Interface Summary

Interface	Description
AsyncMapping<IN,OUT>
Attribute<T>	An attribute which allows to store a value reference.
AttributeMap	Holds Attributes which can be accessed via AttributeKey.
ByteProcessor	Provides a mechanism to iterate over a collection of bytes.
Constant<T extends Constant<T>>	A singleton which is safe to compare via the == operator.
HashingStrategy<T>	Abstraction for hash code generation and equality comparison.
Mapping<IN,OUT>	Maintains the mapping from the objects of one type to the objects of the other type.
Recycler.Handle<T>
ReferenceCounted	A reference-counted object that requires explicit deallocation.
Resource<T extends Resource<T>>	A resource that has a life-time, and can be closed.
ResourceLeakHint	A hint object that provides human-readable message for easier resource leak tracking.
ResourceLeakTracker<T>
SafeCloseable	A SafeCloseable can be safely closed without risk of an exception being thrown.
Send<T extends Resource<T>>	A temporary holder of a Resource, used for transferring the ownership of the resource from one thread to another.
Timeout	A handle associated with a TimerTask that is returned by a Timer.
Timer	Schedules TimerTasks for one-time future execution in a background thread.
TimerTask	A task which is executed after the delay specified with Timer.newTimeout(TimerTask, long, TimeUnit).

Class Summary

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.
AttributeKey<T>	Key which can be used to access Attribute out of the AttributeMap.
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.
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.
DomainMappingBuilder<V>	Deprecated. Use DomainWildcardMappingBuilder instead.
DomainNameMapping<V>	Deprecated. Use DomainWildcardMappingBuilder}
DomainNameMappingBuilder<V>	Deprecated. Use DomainWildcardMappingBuilder
DomainWildcardMappingBuilder<V>	Builder that allows to build Mappings that support DNS wildcard matching.
HashedWheelTimer	A Timer optimized for approximated I/O timeout scheduling.
NettyRuntime	A utility class for wrapping calls to Runtime.
NetUtil	A class that holds a number of network-related constants.
Recycler<T>	Light-weight object pool based on a thread-local stack.
ReferenceCountUtil	Collection of method to handle objects that may implement ReferenceCounted.
ResourceLeakDetector<T>
ResourceLeakDetectorFactory	This static factory should be used to load ResourceLeakDetectors as needed
Version	Retrieves the version information of available Netty artifacts.

Enum Summary

Enum	Description
ResourceLeakDetector.Level	Represents the level of resource leak detection.

Exception Summary

Exception	Description
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).

Annotation Types Summary

Annotation Type	Description
SuppressForbidden	Annotation to suppress forbidden-apis errors inside a whole class, a method, or a field.
