IRepairReferencesProvider

```
public interface IRepairReferencesProvider
```
This provider allows clients top fix proxy references in a model, for example URIs or IDs or both that point to elements in an imported library.
The provider has the option of:
Fixing broken URIs to external resources like imported libraries
Fixing a broken set of IDs in an external resource per resource
Fix both cases

Poll the provider if it can handle (i.e. provides for) a given URI. The provider MAY be polled multiple times if there is a SET of URIs to fix
Request the provider for a correct URI for a given URI. If the URI is already correct, the provider should return null for that case. The provider MAY be polled multiple times if there is a set of potential URIs to fix.
Request the provider for a correct set of fragment IDs that MAP to the given set of broken fragment IDs, per URI. The provider MAY be invoked multiple times if there are multiple URIs, each with it's own set of IDS to fix. The provider should return null for a given set of IDs if NONE of those IDs can be fixed (e.g., all the IDs are already correct). NOTE that the URI passed when requesting a set of fixed fragment IDs is assumed to be the CORRECT URI. If the URI is broken, the URI will be fixed first by requesting the provider in the previous step, and then passed to the provider when requesting the set of fixed IDs.

Note that this provider is invoked on an workspace scope auto repair fix during model marker quick fix. For performance reasons, this means the provider will not be invoked when a model is open.

Modifier and Type	Method and Description
`java.util.Map<java.lang.String,java.lang.String>`	`fixID(org.eclipse.emf.common.util.URI uri, java.util.Set<java.lang.String> brokenIDs)` Given a set of broken IDs for a particular URI, this method should resolve the broken IDs into correct IDs by returning a map of broken IDs versus fixed IDs.
`org.eclipse.emf.common.util.URI`	`fixURI(org.eclipse.emf.common.util.URI uri)` Given a potential broken URI, return the correct URI.
`boolean`	`provides(org.eclipse.emf.common.util.URI uri)` Determines if the given URI can be handled by this provider.

```
boolean provides(org.eclipse.emf.common.util.URI uri)
```
    Determines if the given URI can be handled by this provider.
    This includes cases where the URI is BROKEN or the URI is correct.
    If this provider can recognize a broken URI that needs to be fixed, OR a correct URI whose IDs need to be fixed, it should return true.
    Return false otherwise
    
    Parameters:
    
    uri - that this provider can handle. May or may not be a broken URI, as long as this provider can recognize it and handle it.
    
    Returns:
    
    true if it can be handled, false otherwise

java.util.Map<java.lang.String,java.lang.String> fixID(org.eclipse.emf.common.util.URI uri,
                                                       java.util.Set<java.lang.String> brokenIDs)
```
    Given a set of broken IDs for a particular URI, this method should resolve the broken IDs into correct IDs by returning a map of broken IDs versus fixed IDs.
    IMPORTANT: The Key in the map is the BROKEN ID
    IMPORTANT: The Value in the map is the FIXED ID
    The URI argument is assumed to be the CORRECT, resolvable external resource URI. If the URI pertaining to this set of IDs was also broken, it will first be fixed (see the appropriate fix URI method) and THEN passed into this method.
    To fix the URI if the URI is also broken, see the appropriate API for fixing URI
    This method may be invoked multiple times by the framework if there are several URIs, each with a set of IDs, which this provider can handle, so it is possible to have this provider handle multiple sets of IDs per URI.
    
    Parameters:
    
    uri - pertaining to the set of broken IDs to be fixed. This URI is the CORRECT or FIXED URI.
    
    brokenIDs - to fix for the given URI.
    
    Returns:
    
    map of BROKEN IDs (Key) vs FIXED IDs (Value). Return null or empty map if no IDs are to be fixed (i.e., ALL IDs are already correct).

```
org.eclipse.emf.common.util.URI fixURI(org.eclipse.emf.common.util.URI uri)
```
    Given a potential broken URI, return the correct URI.
    IMPORTANT: the returned URI should be encoded and resolvable in the workspace.
    Return null if the URI is not broken and doesn't need fixing.
    
    Parameters:
    
    uri - to fix.
    
    Returns:
    
    correct URI or null if URI argument is not broken
