The * VirtualMachineManager allows one application to debug * multiple target VMs. (Note that the converse is not * supported; a target VM can be debugged by only one * debugger application.) This interface * contains methods to manage connections * to remote target VMs and to obtain the {@link VirtualMachine} * mirror for available target VMs. * <p> * Connections can be made using one of several different * {@link Connector} objects. Each connector encapsulates * a different way of connecting the debugger with a target VM. * <p> * The VirtualMachineManager supports many different scenarios for * connecting a debugger to a virtual machine.

That is, they * are created the first time that {@link * Bootstrap#virtualMachineManager()} is invoked. * The list of all Connectors created at start-up time can be * obtained from the VirtualMachineManager by invoking the * {@link #allConnectors allConnectors} method. * * <p> Connectors are created at start-up time if they are * installed on the platform. In addition, Connectors are created * automatically by the VirtualMachineManager to encapsulate any * {@link TransportService} implementations * that are installed on the platform. These two mechanisms for * creating Connectors are described here. * * <p> A Connector is installed on the platform if it is installed * in a jar file that is visible to the defining class loader of * the {@link Connector} type, * and that jar file contains a provider configuration file named * {@code Connector} in the resource directory * {@code META-INF/services}, and the provider configuration file * lists the full-qualified class name of the Connector * implementation. A Connector is a class that implements the * {@link Connector Connector} interface. More * appropriately the class implements one of the specific Connector * types, namely {@link AttachingConnector * AttachingConnector}, {@link ListeningConnector * ListeningConnector}, or {@link LaunchingConnector * LaunchingConnector}. The format of the provider configuration file * is one fully-qualified class name per line. Space and tab characters * surrounding each class, as well as blank lines are ignored. The * comment character is {@code '#'} ({@code 0x23}), and on each * line all characters following the first comment character are * ignored. The file must be encoded in UTF-8. * * <p> At start-up time the VirtualMachineManager attempts to load * and instantiate (using the no-arg constructor) each class listed * in the provider configuration file. Exceptions thrown when loading * or creating the Connector are caught and ignored. In other words, * the start-up process continues despite of errors. * * <p> In addition to Connectors installed on the platform the * VirtualMachineManager will also create Connectors to encapsulate * any {@link TransportService} implementations * that are installed on the platform. A TransportService is * installed on the platform if it installed in a jar file that is * visible to the defining class loader for the * {@link TransportService} type, and that jar * file contains a provider configuration file named * {@code TransportService} in the resource * directory {@code META-INF/services}, and the provider * configuration file lists the full-qualified class name of the * TransportService implementation. A TransportService is a concrete * sub-class of {@link TransportService * TransportService}. The format of the provider configuration file * is the same as the provider configuration file for Connectors * except that each class listed must be the fully-qualified class * name of a class that implements the TransportService interface. * * <p> For each TransportService installed on the platform, the * VirtualMachineManager creates a corresponding {@link AttachingConnector} and * {@link ListeningConnector}. These Connectors are created to encapsulate a * {@link Transport Transport} that in turn encapsulates the TransportService. * The AttachingConnector will be named based on the name of the * transport service concatenated with the string {@code Attach}. * For example, if the transport service {@link * TransportService#name() name()} method * returns {@code telepathic} then the AttachingConnector will * be named {@code telepathicAttach}. Similiarly the ListeningConnector * will be named with the string {@code Listen} tagged onto the * name of the transport service. The {@link * Connector#description() description()} method * of both the AttachingConnector, and the ListeningConnector, will * delegate to the {@link TransportService#description() * description()} method of the underlying transport service. Both * the AttachingConnector and the ListeningConnector will have two * Connector {@link com.sun.jdi.connect.Connector.Argument Arguments}. * A {@link com.sun.jdi.connect.Connector.StringArgument StringArgument} * named {@code address} is the connector argument to specify the * address to attach too, or to listen on. A * {@link com.sun.jdi.connect.Connector.IntegerArgument IntegerArgument} * named {@code timeout} is the connector argument to specify the * timeout when attaching, or accepting. The timeout connector may be * ignored depending on if the transport service supports an attach * timeout or accept timeout. * * <p> Initialization of the virtual machine manager will fail, that is * {@link Bootstrap#virtualMachineManager()} will throw an * error if the virtual machine manager is unable to create any * connectors. * * @author Gordon Hirsch * @since 1.3 */ public interface VirtualMachineManager { /** * Identifies the default connector.
