  • Field Details

    • curpos

      public int curpos
      Used by parser internally. this curpos is start from -1, when a new token is created, curpos must be increased by 1 and then assign this value to the TSourceToken.posinlist .

      Find solid token start from ptoken, distance is pstep.
      Parameters:
      ptoken - Search start from this token.
      pstep - If pstep > 0 then find solid token after ptoken, if pstep < 0 then find solid token before ptoken.
      pcmtissolidtoken - If it's true then treat comment as solid token.

    • nextsolidtoken

      public TSourceToken nextsolidtoken(int ptokenpos, int pstep, boolean pcmtissolidtoken)
      Find solid token start from ptoken, distance is pstep.
      Parameters:
      ptokenpos - Search start from this position, not include this token
      pstep - If pstep > 0 then find solid token after ptoken, if pstep < 0 then find solid token before ptoken.

      public int nextObjectNameToken(int ptokenpos, int pstep, boolean pcmtissolidtoken)
      Search token of the next/previous object
      Parameters:
      ptokenpos - , search from this token, not included.
      pstep - pstep > 0 means search forward, <0 means search backward
      pcmtissolidtoken - , treat comment as solid token if it's true.
      Returns:
      -1 means not found. If search next, then return position of the last token of qualified object name, if search previous, then return position of the first token of qualified object name.
