Class: Mongory::Matchers::EqMatcher

Inherits:
AbstractMatcher show all
Defined in:
lib/mongory/matchers/eq_matcher.rb

Overview

Note:

This matcher is also used as the fallback for non-operator literal values, such as { name: "Alice" }, when no other specialized matcher is applicable.

Note:

Equality behavior depends on how == is implemented for the given objects.

EqMatcher matches values using the equality operator ==.

It inherits from AbstractMatcher and defines its operator as :==.

Used for conditions like:

  • { age: { '$eq' => 30 } }
  • { name: "Alice" } (implicit fallback)

This matcher supports any Ruby object that implements #==.

Examples:

matcher = EqMatcher.build(42)
matcher.match?(42)       #=> true
matcher.match?("42")     #=> false

end

#raw_proc ⇒ Proc

Creates a raw Proc that performs the equality check. The Proc uses the == operator to compare values.

Returns:

  • (Proc) —
