Package com.sun.jdi

package com.sun.jdi

This is the core package of the Java Debug Interface (JDI), it defines mirrors for values, types, and the target VirtualMachine itself - as well bootstrapping facilities. VirtualMachine mirrors the target virtual machine and is the origin of all information provided by the JDI. A VirtualMachine is typically created by using the VirtualMachineManager to create a connection to the target virtual machine (see the com.sun.jdi.connect package). In turn the VirtualMachineManager is typically created by calling Bootstrap.virtualMachineManager().

Most of the methods within this package can throw the unchecked exception VMDisconnectedException.

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.
