@deprecated("Use `java.util.ConcurrentModificationException` instead.", since = "2.13.0")

This is a type alias for java.util.ConcurrentModificationException, which may be thrown by methods that detect an invalid modification of an object.

This is a type alias for java.util.ConcurrentModificationException, which may be thrown by methods that detect an invalid modification of an object. For example, many common collection types do not allow modifying a collection while it is being iterated over.

@deprecated("Use `java.lang.StackOverflowError` instead.", since = "2.13.0")

Thrown when a stack overflow occurs because a method or function recurses too deeply.

Thrown when a stack overflow occurs because a method or function recurses too deeply.

On the JVM, this is a type alias for java.lang.StackOverflowError, which itself extends java.lang.Error. The same rules apply to catching a java.lang.Error as for Java, that it indicates a serious problem that a reasonable application should not try and catch.

@inline @deprecated("Use `java.util.Arrays#fill` instead.", since = "2.13.0")
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.

Value Params
arr

A non-null Array[Int].

Throws
java.lang.NullPointerException

If arr is null.

@inline @deprecated("Use `java.lang.System#arraycopy` instead.", since = "2.13.0")
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.

Value Params
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.

src

A non-null array as source for the copy.

srcPos

The starting index in the source array.

Throws
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.

@inline @deprecated("Use `java.lang.System#gc` instead.", since = "2.13.0")

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.

@inline @deprecated("Use `java.lang.reflect.Array#newInstance` instead.", since = "2.13.0")
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.

Value Params
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.

Throws
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.

Example

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

@inline @deprecated("Use `java.lang.Class#forName` instead.", since = "2.13.0")

Returns the Class object associated with the class or interface with the given string name using the current ClassLoader.

Returns the Class object associated with the class or interface with the given string name using the current ClassLoader. On the JVM, invoking this method is equivalent to: java.lang.Class.forName(name)

For more information, please see the Java documentation for java.lang.Class.

Value Params
name

the fully qualified name of the desired class.

Returns

the Class object for the class with the specified name.

Throws
java.lang.ClassNotFoundException

if the class cannot be located

java.lang.ExceptionInInitializerError

if the initialization provoked by this method fails

java.lang.LinkageError

if the linkage fails

Example

val a = scala.compat.Platform.getClassForName("java.lang.Integer")  // returns the Class[_] for java.lang.Integer
