Chapter 47. Component Interface
Abstract
This chapter describes how to implement the
Component interface.
47.1. The Component Interface
Overview
To implement a Apache Camel component, you must implement the
org.apache.camel.Component interface. An instance of Component type provides the entry point into a custom component. That is, all of the other objects in a component are ultimately accessible through the Component instance. Figure 47.1, “Component Inheritance Hierarchy” shows the relevant Java interfaces and classes that make up the Component inheritance hierarchy.

The Component interface
Example 47.1, “Component Interface” shows the definition of the
org.apache.camel.Component interface.
Example 47.1. Component Interface
package org.apache.camel;
public interface Component {
CamelContext getCamelContext();
void setCamelContext(CamelContext context);
Endpoint createEndpoint(String uri) throws Exception;
}Component methods
The
Component interface defines the following methods:
getCamelContext()andsetCamelContext()—References theCamelContextto which thisComponentbelongs. ThesetCamelContext()method is automatically called when you add the component to aCamelContext.createEndpoint()—The factory method that gets called to createEndpointinstances for this component. Theuriparameter is the endpoint URI, which contains the details required to create the endpoint.
