Test two objects for inequality.

Equivalent to x.hashCode except for boxed numeric types and null. For numerics, it returns a hash value which is consistent with value equality: if two value type instances compare as true, then ## will produce the same hash value for each of them. For null returns a hashcode where null.hashCode throws a NullPointerException.

The expression x == that is equivalent to if (x eq null) that eq null else x.equals(that).

Cast the receiver object to be of type T0.

Note that the success of a cast at runtime is modulo Scala's erasure semantics. Therefore the expression 1.asInstanceOf[String] will throw a ClassCastException at runtime, while the expression List(1).asInstanceOf[List[String]] will not. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the requested type.

Create a copy of the receiver object.

The default implementation of the clone method is platform dependent.

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).

Returns false if Left or returns the result of the application of the given function to the Right value.

Right(12).right.exists(_ > 10)  // true
Right(7).right.exists(_ > 10)   // false
Left(12).right.exists(_ > 10)   // false

Returns None if this is a Left or if the given predicate p does not hold for the right value, otherwise, returns a Right.

Right(12).right.filter(_ > 10) // Some(Right(12))
Right(7).right.filter(_ > 10)  // None
Left(12).right.filter(_ > 10)  // None

Called by the garbage collector on the receiver object when there are no more references to the object.

The details of when and if the finalize method is invoked, as well as the interaction between finalize and non-local returns and exceptions, are all platform dependent.

Binds the given function across Right.

Returns true if Left or returns the result of the application of the given function to the Right value.

Right(12).right.forall(_ > 10) // true
Right(7).right.forall(_ > 10)  // false
Left(12).right.forall(_ > 10)  // true

Executes the given side-effecting function if this is a Right.

Right(12).right.foreach(x => println(x)) // prints "12"
Left(12).right.foreach(x => println(x))  // doesn't print

Returns string formatted according to given format string. Format strings are as for String.format (@see java.lang.String.format).

Returns the value from this Right or throws java.util.NoSuchElementException if this is a Left.

Right(12).right.get // 12
Left(12).right.get // NoSuchElementException

Returns the runtime class representation of the object.

Returns the value from this Right or the given argument if this is a Left.

Right(12).right.getOrElse(17) // 12
Left(12).right.getOrElse(17)  // 17

Test whether the dynamic type of the receiver object is T0.

Note that the result of the test is modulo Scala's erasure semantics. Therefore the expression 1.isInstanceOf[String] will return false, while the expression List(1).isInstanceOf[List[String]] will return true. In the latter example, because the type argument is erased as part of compilation it is not possible to check whether the contents of the list are of the specified type.

The given function is applied if this is a Right.

Right(12).right.map(x => "flower") // Result: Right("flower")
Left(12).right.map(x => "flower")  // Result: Left(12)

Equivalent to !(this eq that).

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

Wakes up all threads that are waiting on the receiver object's monitor.

Returns a Some containing the Right value if it exists or a None if this is a Left.

Right(12).right.toOption // Some(12)
Left(12).right.toOption // None

Returns a Seq containing the Right value if it exists or an empty Seq if this is a Left.

Right(12).right.toSeq // Seq(12)
Left(12).right.toSeq // Seq()
