Uses of RefCounted in org.apache.cassandra.io.sstable.format

Classes in org.apache.cassandra.io.sstable.format that implement RefCounted

Modifier and Type	Class and Description
class	SSTableReader An SSTableReader can be constructed in a number of places, but typically is either read from disk at startup, or constructed from a flushed memtable, or after compaction to replace some existing sstables.

Uses of RefCounted in org.apache.cassandra.io.sstable.format.big

Classes in org.apache.cassandra.io.sstable.format.big that implement RefCounted

Modifier and Type	Class and Description
class	BigTableReader SSTableReaders are open()ed by Keyspace.onStart; after that they are created by SSTableWriter.renameAndOpen.

Subinterfaces of RefCounted in org.apache.cassandra.utils.concurrent

Modifier and Type	Interface and Description
interface	SelfRefCounted<T extends SelfRefCounted<T>>

Classes in org.apache.cassandra.utils.concurrent that implement RefCounted

Modifier and Type

Class and Description

class

Ref<T> An object that needs ref counting does the two following: - defines a Tidy object that will cleanup once it's gone, (this must retain no references to the object we're tracking (only its resources and how to clean up)) Then, one of two options: 1) Construct a Ref directly pointing to it, and always use this Ref; or 2) - implements RefCounted - encapsulates a Ref, we'll call selfRef, to which it proxies all calls to RefCounted behaviours - users must ensure no references to the selfRef leak, or are retained outside of a method scope.
