BinaryHeaderMap (co.elastic.apm:elastic-apm-agent 1.21.0 API)

java.lang.Object
- co.elastic.apm.agent.util.BinaryHeaderMap

All Implemented Interfaces:

Recyclable, java.lang.Iterable<BinaryHeaderMap.Entry>
```
public class BinaryHeaderMap
extends java.lang.Object
implements Recyclable, java.lang.Iterable<BinaryHeaderMap.Entry>
```
A map (not implementing the java.util.Map interface) that only supports String-byte[] pair additions and iterations. The map doesn't allocate during addition or iteration. This map does not support any form of concurrency. It can be either be in a write mode (through its add(java.lang.String, byte[]) method) or read mode (through the iterator() API) at a given time. Reads and writes must not be performed by more than one thread concurrently.
NOTE: this map does not guarantee visibility, therefore ensuring visibility when switching from read to write mode (or the other way around) is under the responsibility of the map's user.
