Entity<Key extends EntityKey> class

Represents an entity with a unique identifier and timestamp.

This is a base class for all entities in the system. Each entity has:

Type parameter Key must extend EntityKey.

Entity({String? id, int? timeMills, Key? key}): Creates an entity with optional id, timeMills, and key
const

equals(Object? e1, Object? e2) → bool: Compare two elements for being equal.
inherited
hash(Object? o) → int: Creates a combined hash code for a number of objects.
inherited
isInsertable(String key, dynamic value) → bool: Checks if a field is insertable (valid key and non-null value)
isValidKey(Object? o) → bool: Test whether an object is a valid argument to equals and hash.
inherited
iterableEquals<T>(Iterable<T> a, Iterable<T> b, {bool unordered = false, bool equals(T a, T b)?}) → bool
makeKey() → Key: Constructs the key for the entity.
modify<T extends Object>(Modifier<T>? current, T? old) → T?
noSuchMethod(Invocation invocation) → dynamic: Invoked when a nonexistent method or property is accessed.
inherited
notEquals(dynamic e1, dynamic e2) → bool: Compare two elements for being not equal.
inherited
toString() → String: A string representation of this object.
