TSFleStack
class TSFleStack
.
====================================================================== Class TSFleStack - Hold iteration-values for expand/reduce This class is used to save values if expand/reduce enters an embeded or a virtual token. So no restriction about 'size' is given. This class also holds a counter, which is filled with the values from the connected token-definition and which can be modified independently. This includes a reload with a new value. The state of this class describes the NEXT item, which is required from input and must be processed. Such an item may also be a new 'embedded token'. If it was found, the state of this class can be 'advanced' to the next type-definition of the current token (or to EOT). ##TSFleStack (Eyecatcher) ======================================================================

protected TSFleStack()
===================================================================== Constructor: (1) Create Default-Entry =====================================================================
protected TSFleStack(TSFleTok cT)
===================================================================== Constructor: (2) Create Standard-Entry =====================================================================
protected TSFleStack(TSFleTok cT, int cP)
===================================================================== Constructor: (3) Create Special Loop-Entry ('Virtual Token') This method is used to create a 'virtual token'-definition which is used to realize repeatable groups of items. Such a token can neither be a 'comment' nor be followed by a LF. =====================================================================
Method Detail |
---|
protected final boolean advDef()
===================================================================== Method "advDef" Advance to next type-definition and set new values. Method returns 'true', if EOT (End-Of-Token) is (already) reached. ##advDef.TSFleStack (Eyecatcher) =====================================================================
protected final boolean chkAdv(boolean skp)
===================================================================== Method "chkAdv" Check if advance to next type-definition should be done. Method returns 'true', if 'advDef' could be tried. However, this is also returned if EOT (End-Of-Token) is already reached. If 'skp' is set(true), type-definition may be advanced to next one even if 'until-end'-attribute is active or the (valid) counter is NOT expired. Attention: If method returns 'true', the internal counter may not be modified. ##chkAdv.TSFleStack (Eyecatcher) =====================================================================
protected final boolean chkFlg2()
===================================================================== Method "chkFlg2" Examine current Flag-Definition (do not change) and return state. Meaning: 'Switch to NL before type-definition is used' Attention: Method is used if the flag MUST NOT be reset within first argument. ##chkFlg2.TSFleStack (Eyecatcher) =====================================================================
protected final boolean chkFlg3()
===================================================================== Method "chkFlg3" Examine current Flag-Definition (do not change) and return state. Meaning: 'Switch to NL before advance to next type' Attention: Method is used if the flag MUST NOT be reset within first argument. ##chkFlg3.TSFleStack (Eyecatcher) =====================================================================
protected final boolean chkFlg4()
===================================================================== Method "chkFlg4" Examine current Flag-Definition (do not change) and return state. Meaning: 'Option depends on type of entry' Attention: Method is used if the flag MUST NOT be reset within first argument. ##chkFlg4.TSFleStack (Eyecatcher) =====================================================================
protected final boolean chkOpt(int cP)
===================================================================== Method "chkOpt" Check current type-definion if it is an optional one. Method returns 'true' if the current type-definition is an optional one but the preconditions are NOT met, so that it cannot be used. If all preconditions are met, the 'optional'-attribute is reset and 'false' is returned. If method returns 'false' the current type-definition should be used. Else it should be skipped. Attention: If 'cP==0' a special request is scheduled, which returns the current state of the 'Opt'-flag. ##chkOpt.TSFleStack (Eyecatcher) =====================================================================
protected final int chkPos(int cP)
===================================================================== Method "chkPos" Check current position relative to provided value. If '0' is used as the argument, the original, unmodified value is returned. ##chkPos.TSFleStack (Eyecatcher) =====================================================================
protected final boolean clrFlg1(int mv)
===================================================================== Method "clrFlg1" Process 'repeat-counter' if current Flag-Definition request this. Reset flag and return previous state. Meaning: 'Multiply repeat-value with group-counter' ##clrFlg1.TSFleStack (Eyecatcher) =====================================================================
protected final boolean clrFlg2()
===================================================================== Method "clrFlg2" Clear current Flag-Definition and return PREVIOUS state. Meaning: 'Switch to NL before type-definition is used' ##clrFlg2.TSFleStack (Eyecatcher) =====================================================================
protected final boolean clrFlg4()
===================================================================== Method "clrFlg4" Clear current Flag-Definition and return PREVIOUS state. This is the common version with NO special actions and used with either 'Expand' or 'Reduce'. Meaning: 'Option depends on type of entry' ##clrFlg4.TSFleStack (Eyecatcher) =====================================================================
protected final java.lang.String clrFlg4_EE(int cP, int mx)
===================================================================== Method "clrFlg4_EE" (Version: Type14-Expand) Clear current Flag-Definition and return number of items. Add aditional actions needed for type-definition. Meaning: 'Option depends on type of entry' ##clrFlg4_EE.TSFleStack (Eyecatcher) =====================================================================
protected final boolean clrFlg4_RE(int rc)
===================================================================== Method "clrFlg4_RE" (Version: Type14-Reduce) Clear current Flag-Definition and return PREVIOUS state. Add aditional actions needed for type-definition. Meaning: 'Option depends on type of entry' ##clrFlg4_RE.TSFleStack (Eyecatcher) =====================================================================
protected final int getCmd(boolean cmd)
===================================================================== Method "getCmd" Resolve current item-type. Attention: If 'cmd' is NOT set, the whole type-definition is returned (if possible). (used for debugging purposes) ##getCmd.TSFleStack (Eyecatcher) =====================================================================
protected final int getCnt()
===================================================================== Method "getCnt" Return current value of alternate counter. ##getCnt.TSFleStack (Eyecatcher) =====================================================================
protected final int getRep(int cP)
===================================================================== Method "getRep" Return number of items of same type to be resolved from buffer. Reset internal counter to '0'. If 'until-end'-function is active, number is computed as distance to EOT. ##getRep.TSFleStack (Eyecatcher) =====================================================================
protected final java.lang.String isEOT()
===================================================================== Method "isEOT" Check if token is completely processed. Return current type-definiton if it is NOT. ##isEOT.TSFleStack (Eyecatcher) =====================================================================
protected final boolean isOpt()
===================================================================== Method "isOpt" Check current type-definion if it is (as per definition) an optional one. Attention: The 'Optional'-attribute may be modified due to external conditions. So, the original attribute-setting is again extracted and returned. ##isOpt.TSFleStack (Eyecatcher) =====================================================================
protected final boolean runCnt(boolean inc)
===================================================================== Method "runCnt" Handle alternate counter. Increment / decrement it, and test if it terminates. ##runCnt.TSFleStack (Eyecatcher) =====================================================================
protected final boolean setLF(boolean nS)
===================================================================== Method "setLF" Set new value of current 'Linefeed'-Status and return previous one. ##setLF.TSFleStack (Eyecatcher) =====================================================================
protected final int setPos(int nV)
===================================================================== Method "setPos" Set new value of input-position and return previous one. ##setPos.TSFleStack (Eyecatcher) =====================================================================
protected final java.lang.String toStr()
===================================================================== Method "toStr" Build an String-representation of all values of this class ##toStr.TSFleStack (Eyecatcher) =====================================================================
