Esper Common 9.0.0 API
Esper Common API - Common to the compiler API and the runtime API
The common API consists of packages undercom.espertech.esper.common.client.
The classes and interfaces in the common API client packages are fully intended to be exposed to application code
and are classes that are generally relevant to both the compiler API and the runtime API.
The
com.espertech.esper.common.client.hook package contains Extension API
is intended to be used by application programmers to extend functionality.
The extension API is less stable than the other client API classes.The classes under
com.espertech.esper.common.internal are not intended for use by an application unless the application builds an extension. The internal API classes are not stable
and can change significantly between versions.
Full documentation may be found at the home page.
