lookup method

  1. @override
V? lookup(
  1. String key,
  2. V value
)
inherited

If TTMultiMap contains specified (key, value) pair then return stored value.

Returned value may not be the same as value if element type equality does not include identity.

If key is mapped to multiple elements satisfying equality to value then only the first will be returned

If (key, value) pair is not present then returns null.

Throws ArgumentError if key is empty or null.

Implementation

@override
V? lookup(String key, V value) =>
    _root?.getKeyNode(_mapKey(key))?.lookupValue(value);
