SReference

```
public interface SReference
```
Represents reference between nodes. Nodes are organized in AST with references going across the tree hierarchy and connecting nodes from different branches or trees.

Method Summary

All Methods Instance Methods Abstract Methods Deprecated Methods
Modifier and Type	Method	Description
`SReferenceLink`	`getLink()`	Gets the associated Link - an abstract meta-definition for the reference
`String`	`getRole()`	Deprecated.
`SNode`	`getSourceNode()`	Containing node for this reference.
`SNode`	`getTargetNode()`	Resolves the target node in the containing repository.
`SNodeId`	`getTargetNodeId()`
`SNodeReference`	`getTargetNodeReference()`	Builds and returns a reference to the target node.
`SModelReference`	`getTargetSModelReference()`	The following two operations are defined only for references which can instantly respond to the request (e.g.

- Method Detail
  - getRole
```
@Deprecated
String getRole()
```
    Deprecated.
  - getLink
```
SReferenceLink getLink()
```
    Gets the associated Link - an abstract meta-definition for the reference
  - getSourceNode
```
SNode getSourceNode()
```
    Containing node for this reference.
  - getTargetNode
```
SNode getTargetNode()
```
    Resolves the target node in the containing repository. This operation is not guaranteed to be fast. It may require to traverse the repository, compute types for some nodes or execute code provided by the language-designer.
    
    Returns:
    
    the node behind the reference, or null if something is broken in the repository
  - getTargetNodeReference
```
SNodeReference getTargetNodeReference()
```
    Builds and returns a reference to the target node. Tries to avoid lengthy computations whenever possible. Does exactly the same as getTargetNode().getReference(), but probably faster.
  - getTargetSModelReference
```
@Nullable
SModelReference getTargetSModelReference()
```
    The following two operations are defined only for references which can instantly respond to the request (e.g. they store the target model reference and/or node id as a part of the reference).
    
    Returns:
    
    target model reference (if available)
  - getTargetNodeId
```
@Nullable
SNodeId getTargetNodeId()
```
