class HExpString: public TObject

_HADES_CLASS_DESCRIPTION

 This is a helper class which keeps the expression in the form of a string
 and all the related information necessary for evaluation, like for example
 parameters indexes. It is also used by the subpanels for local and
 global conditions, since it contains the helper functions for
 the interactive definition of an expression by means of GUI.

Function documentation

void makeExp()
 This function updates the string according to the indexes of
 the string elements which are stored in array "index".
void addItem(Int_t idx)
 This function adds a new index to the array of element indexes and
 class makeExp() to update the string.
void addString(const Char_t* strng)
 This function scans the string and divides it into subelements
 the indexes of which will be stored in the arrays "index" and "paridx".
 This function is mainly used by the GUI.
void undo()
 This function deletes the index of the last element from the array "index".
 All spaces are skipped.
void updateList(TGListBox* p)
 This function puts the content of the string to the list box p.
void copy(HExpString& hes)
 This function makes a copy of this object and stores it in the new
 object "hes".
void check()
 This function checks the validity of the mathematical expression.
void checkParam()
 This function checks the validity of the expression when it serves
 for definition of a new parameter.
HExpString()
{cursor=parcur=-1; kClear=kTRUE; kValid = kFALSE; }
virtual ~HExpString()
{}
void clear()
{ cursor = parcur = -1; makeExp(); }
Bool_t isClear()
{ return kClear; }
Bool_t isValid()
{ return kValid; }
const Char_t* getExp()
{ return exp; }
