nextsolidtoken

public TSourceToken nextsolidtoken(TSourceToken ptoken,
                                   int pstep,
                                   boolean pcmtissolidtoken)

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.

Returns:

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.

pcmtissolidtoken - If it's true then treat comment as solid token.

Returns:

nextObjectNameToken

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.

solidtokenafterpos

public int solidtokenafterpos(int pStart,
                              int pTokenCode,
                              int pSteps,
                              String pIgnoreThisString)

Search token by token code, start from pStart within range pSteps, and ignore pIngoreThisString if any during searching. Ingore non-solid token while searching.

Parameters:

pStart - Start from this position.

pTokenCode - TokenCode that search for.

pSteps - Must > 0.

pIgnoreThisString - String to be ignored.

Returns:

0 if no token found, otherwise, return position in sourcetoken list.

solidtokenbefore

public TSourceToken solidtokenbefore(int pStart)

Search solid token before pStart.

Parameters:

pStart -

Returns:

return null if no token found.

sqlplusaftercurtoken

public boolean sqlplusaftercurtoken()

returnaftercurtoken

public boolean returnaftercurtoken(boolean ignorecmt)

Is there linebreak after current token.

Parameters:

ignorecmt - If it's true, ignore comment while searching linebreak.

Returns:

returnbeforecurtoken

public boolean returnbeforecurtoken(boolean ignorecomment)

Is there a linebreak before current token, comment is not ignored if ignorecomment is true, space is ignored.

Returns:

searchToken

public TSourceToken searchToken(int targetTokenCode,
                                String targetTokenText,
                                TSourceToken startToken,
                                int range)

Parameters:

targetTokenCode, - >0, search target token by token code; = 0, search target token by token text

targetTokenText -

startToken -

range, - > 0, search token after startToken = 0, just compare with this startToken, < 0, search token before startToken

Returns:

setTokenStatus

public void setTokenStatus(ETokenStatus ps,
                           int pstart,
                           int pend)
