Interface  Description 

HeapPriorityQueueElement 
Interface for objects that can be managed by a
HeapPriorityQueue . 
InternalKeyContext<K> 
This interface is the current context of a keyed state.

KeyGroupPartitionedPriorityQueue.PartitionQueueSetFactory<T,PQS extends InternalPriorityQueue<T> & HeapPriorityQueueElement> 
Factory that produces the subqueues that represent the partitions of a
KeyGroupPartitionedPriorityQueue . 
LevelIndexHeader 
Head level index for skip list.

Class  Description 

AbstractHeapPriorityQueue<T extends HeapPriorityQueueElement> 
Abstract base class for heap (object array) based implementations of priority queues, with
support for fast deletes via
HeapPriorityQueueElement . 
AbstractHeapState<K,N,SV> 
Base class for partitioned
State implementations that are backed by a regular heap hash
map. 
CopyOnWriteSkipListStateMap<K,N,S> 
Implementation of state map which is based on skip list with copyonwrite support.

CopyOnWriteSkipListStateMapSnapshot<K,N,S> 
This class represents the snapshot of a
CopyOnWriteSkipListStateMap . 
CopyOnWriteStateMap<K,N,S> 
Implementation of Flink's inmemory state maps with copyonwrite support.

CopyOnWriteStateMap.StateMapEntry<K,N,S> 
One entry in the
CopyOnWriteStateMap . 
CopyOnWriteStateMapSnapshot<K,N,S> 
This class represents the snapshot of a
CopyOnWriteStateMap . 
CopyOnWriteStateTable<K,N,S> 
This implementation of
StateTable uses CopyOnWriteStateMap . 
CopyOnWriteStateTableSnapshot<K,N,S> 
This class represents the snapshot of a
CopyOnWriteStateTable and has a role in operator
state checkpointing. 
HeapKeyedStateBackend<K> 
A
AbstractKeyedStateBackend that keeps state on the Java Heap and will serialize state to
streams provided by a CheckpointStreamFactory upon checkpointing. 
HeapKeyedStateBackendBuilder<K> 
Builder class for
HeapKeyedStateBackend which handles all necessary initializations and
clean ups. 
HeapPriorityQueue<T extends HeapPriorityQueueElement> 
Basic heapbased priority queue for
HeapPriorityQueueElement objects. 
HeapPriorityQueueSet<T extends HeapPriorityQueueElement> 
A heapbased priority queue with set semantics, based on
HeapPriorityQueue . 
HeapPriorityQueueSetFactory 
Factory for
HeapPriorityQueueSet . 
HeapPriorityQueueSnapshotRestoreWrapper<T extends HeapPriorityQueueElement> 
This wrapper combines a HeapPriorityQueue with backend meta data.

HeapPriorityQueueStateSnapshot<T> 
This class represents the snapshot of an
HeapPriorityQueueSet . 
HeapRestoreOperation<K> 
Implementation of heap restore operation.

InternalKeyContextImpl<K> 
The default
InternalKeyContext implementation. 
KeyGroupPartitionedPriorityQueue<T,PQ extends InternalPriorityQueue<T> & HeapPriorityQueueElement> 
This implementation of
InternalPriorityQueue is internally partitioned into subqueues
per keygroup and essentially works as a heapofheaps. 
NestedMapsStateTable<K,N,S> 
This implementation of
StateTable uses NestedStateMap . 
NestedStateMap<K,N,S>  
NestedStateMapSnapshot<K,N,S> 
This class represents the snapshot of a
NestedStateMap . 
OnHeapLevelIndexHeader 
Implementation of
LevelIndexHeader which stores index on heap. 
SkipListUtils 
Utilities for skip list.

StateMap<K,N,S> 
Base class for state maps.

StateMapSnapshot<K,N,S,T extends StateMap<K,N,S>> 
Base class for snapshots of a
StateMap . 
StateTable<K,N,S> 
Base class for state tables.

Enum  Description 

NodeStatus 
Status of the node.
