reportMatch} and {@link #consume} are called to complete the match process.inherited -
matchWildcard(

(i.e. has a value greater than 0), {@link ANTLRErrorStrategy#reportMatch}
