public Class AcceptStateInfo

extends Object
Class Inheritance
Imports
org.antlr.v4.runtime.atn.LexerActionExecutor, .ParserATNSimulator
Stores information about a DFAState which is an accept state under some condition. Certain settings, such as ParserATNSimulator#getPredictionMode(), may be used in addition to this information to determine whether or not a particular state is an accept state.

public LexerActionExecutor getLexerActionExecutor()

Gets the LexerActionExecutor which can be used to execute actions and/or commands after the lexer matches a token.

getPredictionback to summary
public int getPrediction()

Gets the prediction made by this accept state. Note that this value assumes the predicates, if any, in the DFAState evaluate to true. If predicate evaluation is enabled, the final prediction of the accept state will be determined by the result of predicate evaluation.
