Constructors
Limit
Limit(
SizeT value,
bool hardLimit = false,
bool isLowerLimit = false
);
Creates the Limit.
Value contains the upper row hint, if hardLimit is set to true, the limit acts as a hard border, ie. every query must return exactly value rows, returning more than value objects will throw an exception! LowerLimits always act as hard-limits!
A value of LIMIT_UNLIMITED disables the limit.
Destructor
~Limit
~Limit();
Destroys the Limit.
Member Functions
isHardLimit 
bool isHardLimit() const;
Returns true if the limit is a hard limit.
isLowerLimit

Returns true if the limit is a lower limit, otherwise it is an upperLimit
operator !=
bool operator != (
const Limit & other
) const;
Inequality operator.
operator ==
bool operator == (
const Limit & other
) const;
Equality operator.
value
SizeT value() const;
Returns the value of the limit
