Class EvalVisitor

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.
