Array.scala

Copy one array to another.

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.

dest

destination array.

destPos

starting position in the destination array.

length

the number of array elements to be copied.

src

the source array.

srcPos

starting position in the source array.

Array.scala

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

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.

Array.scala

Compare two arrays per element.

Compare two arrays per element.

A more efficient version of xs.sameElements(ys).

Note that arrays are invariant in Scala, but it may be sound to cast an array of arbitrary reference type to Array[AnyRef]. Arrays on the JVM are covariant in their element type.

Array.equals(xs.asInstanceOf[Array[AnyRef]], ys.asInstanceOf[Array[AnyRef]])

xs

an array of AnyRef

ys

an array of AnyRef

Returns

true if corresponding elements are equal

Source

Array.scala

Returns an 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.

res3: Array[Double] = Array(0.365461167592537, 1.550395944913685E-4, 0.7907242137333306)

the element computation

n

the number of elements desired

Returns

an Array of size n, where each element contains the result of computing elem.
