// File: DG.hxx
//
// Contents: Class declarations for the base DataGen tool APIs.
//
// Classes: DG_BASE - Base class for all DataGen classes.
//
// DG_INTEGER - DataGen class to generate random integer types.
//
// DG_REAL - DataGen class to generate random floating point
// number types.
//
// DG_ASCII - DataGen class to generate random ASCII character
// strings.
//
// DG_UNICODE - DataGen class to generate random Unicode
// character strings.
//
// DG_BSTR - DataGen class to generate random BSTR's
//
// DG_STRING - DataGen system independent strings
//
// Functions: None.
//
// History: 11-Mar-92 RonJo Created by breaking off the appropriate
// parts of DataGen.hxx.
//
// 21-Oct-92 RonJo Removed long double reference when
// compiling for Win32/NT because it does
// not support long doubles.
//
// 22-Mar-94 RickTu Added BSTR support for Win32/Cairo.
//
// 12-Apr-96 MikeW Base BSTR off of OLECHAR not WCHAR
//
// 07-Nov-96 BogdanT Added DG_STRING combining DG_ASCII&DG_UNICODE
//
// 11-Nov-97 a-sverrt Added member functions that provide access to
// the hidden members of the private base class
// ( member using-declarations ) to remove the "access
// declarations are deprecated" warning on the Macintosh.
//
// Note: DataGen is not multithread safe. It is not a problem of
// crashing, but instead values used internally to generate
// the next value get changed by subsequent threads before
// the new value is finally calculated. To avoid this, tests
// should either generate the values in the parent thread
// before starting the threads, or generate seed values and
// provide a separate datagen object for each thread. dda

//
// Class: DG_BASE (dgb)
//
// Purpose: Base class for all DataGen classes. Provides constructor,
// and destructor, along with other miscellaneous common member
// functions.
//
// Interface: DG_BASE - Sets the internal seed to the value parameter
// passed, or to a random value if the parameter
// value is 0. Then sets up the internal random
// number tables. All this is done by calling
// SetSeed()
//
// ~DG_BASE - Nothing at this time.
//
// SetSeed - Resets the internal seed to the value parameter
// passed, or to a random value if the parameter
// passed is 0. Then resets the internal random
// number tables based on the internal seed.
//
// GetSeed - Returns the value of the internal seed to the
// caller.
//
// Error - Returns the last setting of the return code by
// the DG_BASE based object, and if available, a
// string containing more information about the
// error. If there is no further information, the
// string pointer will be NULL.
//
// Notes: None.
//
// History: 14-Sep-91 RonJo Created.
//
// 25-Nov-91 RonJo Added prefixed underscores to all
// protected and private members.
//
// 25-Nov-91 RonJo Moved the Error member function from
// the DATAGEN class to here.

// Interface: DG_REAL - Only passes a seed value back to the DG_BASE
// constructor.
//
// Generate - Returns an floating point number of the type
// pointed to by the p@Number parameter, where @ is
// an abbreviation of the prescribed type (e.g. a
// double would be pdblNumber). The range of the
// random point number is bounded if bounds are
// provided otherwise, the bounds are the maximum
// values allowed for the data type.
//
// Notes: The defaults for the minimum and maximum values allow for
// only producing positive numbers. If you give negative
// minimum and/or maximum values, remember that the maximum
// range for that type is then halved.
