Constructor Details

Int16Array()

• Int16Array()
  • : Creates an empty array.

Int16Array(Number)

• Int16Array(length: Number)

  • : Creates an array with the given element count.

    Parameters:

    • length - The number of elements.

Int16Array(Object)

• Int16Array(typedArray: Object)

  • : Creates an array as a copy of the passed typed array.

    Parameters:

    • typedArray - The source typed array.

Int16Array(Array)

• Int16Array(array: Array)

  • : Creates an array as a copy of the passed array.

    Parameters:

    • array - The source array.

Int16Array(ArrayBuffer, Number, Number)

• Int16Array(buffer: ArrayBuffer, byteOffset: Number, length: Number)

  • : Creates a typed array as a view on the given ArrayBuffer.

    Parameters:

    • buffer - The array buffer storage object.
    • byteOffset - Optional. The offset within the array buffer in bytes.
    • length - Optional. The number of elements for the target typed array. The passed array buffer must be large enough to store the number of elements specified.

Method Details

get(Number)

• get(index: Number): Number

  • : Returns the value at the specified index.

    Note: This is not ECMAScript standard. Use array element access syntax for single value access.

    Parameters:

    • index - The index to use.

    Returns:

    • The value at the specified index.

set(Object, Number)

• set(values: Object, offset: Number): void

  • : Copies all values from the source array into this typed array.

    Parameters:

    • values - The source values. Can be an array or a typed array.
    • offset - Optional. Target offset.

subarray(Number, Number)

• subarray(begin: Number, end: Number): Int16Array

  • : Returns a new array object based on the same ArrayBuffer store.

    Parameters:

    • begin - Optional. The first included element.
    • end - Optional. The index of the end. This element is not included.

    Returns:

    • The new array object.
