Class ProbeFilter

java.lang.Object

org.jboss.weld.probe.ProbeFilter

All Implemented Interfaces:

javax.servlet.Filter

@Vetoed
public class ProbeFilter
extends Object
implements javax.servlet.Filter

This filter takes care of the servlet integration. Basically, it:

• implements a simple REST API,
• allows to group together monitored invocations within the same request,
• allows to embed an informative HTML snippet to every response with Content-Type of value text/html.

An integrator is required to register this filter. The filter should only be mapped to a single URL pattern of value /*.

To disable the clippy support, set ConfigurationKey.PROBE_EMBED_INFO_SNIPPET to false. It's also possible to use the ConfigurationKey.PROBE_INVOCATION_MONITOR_EXCLUDE_TYPE to skip the monitoring.
