Constructor details

◆ HandList() [1/2]

Leap::HandList::HandList ( const ListBaseImplementation< Hand > & )

◆ HandList() [2/2]

LEAP_EXPORT Leap::HandList::HandList ( )

Constructs an empty list of hands.

Function details

◆ append()

LEAP_EXPORT HandList& Leap::HandList::append ( const HandList & other )

Appends the members of the specified HandList to this HandList.

Parameters

other A HandList object containing Hand objects to append to the end of this HandList.

◆ begin()

LEAP_EXPORT const_iterator Leap::HandList::begin ( ) const

The C++ iterator set to the beginning of this HandList.

◆ count()

LEAP_EXPORT int Leap::HandList::count ( ) const

Returns the number of hands in this list.

Returns: The number of hands in this list.

◆ empty()

LEAP_EXPORT bool Leap::HandList::empty ( ) const

Deprecated. Use HandList::isEmpty() instead.

See also: HandList::isEmpty()

◆ end()

LEAP_EXPORT const_iterator Leap::HandList::end ( ) const

The C++ iterator set to the end of this HandList.

◆ frontmost()

LEAP_EXPORT Hand Leap::HandList::frontmost ( ) const

The member of the list that is farthest to the front within the standard Leap frame of reference (i.e has the smallest Z coordinate).

Returns: The frontmost hand, or invalid if list is empty.

◆ isEmpty()

LEAP_EXPORT bool Leap::HandList::isEmpty ( ) const

Reports whether the list is empty.

Returns: True, if the list has no members.

◆ leftmost()

LEAP_EXPORT Hand Leap::HandList::leftmost ( ) const

The member of the list that is farthest to the left within the standard Leap frame of reference (i.e has the smallest X coordinate).

Returns: The leftmost hand, or invalid if list is empty.

◆ operator[]()

LEAP_EXPORT Hand Leap::HandList::operator[] ( int index ) const

Access a list member by its position in the list.
