# DataView

An interface for working with a raw binary buffer.

The DataView API is exactly as in JavaScript (MDN(opens new window) ).

# Constructor

  • new DataView(buffer: ArrayBuffer, byteOffset?: i32, byteLength?: i32)
    
    Constructs a new DataView on the specified buffer and region.

# Instance members

# Fields

  • readonly buffer: ArrayBuffer
    

    The backing buffer.

  • readonly byteLength: i32
    

    The length of this view from the start of its buffer.

  • readonly byteOffset: i32
    

    The offset of this view from the start of its buffer.

# Methods

  • function getFloat32(byteOffset: i32, littleEndian?: bool): f32
    

    Gets the 32-bit float value at the specified offset from the start of the view.

  • function getFloat64(byteOffset: i32, littleEndian?: bool): f64
    

    Gets the 64-bit float value at the specified offset from the start of the view.

  • function getInt8(byteOffset: i32): i8
    

    Gets the signed 8-bit integer value at the specified offset from the start of the view.

  • function getInt16(byteOffset: i32, littleEndian?: bool): i16

    Gets the signed 32-bit integer value at the specified offset from the start of the view.

  • function getInt64(byteOffset: i32, littleEndian?: bool): i64
    

    Gets the signed 64-bit integer value at the specified offset from the start of the view.

  • function getUint8(byteOffset: i32, littleEndian?: bool): u8
    

    Gets the unsigned 8-bit integer value at the specified offset from the start of the view.

  • function getUint16(byteOffset: i32, littleEndian?: bool): u16
    

    Gets the unsigned 16-bit integer value at the specified offset from the start of the view.

  • function getUint32(byteOffset: i32, littleEndian?: bool): u32
    

    Gets the unsigned 32-bit integer value at the specified offset from the start of the view.

  • function getUint64(byteOffset: i32, littleEndian?: bool): u64
    

    Gets the unsigned 64-bit integer value at the specified offset from the start of the view.

  • function setFloat32(byteOffset: i32, value: f32, littleEndian?: bool): void
    

    Sets the 32-bit float value at the specified offset from the start of the view.

  • function setFloat64(byteOffset: i32, value: f64, littleEndian?: bool): void
    

    Sets the 64-bit float value at the specified offset from the start of the view.

  • function setInt8(byteOffset: i32, value: i8): void
    

    Sets the signed 8-bit integer value at the specified offset from the start of the view.

  • function setInt16(byteOffset: i32, value: i16, littleEndian?: bool): void

  • function setInt32(byteOffset: i32, value: i32, littleEndian?: bool): void
    

    Sets the signed 32-bit integer value at the specified offset from the start of the view.

  • function setInt64(byteOffset: i32, value: i64, littleEndian?: bool): void
    

    Sets the signed 64-bit integer value at the specified offset from the start of the view.

  • function setUint8(byteOffset: i32, value: u8, littleEndian?: bool): void
    

    Sets the unsigned 8-bit integer value at the specified offset from the start of the view.

  • function setUint16(byteOffset: i32, value: u16, littleEndian?: bool): void
    

    Sets the unsigned 16-bit integer value at the specified offset from the start of the view.

  • function setUint32(byteOffset: i32, value: u32, littleEndian?: bool): void
    

    Sets the unsigned 32-bit integer value at the specified offset from the start of the view.

  • function setUint64(byteOffset: i32, value: u64, littleEndian?: bool): void
    

    Sets the unsigned 64-bit integer value at the specified offset from the start of the view.

  • function toString(): string
    

    Returns a string representation of this object.

Endianness defaults to littleEndian = false.
