Class SoyTypes.SoyTypeEqualComparisonOp

java.lang.Object

com.google.template.soy.types.SoyTypes.SoyTypeEqualComparisonOp

All Implemented Interfaces:

SoyTypes.SoyTypeBinaryOperator

Enclosing class:

SoyTypes

public static final class SoyTypes.SoyTypeEqualComparisonOp
extends Object
implements SoyTypes.SoyTypeBinaryOperator

Type resolver for equal (==) and not equal (!=) operators. The resolver returns null if two SoyType instances are not comparable, otherwise always return BoolType.

In particular,

• Comparing anything with UNKNOWN, ANY, and NULL is legitimate.
• If one is assignable from another, comparing them is legitimate.
• If both are primitive types, comparing them is legitimate.
• All other comparisons should have exactly the same types on both sides. Coercing is unsafe, especially in JS backend. An example is a jspb message that contains a single enum. Assuming that the enum is 1, the representation in JS is [1], and this is equivalent to a number.
