Public methods
acquireReference
open fun acquireReference(): Unit
Acquires a reference to the object.
| Exceptions |
java.lang.IllegalStateException |
if the last reference to the object has already been released. |
close
open fun close(): Unit
Releases a reference to the object, closing the object if the last reference was released. Calling this method is equivalent to calling releaseReference.
| Exceptions |
java.lang.Exception |
if this resource cannot be closed |
java.io.IOException |
if an I/O error occurs |
releaseReference
open fun releaseReference(): Unit
Releases a reference to the object, closing the object if the last reference was released.
releaseReferenceFromContainer
open fun releaseReferenceFromContainer(): Unit
Deprecated: Do not use.
Releases a reference to the object that was owned by the container of the object, closing the object if the last reference was released.
Protected methods
onAllReferencesReleased
protected abstract fun onAllReferencesReleased(): Unit
Called when the last reference to the object was released by a call to releaseReference() or #close().
onAllReferencesReleasedFromContainer
protected open fun onAllReferencesReleasedFromContainer(): Unit
Deprecated: Do not use.
Called when the last reference to the object was released by a call to releaseReferenceFromContainer().
