Class	Description
AbstractConstant<T extends AbstractConstant<T>>	Base implementation of Constant.
AbstractReferenceCounted	Abstract base class for classes wants to implement ReferenceCounted.
AsciiString	A string which has been encoded into a character encoding whose character always takes a single byte, similarly to ASCII.
AsyncMapping<IN,OUT>
Attribute<T>	An attribute which allows to store a value reference.
AttributeKey<T>	Key which can be used to access Attribute out of the AttributeMap.
AttributeMap	Holds Attributes which can be accessed via AttributeKey.
BooleanSupplier	Represents a supplier of boolean-valued results.
ByteProcessor	Provides a mechanism to iterate over a collection of bytes.
ByteProcessor.IndexNotOfProcessor	A ByteProcessor which finds the first appearance which is not of a specific byte.
ByteProcessor.IndexOfProcessor	A ByteProcessor which finds the first appearance of a specific byte.
CharsetUtil	A utility class that provides various common operations and constants related with Charset and its relevant classes.
Constant<T extends Constant<T>>	A singleton which is safe to compare via the == operator.
ConstantPool<T extends Constant<T>>	A pool of Constants.
DefaultAttributeMap	Default AttributeMap implementation which not exibit any blocking behaviour on attribute lookup while using a copy-on-write approach on the modify path. Attributes lookup and remove exibit O(logn) time worst-case complexity, hence attribute::set(null) is to be preferred to remove.

HashedWheelTimer	A Timer optimized for approximated I/O timeout scheduling.
HashingStrategy<T>	Abstraction for hash code generation and equality comparison.
IllegalReferenceCountException	An IllegalStateException which is raised when a user attempts to access a ReferenceCounted whose reference count has been decreased to 0 (and consequently freed).
IntSupplier	Represents a supplier of int-valued results.
LeakPresenceDetector<T>	Alternative leak detector implementation for reliable and performant detection in tests.
LeakPresenceDetector.AllocationProhibitedException	Special exception type to show that an allocation is prohibited at the moment, for example because the LeakPresenceDetector.ResourceScope is closed, or because the current thread cannot be associated with a particular scope.
LeakPresenceDetector.ResourceScope	A resource scope keeps track of the resources for a particular set of threads.
Mapping<IN,OUT>	Maintains the mapping from the objects of one type to the objects of the other type.

TimerTask	A task which is executed after the delay specified with Timer.newTimeout(TimerTask, long, TimeUnit).
UncheckedBooleanSupplier	Represents a supplier of boolean-valued results which doesn't throw any checked exceptions.
Version	Retrieves the version information of available Netty artifacts.
