Implementations
The DataView
view provides a low-level interface for reading and
writing multiple number types in an ArrayBuffer
irrespective of the
platform’s endianness.
The ArrayBuffer referenced by this view. Fixed at construction time and thus read only.
The length (in bytes) of this view from the start of its ArrayBuffer. Fixed at construction time and thus read only.
The offset (in bytes) of this view from the start of its ArrayBuffer. Fixed at construction time and thus read only.
The getInt8()
method gets a signed 8-bit integer (byte) at the
specified byte offset from the start of the DataView.
The getUint8()
method gets a unsigned 8-bit integer (byte) at the specified
byte offset from the start of the DataView.

method gets a signed 16-bit integer (short) at the specified
byte offset from the start of the DataView.
The getInt16()
method gets a signed 16-bit integer (short) at the specified
byte offset from the start of the DataView.
The getUint16()
method gets an unsigned 16-bit integer (unsigned short) at the specified
byte offset from the start of the view.
The getUint16()
method gets an unsigned 16-bit integer (unsigned short) at the specified
byte offset from the start of the view.

method gets a signed 32-bit integer (long) at the specified
byte offset from the start of the DataView.
The getInt32()
method gets a signed 32-bit integer (long) at the specified
byte offset from the start of the DataView.
The getUint32()
method gets an unsigned 32-bit integer (unsigned long) at the specified
byte offset from the start of the view.
The getUint32()
method gets an unsigned 32-bit integer (unsigned long) at the specified
byte offset from the start of the view.
The getFloat32()
method gets a signed 32-bit float (float) at the specified
byte offset from the start of the DataView.
The getFloat32()
method gets a signed 32-bit float (float) at the specified
byte offset from the start of the DataView.
The getFloat64()
method gets a signed 64-bit float (double) at the specified
byte offset from the start of the DataView.
The getFloat64()
method gets a signed 64-bit float (double) at the specified
byte offset from the start of the DataView.
The setInt8()
method stores a signed 8-bit integer (byte) value at the
specified byte offset from the start of the DataView.
The setUint8()
method stores an unsigned 8-bit integer (byte) value at the
specified byte offset from the start of the DataView.
The setInt16()
method stores a signed 16-bit integer (short) value at the
specified byte offset from the start of the DataView.
The setInt16()
method stores a signed 16-bit integer (short) value at the
specified byte offset from the start of the DataView.
The setUint16()
method stores an unsigned 16-bit integer (unsigned short) value at the
specified byte offset from the start of the DataView.
The setUint16()
method stores an unsigned 16-bit integer (unsigned short) value at the
specified byte offset from the start of the DataView.
The setInt32()
method stores a signed 32-bit integer (long) value at the
specified byte offset from the start of the DataView.
The setInt32()
method stores a signed 32-bit integer (long) value at the
specified byte offset from the start of the DataView.
The setUint32()
method stores an unsigned 32-bit integer (unsigned long) value at the
specified byte offset from the start of the DataView.
The setUint32()
method stores an unsigned 32-bit integer (unsigned long) value at the
specified byte offset from the start of the DataView.
The setFloat32()
method stores a signed 32-bit float (float) value at the
specified byte offset from the start of the DataView.
The setFloat32()
method stores a signed 32-bit float (float) value at the
specified byte offset from the start of the DataView.
The setFloat64()
method stores a signed 64-bit float (double) value at the
specified byte offset from the start of the DataView.
The setFloat64()
method stores a signed 64-bit float (double) value at the
specified byte offset from the start of the DataView.
Methods from Deref<Target = Object>
The constructor property returns a reference to the Object
constructor
function that created the instance object.
The hasOwnProperty()
method returns a boolean indicating whether the
object has the specified property as its own property (as opposed to
inheriting it).
The isPrototypeOf()
method checks if an object exists in another
object’s prototype chain.
The propertyIsEnumerable()
method returns a Boolean indicating
whether the specified property is enumerable.
The toLocaleString()
method returns a string representing the object.
This method is meant to be overridden by derived objects for
locale-specific purposes.
The toString()
method returns a string representing the object.
The valueOf()
method returns the primitive value of the
specified object.
