Class ImmutableKeyValuePairs<K,​V>

  • Type Parameters:
    V - The type of the values contained in this.
    Direct Known Subclasses:
    Labels.ArrayBackedLabels
    @Immutable
public abstract class ImmutableKeyValuePairs<K,​V>
extends java.lang.Object
    An immutable set of key-value pairs.

    Key-value pairs are dropped for null or empty keys.

    Note: for subclasses of this, null keys will be removed, but if your key has another concept of being "empty", you'll need to remove them before calling sortAndFilter(Object[], boolean), assuming you don't want the "empty" keys to be kept in your collection.
