org.eclipse.jdt.launching
Class VMStandin

java.lang.Object
  org.eclipse.jdt.launching.AbstractVMInstall
      org.eclipse.jdt.launching.VMStandin

All Implemented Interfaces:

IVMInstall

public class VMStandin

extends AbstractVMInstall

An implementation of IVMInstall that is used for manipulating VMs without necessarily committing changes.

Instances of this class act like wrappers. All other instances of IVMInstall represent 'real live' VMs that may be used for building or launching. Instances of this class behave like 'temporary' VMs that are not visible and not available for building or launching.

Instances of this class may be constructed as a preliminary step to creating a 'live' VM or as a preliminary step to making changes to a 'real' VM.

When convertToRealVM is called, a corresponding 'real' VM is created if one did not previously exist, or the corresponding 'real' VM is updated.

Clients may instantiate this class; it is not intended to be subclassed.

Since:

2.1

VMStandin

public VMStandin(IVMInstall realVM)

Construct a VMStandin instance based on the specified IVMInstall. Changes to this standin will not be reflected in the 'real' VM until convertToRealVM is called.

Parameters:

realVM - the 'real' VM from which to construct this standin VM

Method Detail

convertToRealVM

public IVMInstall convertToRealVM()

If no corresponding 'real' VM exists, create one and populate it from this standin instance. If a corresponding VM exists, update its attributes from this standin instance.

Returns:

IVMInstall the 'real' corresponding to this standin VM
