Endpoint Annotations

You can annotate Endpoint and Consumer classes so that their configuration documentation can be automatically generated by the camel-package-maven-plugin (rather like maven plugin goals get their parameters documented automatically).

The documentation is then included into the jar as org/apache/camel/component/scheme/scheme.adoc where scheme is the component name.

Supported annotations

Annotation Description

@UriEndpoint

Specifies that an endpoint is annotated with @UriParam and/or @UriParams annotations. Also specifies the default scheme to use in the generated documentation, and other informations

@UriParam

Used to annotate a parameter value; usually specified via ?foo=bar syntax in the URI strings in Camel. Used currently only on field declarations but in the future could be used on setter methods too. If no name is specified then the name of the field/setter property is used.

@UriParams

Specifies that a field is a nested object of one or more configuration parameters; then the class of this field should be annotated with one or more @UriParam or @UriParams annotations

@Metadata

Used for special situations to provide additional information

For example see the TimerEndpoint from the camel-timer component and notice how its using these annotations.

Not only are the annotations useful for automatically generating the documentation; we can use them to refine the validation of the code during configuration and they can be useful for tool providers so they can more easily introspect the configuration options.
