DelegatedReadonlySignal<T> class

A read-only signal that shares a source with reference counting.

When disposed, decrements the reference count. The source is automatically disposed when all delegated signals are disposed.

Parameters:

• delegated: The reference-counted helper managing the source

Example:

final helper = DelegatedRefCountHelper<ReadonlySignal<int>>(source);
final delegated = DelegatedReadonlySignal(helper);
print(delegated.value); // Accesses shared source

Implemented types

• ReadonlySignal<T>

Available extensions

• JoltUtilsReadableExtension
• JoltUtilsStreamExtension
• JoltUtilsUntilExtension
