to compare instances of this class.

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. |
hashCode
open fun hashCode(): Int
Return |
Int |
a hash code value for this object. |
