Public methods
equals
open fun equals(other: Any?): Boolean
Indicates whether some other object is "equal to" this one.
The equals method implements an equivalence relation on non-null object references:
- It is reflexive: for any non-null reference value
x, x.equals(x) should return true.
- It is symmetric: for any non-null reference values
x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
- It is transitive: for any non-null reference values
x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
- It is consistent: for any non-null reference 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.
- For any non-null reference value
x, x.equals(null) should return false.
An equivalence relation partitions the elements it operates on into equivalence classes; all the members of an equivalence class are equal to each other. Members of an equivalence class are substitutable for each other, at least for some purposes.
| Parameters |
obj |
the reference object with which to compare. |
o |
This value may be null. |
| Return |
Boolean |
true if this object is the same as the obj argument; false otherwise. |

| Return |
String |
a string consisting of exactly this sequence of characters |
Properties
