Class Description

 Roo1DTable implements a one-dimensional table. A table is the category
 equivalent of a plot. To create a table use the RooDataSet::table method.

Roo1DTable(const char *name, const char *title, const RooAbsCategory& cat) : RooTable(name,title), _total(0), _nOverflow(0)

 Create an empty table from abstract category. The number of table entries and
 their names are taken from the category state labels at the time of construction,
 but not reference to the category is retained after the construction phase.
 Use fill() to fill the table.

Roo1DTable(const Roo1DTable& other) : RooTable(other), _total(other._total), _nOverflow(other._nOverflow)

 Copy constructor

~Roo1DTable()

 Destructor

void fill(RooAbsCategory& cat, Double_t weight)

 Increment the counter of the table slot with
 the name corresponding to that of the current
 category state. If the current category state
 matches no table slot name, the table overflow
 counter is incremented.

void printToStream(ostream& os, PrintOption opt, TString indent) const

 Print the formateed table contents on the given stream

Double_t get(const char* label, Bool_t silent) const

 Return the table entry named 'label'. Zero is returned
 if given label doesn't occur in table.

Double_t getOverflow() const

 Return the number of overflow entries in the table.

Double_t getFrac(const char* label, Bool_t silent) const

 Return the fraction of entries in the table contained in the slot named 'label'.
 The normalization includes the number of overflows.
 Zero is returned if given label doesn't occur in table.
