System

ported from java.lang.System, only contains things needed for lucenekmp

The {@code System} class contains several useful class fields and methods. It cannot be instantiated.

Among the facilities provided by the {@code System} class are standard input, standard output, and error output streams; access to externally defined properties and environment variables; a means of loading files and libraries; and a utility method for quickly copying a portion of an array.

Functions

arraycopy

@JvmName(name = "arraycopyKtNullable")

fun <T> arraycopy(src: Array<T?>, srcPos: Int, dest: Array<T?>, destPos: Int, length: Int)

ported from java.lang.System.arraycopy()

@JvmName(name = "arraycopyKt")

fun <T> arraycopy(src: Array<T>, srcPos: Int, dest: Array<T>, destPos: Int, length: Int)

fun arraycopy(src: Array<IntArray>, srcPos: Int, dest: Array<IntArray>, destPos: Int, length: Int)

fun arraycopy(src: BooleanArray, srcPos: Int, dest: BooleanArray, destPos: Int, length: Int)

fun arraycopy(src: ByteArray, srcPos: Int, dest: ByteArray, destPos: Int, length: Int)

fun arraycopy(src: CharArray, srcPos: Int, dest: CharArray, destPos: Int, length: Int)

fun arraycopy(src: FloatArray, srcPos: Int, dest: FloatArray, destPos: Int, length: Int)

fun arraycopy(src: IntArray, srcPos: Int, dest: IntArray, destPos: Int, length: Int)

fun arraycopy(src: LongArray, srcPos: Int, dest: LongArray, destPos: Int, length: Int)

currentTimeMillis

fun currentTimeMillis(): Long

getProperty

fun getProperty(key: String, def: String? = null): String?

ported from java.lang.System.getProperty() but implementation is EnvVar

lineSeparator

fun lineSeparator(): String

for now target platform only includes JVM (server which means linux server), Android, and iOS all of them use "\n" as the line separator. this implementation will cause problem only on running this program in kotlin/JVM on Windows, or kotlin/Native on Windows.

nanoTime

fun nanoTime(): Long
