Constructor Details
- LoopStarTable
  
  public LoopStarTable(String colName, double start, double end, double step, Boolean isInteger)
  
  Constructs a loop table from values like the initialisers of a for loop. The isInteger parameter may be set True for an integer column, False for a Double column, and null if the type is to be determined from the input values (integer if all are integers). Integer columns are 32-bit if the values permit, otherwise 64-bit.
  
  Parameters:
  
  colName - name of the single column name in the table
  
  start - initial (row 0) value of variable
  
  end - value which variable will not exceed
  
  step - per-row increment of variable
Method Details
- getRowCount
  
  public long getRowCount()
  
  Description copied from class: ColumnStarTable
  
  Gets the number of rows in the table (which must be applicable to all the columns). Since this is a RandomStarTable the return value must be non-negative.
