# Package com.sun.jdi.request

package com.sun.jdi.request
This package is used to request that a JDI event be sent under specified conditions. With the exception of termination events, which are always sent, there is one kind of `EventRequest` for each kind of `Event` - for example, `BreakpointRequest` is used to request a `BreakpointEvent`. Event requests are created by the `EventRequestManager`. Events and event processing are defined in the `com.sun.jdi.event` package.

Methods may be added to the interfaces in the JDI packages in future releases. Existing packages may be renamed if the JDI becomes a standard extension.

Since:
  1.3
