Context (Apache Tomcat 10.1.39 API Documentation)
Description: declaration: package: org.apache.catalina, interface: Context

# Interface Context

All Superinterfaces:
  `Container`, `ContextBind`, `Lifecycle`

All Known Implementing Classes:
  `FailedContext`, `ReplicatedContext`, `StandardContext`

public interface Context extends Container, ContextBind
A Context is a Container that represents a servlet context, and therefore an individual web application, in the Catalina servlet engine. It is therefore useful in almost every deployment of Catalina (even if a Connector attached to a web server (such as Apache) uses the web server's facilities to identify the appropriate Wrapper to handle this request. It also provides a convenient mechanism to use Interceptors that see every request processed by this particular web application.

The parent Container attached to a Context is generally a Host, but may be some other implementation, or may be omitted if it is not necessary.

The child containers attached to a Context are generally implementations of Wrapper (representing individual servlet definitions).
