Interface IWorkingCopyManager

public interface IWorkingCopyManager

Interface for accessing working copies of ICompilationUnit objects. The original compilation unit is only given indirectly by means of an IEditorInput. The life cycle is as follows:

• connect creates and remembers a working copy of the compilation unit which is encoded in the given editor input
• getWorkingCopy returns the working copy remembered on connect
• disconnect destroys the working copy remembered on connect

In order to provide backward compatibility for clients of IWorkingCopyManager, extension interfaces are used to provide a means of evolution. The following extension interfaces exist:

• IWorkingCopyManagerExtension since version 2.1 introducing API to set and remove the working copy for a given editor input.

This interface is not intended to be implemented by clients.

Method Detail

connect

void connect(IEditorInput input)
      throws CoreException

Connects the given editor input to this manager. After calling this method, a working copy will be available for the compilation unit encoded in the given editor input (does nothing if there is no encoded compilation unit).

Parameters:

input - the editor input

Throws:

CoreException - if the working copy cannot be created for the compilation unit

disconnect

void disconnect(IEditorInput input)

Disconnects the given editor input from this manager. After calling this method, a working copy for the compilation unit encoded in the given editor input will no longer be available. Does nothing if there is no encoded compilation unit, or if there is no remembered working copy for the compilation unit.

Parameters:

input - the editor input

getWorkingCopy

ICompilationUnit getWorkingCopy(IEditorInput input)

Returns the working copy remembered for the compilation unit encoded in the given editor input.

Parameters:

input - the editor input

Returns:

the working copy of the compilation unit, or null if the input does not encode an editor input, or if there is no remembered working copy for this compilation unit

shutdown

void shutdown()

Shuts down this working copy manager. All working copies still remembered by this manager are destroyed.
