LocalThread<T> constructor
LocalThread<T> ()
A Dart equivalent of Java's ThreadLocal
, scoped to the current Isolate.
ThreadLocal<T>
provides isolate-local storage for values that are only
visible within the currently running Isolate. This is useful when you
want to maintain separate values across isolates, such as request-scoped
data in a concurrent server.
Internally, each isolate maintains its own value store via a LocalThreadStorageBucket, so values set in one isolate will not affect others.
Example
final threadLocal = ThreadLocal<int>();
// In isolate A
threadLocal.set(42);
print(threadLocal.get()); // prints: 42
// In isolate B (separate execution context)
print(threadLocal.get()); // prints: null
This API abstracts away the complexity of isolate-specific data management by allowing you to interact with values as if they were thread-local, even though Dart uses isolates instead of OS threads.
Implementation
LocalThread() : _key = LocalThreadKey.generate();
