EMFModelReader

- com.sodius.mdw.core.model.emf.EMFModelReader

All Implemented Interfaces:

ModelReader

Direct Known Subclasses:

EMFXMIModelReader, EMFXMLModelReader
```
public abstract class EMFModelReader
extends Object
implements ModelReader
```
Provides a skeletal implementation for EMF based model readers.
This class acts as a bridge between EMF Resource and MDWorkbench ModelReader. Subclasses are required to implement the createResource method. This class will delegate the loading to the created resource. Then it will attach to the model every created EMF model element.

A default implementation is available to handle XMI uris.

Clients may subclass this class.

- Field Detail
  - MDW_CONNECTOR_CONTEXT
```
public static final String MDW_CONNECTOR_CONTEXT
```
    Option that gives access to the connector context. A resource load method can retrieve the connector context this way :
    ConnectorContext context = (ConnectorContext) options.get(EMFModelReader.MDW_CONNECTOR_CONTEXT);

- Method Detail
  - read
```
public void read(String filepath,
                 Model model,
                 ConnectorContext context)
          throws CoreException
```
    Reads the specified uri. This implementation reads a model in four steps :
    - creates a Resource.
    - creates options to pass to the resource.
    - calls resource load method.
    - attach resource model elements to the specified model.
    The context can be used to access a variery of properties and is to be used to check for cancellation.
    Specified by:
    
    read in interface ModelReader
    
    Parameters:
    
    filepath - the location of a resource to read.
    
    model - the model in which model elements must be created.
    
    context - the context in which this reader runs.
    
    Throws:
    
    CoreException - if anything prevents the connector to read the model.

  - createResourceSet
```
protected ResourceSet createResourceSet(Model model,
                                        ConnectorContext context)
```
    Creates a resource set based on this connector context
    
    Parameters:
    
    model - the model in which model elements must be created.
    
    context - the connector context to use.
    
    Returns:
    
    a resource set used to create a resource.
  - createResource
```
protected abstract Resource createResource(URI uri,
                                           ConnectorContext context)
```
    Creates a resource that is able to handle the specified uri.
    
    Parameters:
    
    uri - the URI to load.
    
    context - the context in which the connector runs
    
    Returns:
    
    the created resource.
  - createOptions
```
protected Map<String,Object> createOptions(ConnectorContext context)
```
    Create options to pass to the created resource. The default implementation set as option every property defined on the connector context, and add MDW_CONNECTOR_CONTEXT to give access to the context.
    
    Parameters:
    
    context - the context in which the connector runs
    
    Returns:
    
    the options to pass to the resource.
  - logError
```
protected void logError(ConnectorContext context,
                        Resource.Diagnostic error)
```
    Logs the specified diagnostic to the registered logger.
    
    Parameters:
    
    context - the context in which this reader runs.
    
    error - the error to be logged.
