Detailed Description

The set of fields needed by an abstract recognizer to recognize input
and recover from errors etc...  As a separate state object, it can be
shared among multiple grammars; e.g., when one grammar imports another.

These fields are publically visible but the actual state pointer per
parser is protected.

rve_interface_gen::antlr3::recognizers.RecognizerSharedState::text

You can set the text for the current token to override what is in the input char buffer.

Use setText() or can set this instance var.

rve_interface_gen::antlr3::recognizers.RecognizerSharedState::token

The goal of all lexer rules/methods is to create a token object.

This is an instance variable as multiple rules may collaborate to create a single token. nextToken will return this object after matching lexer rule(s). If you subclass to allow multiple token emissions, then set this to the last token to be matched or something nonnull so that the auto token emit mechanism will not emit another token.

rve_interface_gen::antlr3::recognizers.RecognizerSharedState::tokenStartCharIndex

What character index in the stream did the current token start at? Needed, for example, to get the text for current token.

Set at the start of nextToken.

rve_interface_gen::antlr3::recognizers.RecognizerSharedState::tokenStartCharPositionInLine

The character position of first character within the line.

Definition at line 71 of file recognizers.py.

rve_interface_gen::antlr3::recognizers.RecognizerSharedState::tokenStartLine

The line on which the first character of the token resides.
