Uses of HttpHeaders in io.netty.handler.codec.http

Subclasses of HttpHeaders in io.netty.handler.codec.http

Modifier and Type	Class and Description
class	CombinedHttpHeaders Will add multiple values for the same header as single header with a comma separated list of values.
class	DefaultHttpHeaders Default implementation of HttpHeaders.
class	EmptyHttpHeaders
class	ReadOnlyHttpHeaders A variant of HttpHeaders which only supports read-only methods.

Fields in io.netty.handler.codec.http declared as HttpHeaders

Modifier and Type	Field and Description
static HttpHeaders	HttpHeaders.EMPTY_HEADERS Deprecated. Use EmptyHttpHeaders.INSTANCE. The instance is instantiated here to break the cyclic static initialization between EmptyHttpHeaders and HttpHeaders. The issue is that if someone accesses EmptyHttpHeaders.INSTANCE before EMPTY_HEADERS then EMPTY_HEADERS will be null.
