Value members

Concrete methods

Tests whether the argument (that) is a reference to the receiver object (this).

Tests whether the argument (that) is a reference to the receiver object (this).

The eq method implements an equivalence relation on non-null instances of AnyRef, and has three additional properties:

It is consistent: for any non-null instances x and y of type AnyRef, multiple invocations of x.eq(y) consistently returns true or consistently returns false.
For any non-null instance x of type AnyRef, x.eq(null) and null.eq(x) returns false.
null.eq(null) returns true.

When overriding the equals or hashCode methods, it is important to ensure that their behavior is consistent with reference equality. Therefore, if two objects are references to each other (o1 eq o2), they should be equal to each other (o1 == o2) and they should hash to the same value (o1.hashCode == o2.hashCode).

Value parameters:

that: the object to compare against this object for reference equality.

Returns:

true if the argument is a reference to the receiver object; false otherwise.

Equivalent to !(this eq that).

Equivalent to !(this eq that).

Value parameters:

that: the object to compare against this object for reference equality.

Returns:

true if the argument is not a reference to the receiver object; false otherwise.

Wakes up a single thread that is waiting on the receiver object's monitor.
