class util::IntArray

sys::Obj
  util::IntArray

Source

Optimized fixed size array of 1, 2, 4, or 8 byte unboxed integers. The array values default to zero.

copyFrom

This copyFrom(IntArray that, Range? thatRange := null, Int thisOffset := 0)

Source

Copy the integers from that array into this array and return this. The thatRange parameter may be used to specify a specific range of integers from the that parameter (negative indices are allowed) to copy. If thatRange is null then the entire range of that is copied. Or thisOffset specifies the starting index of this index to copy the first integer. Raise an exception if this array is not properly sized or is not of the same signed/byte count as the that array.

fill

This fill(Int val, Range? range := null)

Source

Fill this array with the given integer value. If range is null then the entire array is filled, otherwise just the specified range. Return this.

get

@Operator
Int get(Int index)

Source

Get the integer at the given index. Negative indices are not supported.

makeS1

const static IntArray makeS1(Int size)

Source

Create a signed 8-bit, 1-byte integer array (-128 to 127).

makeS2

const static IntArray makeS2(Int size)

Source

Create a signed 16-bit, 2-byte integer array (-32_768 to 32_767).

makeS4

const static IntArray makeS4(Int size)

Source

Create a signed 32-bit, 4-byte integer array (-2_147_483_648 to 2_147_483_647).

makeS8

const static IntArray makeS8(Int size)

Source

Create a signed 64-bit, 8-byte integer array.

makeU1

const static IntArray makeU1(Int size)

Source

Create a unsigned 8-bit, 1-byte integer array (0 to 255).

makeU2

const static IntArray makeU2(Int size)

Source

Create a unsigned 16-bit, 2-byte integer array (0 to 65_535).

makeU4

const static IntArray makeU4(Int size)

Source

Create a unsigned 32-bit, 4-byte integer array (0 to 4_294_967_295).

set

@Operator
Void set(Int index, Int val)

Source

Set the integer at the given index. Negative indices are not supported.

size

Int size()

Source

Get number of integers in the array

sort

This sort(Range? range := null)

Source

Sort the integers in this array. If range is null then the entire array is sorted, otherwise just the specified range. Return this.
