Here is the call graph for this function:

reset()

static void UTAP::PositionTracker::reset ( )

static

Resets position tracker to position 0.

setPath()

void UTAP::PositionTracker::setPath ( UTAP::ParserBuilder *  parser, std::string  s  )

static

Sets the current path to s, offset to 0 and line to 1.

Sets the position of builder to [position, position + 1) (a one character dummy position; this is useful when assigning error messages to XML elements without a text content). Adds position to builder and increments it by 1.
