```
public class ConstantDefinitions
extends java.lang.Object

  - getConstantMultimap
```
public com.google.common.collect.Multimap<java.lang.String,CssDefinitionNode> getConstantMultimap()
```
  - getConstantDefinition
```
public CssDefinitionNode getConstantDefinition(java.lang.String constant)
```
    Returns the last definition of a constant. Callers should not attempt to modify the returned value.
    
    Returns:
    
    definition node or null if the constant is not defined
  - getConstantDefinitions
```
public java.util.List<CssDefinitionNode> getConstantDefinitions(java.lang.String constant)
```
    Returns all definitions of a constant.
    
    Returns:
    
    collection of definition node or empty collection if the constant is not defined
  - addConstantDefinition
```
public void addConstantDefinition(CssDefinitionNode definition)
```
    Adds a constant definition to this css tree.
    Note that a constant may be defined multiple times in the tree. For the compact representation of the tree, all references to a constant will be replaced with the same value: the last one specified in the stylesheet (to ignore the definitions in inactive condition blocks the EliminateConditionalNodes compiler pass needs to be run first).
  - getConstantsNames
```
public java.lang.Iterable<java.lang.String> getConstantsNames()
```
    Returns:
    
    the iterable of names of all defined constants
