# SplayTreeMap<K, V>.fromIterable constructor

SplayTreeMap<K, V>.fromIterable(Iterable iterable, { K key(dynamic element), V value(dynamic element), int compare(K key1, K key2), bool isValidKey(dynamic potentialKey) })

Creates a SplayTreeMap where the keys and values are computed from the `iterable`.

For each element of the `iterable` this constructor computes a key/value pair, by applying `key` and `value` respectively.

The keys of the key/value pairs do not need to be unique. The last occurrence of a key will simply overwrite any previous value.

If no functions are specified for `key` and `value` the default is to use the iterable value itself.

## Implementation

    factory SplayTreeMap.fromIterable(Iterable iterable,
        {K key(element),
        V value(element),
        int compare(K key1, K key2),
        bool isValidKey(potentialKey)}) {
      SplayTreeMap<K, V> map = SplayTreeMap<K, V>(compare, isValidKey);
      MapBase._fillMapWithMappedIterable(map, iterable, key, value);
      return map;
    }
