| === Languages |
| |
| To support flexible and powerful |
| link:enterprise-integration-patterns.adoc[Enterprise Integration |
| Patterns], Camel supports various Languages to create an |
| link:expression.adoc[Expression] or link:predicate.adoc[Predicate] |
| within either the link:dsl.adoc[Routing Domain Specific Language] or the |
| link:xml-configuration.adoc[XML Configuration]. |
| |
| ==== Note |
| *Combining Predicates** |
| |
| When creating predicates (expressions that evaluate to `true` or |
| `false`), you can combine several predicates -- regardless of the |
| language they are built with -- by using the `PredicateBuilder` class. |
| For more information, see link:predicate.adoc[Compound Predicates]. |
