public final int size()

See QSet::size()const

Specified by:

Returns:

the number of elements in this container

public boolean equals(Object other)

See QSet::operator==(QSet<T>)const

Specified by:

equals in interface Collection<T>

Specified by:

Overrides:

equals in class QtObject

Parameters:

other - other object

Returns:

add

@QtUninvokable
public final boolean add(T e)

Adds the specified element to this set if it is not already present (optional operation). More formally, adds the specified element e to this set if the set contains no element e2 such that Objects.equals(e, e2). If this set already contains the element, the call leaves the set unchanged and returns false.
