AutoCloseableInstanceTracker

abstract class AutoCloseableInstanceTracker<T>(val unbindOnClose: Boolean = UNBIND_ON_CLOSE_DEFAULT, setCreator: () -> MutableSet<T>? = null) : InstanceTracker<T> , AutoCloseable

InstanceTracker which also implements the AutoCloseable interface.

This implementation is best suited for InstanceTracker which also requires the use of coroutines. Note that unbind must be invoked manually before close if unbindOnClose is set to false (which is the default).

Parameters

unbindOnClose

Whether to invoke unbind automatically when close is invoked. This requires less manual coding resource management, at the expense that deadlocks may occur.

setCreator

Creator for the Set used to track instances.
