operator!=()

constexpr bool luciad::TouchPoint::operator!= ( const TouchPoint &  rhs ) const

inlineconstexpr

Inequality comparison operator.

Two touch points are not equal if either their id, state or location differ.

Parameters

rhs	The TouchPoint that this instance is being compared to.

Returns

true if the touch points are not equal.

operator==()

constexpr bool luciad::TouchPoint::operator== ( const TouchPoint &  rhs ) const

inlineconstexpr

Equality comparison operator.

Two touch points are equal if their id, state and location are the same.

Parameters

rhs	The TouchPoint that this instance is being compared to.

Returns

true if the touch points are equal.
