EvalVisitor (Closure Templates)

java.lang.Object
- com.google.template.soy.basetree.AbstractReturningNodeVisitor<ExprNode,R>
- - com.google.template.soy.exprtree.AbstractReturningExprNodeVisitor<SoyValue>
  - - com.google.template.soy.sharedpasses.render.EvalVisitor

All Implemented Interfaces:

NodeVisitor<ExprNode,SoyValue>
```
public class EvalVisitor
extends AbstractReturningExprNodeVisitor<SoyValue>
```
Visitor for evaluating the expression rooted at a given ExprNode.
Important: Do not use outside of Soy code (treat as superpackage-private).
AbstractReturningNodeVisitor.exec(N) may be called on any expression. The result of evaluating the expression (in the context of the data and env passed into the constructor) is returned as a SoyValue object.
