SplayTreeMap<K, V> constructor

SplayTreeMap<K, V>([
  1. int compare(
    1. K key1,
    2. K key2
    )?,
  2. bool isValidKey(
    1. dynamic potentialKey
    )?
])

Implementation

SplayTreeMap(
    [int Function(K key1, K key2)? compare,
    bool Function(dynamic potentialKey)? isValidKey])
    : _compare = compare ?? _defaultCompare<K>(),
      _validKey = isValidKey ?? ((dynamic a) => a is K);
