List of unowned() Examples

Examples of unowned()

org.grouplens.lenskit.collections.LongKeyDomain.unowned()
Mark this key set as unowned. The next call to {@link #clone()} will mark thekey set as owned and return it rather than making a copy. This allows code to avoid an extra copy when creating a key set to pass off to another method or object that will make a defensive copy.
You almost certainly do not want to call this method.
Any object or method that receives a key set that it intends to take ownership of must call {@link #clone()} to make sure that it owns the set. @return This key set (for chaining).
