Member Function Documentation

boundingRect()

QRectF frechet::data::IntervalPair::boundingRect ( ) const

inline

calculate the bounding rectangle, i.e. a rectangle that is defined by the horizontal and vertical intervals

Returns

the bounding rectangle

Definition at line 480 of file interval.h.

clear()

IntervalPair& frechet::data::IntervalPair::clear ( )

inline

clear both intervals (assigning NAN as boundary values)

Returns

this interval pair, now invalid

Definition at line 518 of file interval.h.

operator!=()

bool frechet::data::IntervalPair::operator!= ( const IntervalPair &  that )

inline

non-equality comparator

Parameters

that	another pair of intervals

Returns

true, if bouth pairs are not equal

Definition at line 499 of file interval.h.

operator+=()

IntervalPair& frechet::data::IntervalPair::operator+= ( const IntervalPair &  that )

inline

union operator

Parameters

that	another pair of intervals

Returns

this interval pair, containing the union of both interval pairs

Definition at line 507 of file interval.h.

operator==()

bool frechet::data::IntervalPair::operator== ( const IntervalPair &  that )

inline

equality comparator

Parameters

that	another pair of intervals

Returns

true, if bouth pairs are equal

Definition at line 491 of file interval.h.

translated()

IntervalPair frechet::data::IntervalPair::translated ( double  i, double  j  ) const

inline

translate both intervals

Parameters

i	horizontal offset
j	vertical offset

Returns

a copy of this object, shifted by offsets
