Overrides org.antlr.v4.runtime.Lexer.getCharPositionInLine.

Implements org.antlr.v4.runtime.TokenSource.getCharPositionInLine.

Doc from org.antlr.v4.runtime.TokenSource.getCharPositionInLine.

Get the index into the current line for the current position in the input stream. The first character on a line has position 0.

Returns:int

The line number for the current position in the input stream, or -1 if the current token source does not track character positions.
