Interface Float64Array

All Superinterfaces:

ArrayBufferView, IndexableNumber

All Known Implementing Classes:

JsFloat64Array

public interface Float64Array
extends ArrayBufferView, IndexableNumber

The Float64Array type represents an array of 64-bit floating point numbers (corresponding to the C double data type).

Once established, you can reference elements in the array using the object's methods, or using standard array index syntax (that is, using bracket notation).

Field Summary

Fields

Modifier and Type	Field and Description
static int	BYTES_PER_ELEMENT The size, in bytes, of each array element.

Methods

Modifier and Type	Method and Description
int	getLength() The number of entries in the array.
void	setElements(Object array)
void	setElements(Object array, int offset)
Float64Array	subarray(int start) Returns a new Float64Array view on the ArrayBuffer store for this Float64Array object.
Float64Array	subarray(int start, int end) Returns a new Float64Array view on the ArrayBuffer store for this Float64Array object.

static final int BYTES_PER_ELEMENT

Constant Field Values

Method Detail

getLength

int getLength()

The number of entries in the array. Read only.

setElements

void setElements(Object array)

setElements

void setElements(Object array,
               int offset)

subarray

Float64Array subarray(int start)

Returns a new Float64Array view on the ArrayBuffer store for this Float64Array object.

Parameters

begin

The offset to the first element in the array to be referenced by the new Float64Array object.

end Optional

The offset to the last element in the array to be referenced by the new Float64Array object; if not specified, all elements from the one specified by begin to the end of the array are included in the new view.

Notes

The range specified by begin and end is clamped to the valid index range for the current array; if the computed length of the new array would be negative, it's clamped to zero. If either begin or end is negative, it refers to an index from the end of the array instead of from the beginning.

Note: Keep in mind that this is creating a new view on the existing buffer; changes to the new object's contents will impact the original object and vice versa.

subarray

Float64Array subarray(int start,
                    int end)

Returns a new Float64Array view on the ArrayBuffer store for this Float64Array object.

Parameters

begin

The offset to the first element in the array to be referenced by the new Float64Array object.

end Optional

The offset to the last element in the array to be referenced by the new Float64Array object; if not specified, all elements from the one specified by begin to the end of the array are included in the new view.

Notes

The range specified by begin and end is clamped to the valid index range for the current array; if the computed length of the new array would be negative, it's clamped to zero. If either begin or end is negative, it refers to an index from the end of the array instead of from the beginning.
