Nested Classes

Modifier and Type	Class	Description
(package private) static final class	Http2ConnectionPropertyKeys.GlobalPropertyKey	Implementation of Http2Connection.PropertyKey that specifies the index position of the property and, unlike DefaultHttp2Connection.DefaultPropertyKey, is not tied to a specific Http2Connection.

Field Summary

Fields

Modifier and Type	Field	Description
private static final int	MAX_GLOBAL_KEYS	Safe-guard against misuse: global keys are expected to be created rarely, typically once per use-case and stored in a static field, so there should never be a legitimate need for more than this many.
private static final AtomicInteger	nextIndex

Modifier and Type	Method	Description
(package private) static int	keyCount()	The number of keys created via newGlobalKey() so far, which also doubles as the exclusive upper bound for Http2ConnectionPropertyKeys.GlobalPropertyKey.index.
(package private) static Http2Connection.PropertyKey	newGlobalKey()	Creates a new key that, unlike one returned by Http2Connection.newKey(), is not tied to a specific Http2Connection instance.

Method Details

newGlobalKey

static Http2Connection.PropertyKey newGlobalKey()

Creates a new key that, unlike one returned by Http2Connection.newKey(), is not tied to a specific Http2Connection instance. The returned key can be used with the streams of any Http2Connection, which makes it suitable for cases where a key needs to be shared, e.g. stored in a static field, across multiple connections, or created before a Http2Connection instance is even available.

Accessing a property that is associated with a key returned by this method is slower than accessing one associated with a key returned by Http2Connection.newKey(). Prefer the latter whenever a specific Http2Connection instance is available up-front.

keyCount

static int keyCount()

The number of keys created via newGlobalKey() so far, which also doubles as the exclusive upper bound for Http2ConnectionPropertyKeys.GlobalPropertyKey.index.
