final class Http2ConnectionPropertyKeys
extends java.lang.Object

Utility methods for creating Http2Connection.PropertyKeys.

Nested Class Summary

Nested Classes
Modifier and Type	Class	Description
`(package private) static 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 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 java.util.concurrent.atomic.AtomicInteger`	`nextIndex`

Method Summary

All Methods Static Methods Concrete Methods
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.

```
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.
