- com.google.common.css.compiler.ast.CssNode
- - com.google.common.css.compiler.ast.CssValueNode
  - - com.google.common.css.compiler.ast.CssConstantReferenceNode

All Implemented Interfaces:

Locatable
```
public class CssConstantReferenceNode
extends CssValueNode
```
A node holding a reference to a constant or an argument of a mixin definition.
Because references can be valid within one block, each reference has a scope where it is valid. For example, references to arguments of mixin definitions are only valid in the block of the mixin definition whereas references to global definitions are valid everywhere.

    Parameters:
    
    node - node
- Method Detail
  - deepCopy
```
public CssConstantReferenceNode deepCopy()
```
    Specified by:
    
    deepCopy in class CssValueNode
  - getScope
```
public CssNode getScope()
```
    Returns the scope of the reference. If the reference belongs to a global definition, the scope is the 'global scope'. If the reference belongs to an argument of a mixin definition, the scope is the mixin definition.
    
    Returns:
    
    scope
  - setScope
```
public void setScope(CssNode scope)
```
  - isDefinitionReference
```
public static boolean isDefinitionReference(java.lang.String ident)
```
    Returns if the given identifier matches the pattern of a constant.
    
    Parameters:
    
    ident - identifier
