1.  final def !=(arg0: Any): Boolean

   Test two objects for inequality.

   Test two objects for inequality.

   returns

   true if !(this == that), false otherwise.

   Definition Classes

   AnyRef → Any

2.  final def ##(): Int

   Equivalent to x.hashCode except for boxed numeric types and null.

   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.

   returns

   a hash value consistent with ==

3.  final def ==(arg0: Any): Boolean

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

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

   returns

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

4.  val EOL: String

   The default line separator.

   The default line separator.

   On the JVM, this is equivalent to calling the method: java.lang.System.lineSeparator

5.  def arrayclear(arr: Array[Int]): Unit

   Assigns the value of 0 to each element in the array.

   Assigns the value of 0 to each element in the array.

   arr

   A non-null Array[Int].

   Annotations

   @inline()

   Exceptions thrown

   java.lang.NullPointerException If arr is null.

6.  def arraycopy(src: AnyRef, srcPos: Int, dest: AnyRef, destPos: Int, length: Int): Unit

   Copies length elements of array src starting at position srcPos to the array dest starting at position destPos.

   Copies length elements of array src starting at position srcPos to the array dest starting at position destPos. If src==dest, the copying will behave as if the elements copied from src were first copied to a temporary array before being copied back into the array at the destination positions.

   src

   A non-null array as source for the copy.

   srcPos

   The starting index in the source array.

   dest

   A non-null array as destination for the copy.

   destPos

   The starting index in the destination array.

   length

   The number of elements to be copied.

   Annotations

   @inline()

   Exceptions thrown

   java.lang.ArrayStoreException If either src or dest are not of type [java.lang.Array]; or if the element type of src is not compatible with that of dest.

   java.lang.IndexOutOfBoundsException If either srcPos or destPos are outside of the bounds of their respective arrays; or if length is negative; or if there are less than length elements available after srcPos or destPos in src and dest respectively.

   java.lang.NullPointerException If either src or dest are null.

7.  final def asInstanceOf[T0]: T0

   Cast the receiver object to be of type T0.

   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.

   returns

   the receiver object.

   Definition Classes

   Any

   Exceptions thrown

   ClassCastException if the receiver object is not an instance of the erasure of type T0.

8.  def clone(): AnyRef

   The default implementation of the clone method is platform dependent.

9.  def collectGarbage(): Unit

   Runs the garbage collector.

   Runs the garbage collector.

   This is a request that the underlying JVM runs the garbage collector. The results of this call depends heavily on the JVM used. The underlying JVM is free to ignore this request.

10.  def createArray(elemClass: Class[_], length: Int): AnyRef

    Creates a new array of the specified type and given length.

    Creates a new array of the specified type and given length.

    Note that if elemClass is a subclass of scala.AnyVal then the returned value is an Array of the corresponding java primitive type. For example, the following code scala.compat.Platform.createArray(classOf[Int], 4) returns an array of the java primitive type int.

    For a scala.AnyVal array, the values of the array are set to 0 for numeric value types (scala.Double, scala.Float, scala.Long, scala.Int, scala.Char, scala.Short, and scala.Byte), and false for scala.Boolean. Creation of an array of type scala.Unit is not possible.

    For subclasses of scala.AnyRef, the values of the array are set to null.

    The caller must cast the returned value to the correct type.

    elemClass

    the Class object of the component type of the array

    length

    the length of the new array.

    returns

    an array of the given component type as an AnyRef.

    Example:

    1. val a = scala.compat.Platform.createArray(classOf[Int], 4).asInstanceOf[Array[Int]] // returns Array[Int](0, 0, 0, 0)

    Exceptions thrown

    java.lang.IllegalArgumentException if componentType is scala.Unit or java.lang.Void.TYPE

    java.lang.NegativeArraySizeException if the specified length is negative

    java.lang.NullPointerException If elemClass is null.

11.  def currentTime: Long

    The current time in milliseconds.

13.  final def eq(arg0: AnyRef): Boolean

    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).

    returns

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

14.  def equals(arg0: Any): Boolean

15.  def finalize(): Unit

    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.

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

    Note that the result of the test is modulo Scala's erasure semantics.
