size

expect open override val size: Int(source)

Returns the size of the collection.

If a collection contains more than Int.MAX_VALUE elements, the value of this property is unspecified. For implementations allowing to have more than Int.MAX_VALUE elements, it is recommended to explicitly document behavior of this property.
