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).

Creates an array with given elements.

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.

Concatenates all arrays into a single array.

Copy one array to another. Equivalent to Java's System.arraycopy(src, srcPos, dest, destPos, length), except that this also works for polymorphic and boxed arrays.

Note that the passed-in dest array will be modified by this call.

Copy one array to another, truncating or padding with default values (if necessary) so the copy has the specified length. The new array can have a different type than the original one as long as the values are assignment-compatible. When copying between primitive and object arrays, boxing and unboxing are supported.

Equivalent to Java's java.util.Arrays.copyOf(original, newLength, newType), except that this works for all combinations of primitive and object arrays in a single method.

Copy one array to another, truncating or padding with default values (if necessary) so the copy has the specified length.

Equivalent to Java's java.util.Arrays.copyOf(original, newLength), except that this works for primitive and object arrays in a single method.

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).

The equality method for reference types. Default implementation delegates to eq.

See also equals in scala.Any.

Returns a five-dimensional array that contains the results of some element computation a number of times.

Returns a four-dimensional array that contains the results of some element computation a number of times.

Returns a three-dimensional array that contains the results of some element computation a number of times.

Returns a two-dimensional array that contains the results of some element computation a number of times.

Returns an array that contains the results of some element computation a number of times.

Note that this means that elem is computed a total of n times:

scala> Array.fill(3){ math.random }
res3: Array[Double] = Array(0.365461167592537, 1.550395944913685E-4, 0.7907242137333306)

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.

Returns the runtime class representation of the object.

The hashCode method for reference types. See hashCode in scala.Any.

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.

Returns an array containing repeated applications of a function to a start value.

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 an array containing equally spaced values in some integer interval.

Returns an array containing a sequence of increasing integers in a range.

Returns a five-dimensional array containing values of a given function over ranges of integer values starting from 0.

Returns a four-dimensional array containing values of a given function over ranges of integer values starting from 0.

Returns a three-dimensional array containing values of a given function over ranges of integer values starting from 0.

Returns a two-dimensional array containing values of a given function over ranges of integer values starting from 0.

Returns an array containing values of a given function over a range of integer values starting from 0.

Creates a String representation of this object. The default representation is platform dependent. On the java platform it is the concatenation of the class name, "@", and the object's hashcode in hexadecimal.

Called in a pattern match like { case Array(x,y,z) => println('3 elements')}.
