Synopsis

#include <antlr3input.h>

Data Fields

ANTLR3_INT32 charPositionInLine
The offset within the current line of the current character.
void * currentLine
Pointer into the input buffer where the current line started.
ANTLR3_UINT32 line
The line number we are traversing in the input file.
void * nextChar
Pointer to the next character to be consumed from the input data This is cast to point at the encoding of the original file that was read by the functions installed as pointer in this input stream context instance at file/string/whatever load time.
