Interface Summary

Interface	Description
CloseableIterable<E>	Interface that provides semantics of a Iterable and AutoCloseable interfaces.
CloseableIterator<E>	Interface that provides semantics of a Iterator and AutoCloseable interfaces.
CloseableIteratorCollection<E>	A collection that defines an iterator method that returns a CloseableIterator instead of a non closeable one.
CloseableIteratorSet<E>	A set that defines an iterator method that returns a CloseableIterator instead of a non closeable one.
CloseableSpliterator<T>	Interface that provides semantics of a Spliterator and AutoCloseable interfaces.
EntrySizeCalculator<K,V>
EvictionListener<K,V>	Deprecated. since 10.0 - This class is not used internally anymore
FileLookup
Immutables.Immutable
InfinispanCollections.Function<E,T>	A function that converts a type into another one.
InfinispanCollections.MapMakerFunction<K,V,E>	A function that converts an entry into a key/value pair for use in a map.
InjectiveFunction<T,R>	This is a marker interface to be used with Function which signals to some implementors that the function returns distinct values.
IntSet	A set that represents primitive ints.
PeekableMap<K,V>	Deprecated. since 11.0 with no replacement - no longer used
ReversibleOrderedSet<E>	A set that allows reverse iteration of the set elements, exposed via the ReversibleOrderedSet.reverseIterator() method.
Util.ByteGetter	Returns the byte at index.
WeakValueHashMap.ValueRef<K,V>

Class Summary

Class	Description
AbstractDelegatingCollection<E>	Delegating collection that delegates all calls to the collection returned from AbstractDelegatingCollection.delegate()
AbstractDelegatingConcurrentMap<K,V>
AbstractDelegatingMap<K,V>
AbstractDelegatingSet<E>
AbstractEntrySizeCalculatorHelper<K,V>	Abstract class that provides a method to round up to the nearest value of 8 which is important for most jvm when doing size calculations.
AbstractFileLookup
AbstractIterator<E>	Abstract iterator that allows overriding just the AbstractIterator.getNext() method to implement it.
AbstractMap<K,V>	Similar to the JDK's AbstractMap, this provides common functionality for custom map implementations.
AbstractMap.SimpleEntry<K,V>
AggregatedClassLoader	A ClassLoader that delegates loading of classes and resources to a list of delegate ClassLoaders.
ArrayCollector
ArrayMap<K,V>	Base for classes that implement hash map by storing keys in one array and values in another.
BeanUtils	Simple JavaBean manipulation helper methods
BloomFilter<E>
ByRef<T>	This class can be used to pass an argument by reference.
ByRef.Boolean	Implementation for primitive type
ByRef.Integer
ByRef.Long
ByteQuantity	Parser human-readable quantity of bytes.
ClassFinder	Find infinispan classes utility
ClasspathURLStreamHandler	A URLStreamHandlerFactory which can handle classpath: URI schemes.
CloseableIteratorCollectionAdapter<E>	Adapts Collection to CloseableIteratorCollection
CloseableIteratorSetAdapter<E>	Adapts Set to CloseableIteratorSet
Closeables	This class consists exclusively of static methods that operate on or return closeable interfaces.
ConcatIterator<E>	Iterator that concatenates a bunch of iterables into 1 big iterator.
Either<A,B>
EnumerationList<T>	An Enumeration → List adaptor
EnumUtil	Utilities method to Enums.
FastCopyHashMap<K,V>	A HashMap that is optimized for fast shallow copies.
Features	Features allow conditional enabling/disabling of Infinispan's functionality.
FileLookupFactory
FileLookupFactory.DefaultFileLookup
FilterIterator<E>	Iterator that also filters out entries based on the provided predicate.
FilterSpliterator<T>	Spliterator that only returns entries that pass the given predicate.
FlattenSpliterator<E>	Composes an array of Collections into a spliterator.
ForwardingList<E>	A list which forwards all its method calls to another list.
GlobUtils	Utility functions for globs
HopscotchHashMap<K,V>	Lookup on a table without collisions will require only single access, if there are collisions it will be limited to (number of collisions to particular bin + 1) and all those will lie in proximity (32 * reference size).
ImmutableHopscotchHashSet<E>	Wrap a HopscotchHashMap and allow using it as a Set.
ImmutableIntSet	Deprecated. since 9.3 This class will no longer be public, please use IntSets.immutableSet(IntSet)

ImmutableListCopy.Externalizer
Immutables	Factory for generating immutable type wrappers.
Immutables.ImmutableIteratorWrapper<E>
Immutables.ImmutableMapWrapperExternalizer
Immutables.ImmutableSetWrapperExternalizer
InfinispanCollections	Static helpers for Infinispan-specific collections
InstanceSupplier<T>
IntSets	Static utility class for creating various IntSet objects.
IntSetsExternalization	IntSets externalization mechanism
IteratorMapper<E,S>	A iterator that maps each value to the output of the Function.
JVMMemoryInfoInfo
KeyValueWithPrevious<K,V>
LegacyKeySupportSystemProperties	A wrapper around system properties that supports legacy keys
MurmurHash3BloomFilter	BloomFilter implementation that allows for up to 10 hash functions all using MurmurHash3 with different seeds.
NullValue	A placeholder for null in a cache, because caches do not allow null values.

Proxies	Proxies is a collection of useful dynamic profixes.
RangeSet	Deprecated. since 9.3 This class will no longer be public.
ReflectionUtil	Basic reflection utilities to enhance what the JDK provides.
RemovableCloseableIterator<C>	A CloseableIterator implementation that allows for a CloseableIterator that doesn't allow remove operations to implement remove by delegating the call to the provided consumer to remove the previously read value.
RemovableIterator<C>	An Iterator implementation that allows for a Iterator that doesn't allow remove operations to implement remove by delegating the call to the provided consumer to remove the previously read value.
