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	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.
class	SSTableReaderWithFilter

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

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

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

Modifier and Type	Class	Description
class	BtiTableReader	Reader of SSTable files in BTI format (see BtiFormat), written by BtiTableWriter.

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

Classes in org.apache.cassandra.utils.concurrent with type parameters of type RefCounted

Modifier and Type	Class	Description
class	Refs<T extends RefCounted<T>>	A collection of managed Ref references to RefCounted objects, and the objects they are referencing.

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

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

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

Modifier and Type	Class	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.
static class	Ref.DirectBufferRef<T extends sun.nio.ch.DirectBuffer>	A version of Ref for objects that implement DirectBuffer.

Methods in org.apache.cassandra.utils.concurrent with type parameters of type RefCounted

Modifier and Type	Method	Description
static <T extends RefCounted<T>> Refs<T>	Refs.ref(java.lang.Iterable<? extends T> reference)
static <T extends RefCounted<T>> Refs<T>	Refs.tryRef(java.lang.Iterable<? extends T> reference)	Acquire a reference to all of the provided objects, or none
