Field Summary

Fields

Modifier and Type	Field	Description
StarLoopbackState	loopBackState
BitSet	precedenceLoopbackStates	For precedence decisions, this set marks states S which have all of the following characteristics: One or more invocation sites of the current rule returns to S. The closure from S includes the current decision without passing through any rule invocations or stepping out of the current rule.
boolean	precedenceRuleDecision	Indicates whether this state can benefit from a precedence DFA during SLL decision making.

Field Details

loopBackState

public StarLoopbackState loopBackState

precedenceRuleDecision

public boolean precedenceRuleDecision

Indicates whether this state can benefit from a precedence DFA during SLL decision making.

This is a computed property that is calculated during ATN deserialization and stored for use in ParserATNSimulator and ParserInterpreter.

precedenceLoopbackStates

public BitSet precedenceLoopbackStates

For precedence decisions, this set marks states S which have all of the following characteristics:

• One or more invocation sites of the current rule returns to S.
• The closure from S includes the current decision without passing through any rule invocations or stepping out of the current rule.

This field is null when precedenceRuleDecision is false.
