Package io.netty.channel
Interface ChannelId
- All Superinterfaces:
Comparable<ChannelId>
,Serializable
- All Known Implementing Classes:
DefaultChannelId
,EmbeddedChannelId
,Http2StreamChannelId
Represents the globally unique identifier of a
Channel
.
The identifier is generated from various sources listed in the following:
- MAC address (EUI-48 or EUI-64) or the network adapter, preferably a globally unique one,
- the current process ID,
System.currentTimeMillis()
,System.nanoTime()
,- a random 32-bit integer, and
- a sequentially incremented 32-bit integer.
The global uniqueness of the generated identifier mostly depends on the MAC address and the current process ID, which are auto-detected at the class-loading time in best-effort manner. If all attempts to acquire them fail, a warning message is logged, and random values will be used instead. Alternatively, you can specify them manually via system properties:
io.netty.machineId
- hexadecimal representation of 48 (or 64) bit integer, optionally separated by colon or hyphen.io.netty.processId
- an integer between 0 and 65535
