equals

kotlin-stdlib / kotlin / Enum / equals
 

Platform and version requirements: JVM (1.0), JS (1.1), Native (1.3) fun equals(other: Any?): Boolean 
 Indicates whether some other object is "equal to" this one. Implementations must fulfil the following requirements: 
Reflexive: for any non-null value x, x.equals(x) should return true. Symmetric: for any non-null values x and y, x.equals(y) should return true if and only if y.equals(x) returns true. Transitive: for any non-null values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true. Consistent: for any non-null values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified. Never equal to null: for any non-null value x, x.equals(null) should return false.  Read more about equality in Kotlin.
