Class ExprEquivalence

java.lang.Object

com.google.common.base.Equivalence<ExprNode>

com.google.template.soy.exprtree.ExprEquivalence

All Implemented Interfaces:

BiPredicate<ExprNode,ExprNode>

public final class ExprEquivalence
extends com.google.common.base.Equivalence<ExprNode>

An equivalence relation for expressions.

This equivalence relation is meant to identify identical subexpressions and as such we ignore a number of ExprNode properties. For example:

• Node.getSourceLocation()
• ExprNode.getType()
• ExprNode.getParent()
