class THaVar: public TNamed

 Copy constructor

 Assignment operator. Must be explicit due to limitations of CINT.

 Destructor

 Compare the size of this variable to that of 'rhs'.
 Scalars always agree. Arrays agree if either they are of the same fixed
 size, or their count variables are identical, or they belong to the
 same object array.

 Return pointer to length of object array.
 Result must be copied or used immediately.

 Retrieve variable from a ROOT object, either via a function call
 or from a TSeqCollection

 Return linear index into this array variable corresponding
 to the array element described by 'elem'.
 Return -1 if subscript(s) out of bound(s) or -2 if incompatible arrays.

 Return linear index into this array variable corresponding
 to the array element described by the string 's'.
 's' must be either a single integer subscript (for a 1-d array)
 or a comma-separated list of subscripts (for multi-dimensional arrays).

 NOTE: This method is vastly less efficient than
 THaVar::Index( THaArraySring& ) above because the string has
 to be parsed first.

 Return -1 if subscript(s) out of bound(s) or -2 if incompatible arrays.

Print a description of this variable

 Set the name of the variable

 Set name and description of the variable

  if( ( fValueP == NULL ) ||
    ( fType>=kDoubleP  && *fDoubleDD == NULL ) ||
    ( fType>=kDouble2P && (*fDouble3D)[i] == NULL ))
  return 0.0;

 The following are necessary to initialize empty THaVars such as those in arrays,
 where each element was constructed with the default constructor
