Method: Weak::Map#has_value?

Defined in:
lib/weak/map.rb

#has_value?(value) ⇒ Bool Also known as: value?

Note:

Weak::Map does not test member equality with == or eql?. Instead, it always checks strict object equality, so that, e.g., different String keys are not considered equal, even if they may contain the same content.

Returns true if value is a value in self, false otherwise.

Parameters:

  • value (Object) —

    a value to check

Returns:

  • (Bool) —

    true if value is a value in self, false otherwise
