| :description: Fast case-insensitive headers map implementation |
| :since: 2.20 |
| :supportLevel: Stable |
| |
| *Since Camel {since}* |
| |
| The camel-headersmap is a faster implementation of a case-insenstive map which can be plugged in |
| and used by Camel at runtime to have slight faster performance in the Camel Message headers. |
| |
| == Auto detection from classpath |
| |
| To use this implementation all you need to do is to add the `camel-headersmap` dependency to the classpath, |
| and Camel should auto-detect this on startup and log as follows: |
| |
| [source,text] |
| ---- |
| Detected and using HeadersMapFactory: camel-headersmap |
| ---- |
| |
| == Manual enabling |
| |
| If you use OSGi or the implementation is not added to the classpath, you need to enable this explicit such: |
| |
| [source,java] |
| ---- |
| CamelContext camel = ... |
| |
| camel.setHeadersMapFactory(new FastHeadersMapFactory()); |
| ---- |
| |
| Or in XML DSL (spring or blueprint XML file) you can declare the factory as a `<bean>`: |
| |
| [source,xml] |
| ---- |
| <bean id="fastMapFactory" class="org.apache.camel.component.headersmap.FastHeadersMapFactory"/> |
| ---- |
| |
| and then Camel should detect the bean and use the factory. |
