Description
DataView
instances inherit from DataView.prototype
. As with all constructors, you can change the constructor's prototype object to make changes to all DataView
instances.
Properties
DataView.prototype.constructor
- Specifies the function that creates an object's prototype. The initial value is the standard built-in
DataView
constructor. DataView.prototype.buffer
Read only- The
ArrayBuffer
referenced by this view. Fixed at construction time and thus read only. DataView.prototype.byteLength
Read only- The length (in bytes) of this view from the start of its
ArrayBuffer
. Fixed at construction time and thus read only. DataView.prototype.byteOffset
Read only- The offset (in bytes) of this view from the start of its
ArrayBuffer
. Fixed at construction time and thus read only.
Methods
Read
DataView.prototype.getInt8()
- Gets a signed 8-bit integer (byte) at the specified byte offset from the start of the view.
DataView.prototype.getUint8()
- Gets an unsigned 8-bit integer (unsigned byte) at the specified byte offset from the start of the view.
DataView.prototype.getInt16()
- Gets a signed 16-bit integer (short) at the specified byte offset from the start of the view.
DataView.prototype.getUint16()
- Gets an unsigned 16-bit integer (unsigned short) at the specified byte offset from the start of the view.
DataView.prototype.getInt32()
- Gets a signed 32-bit integer (long) at the specified byte offset from the start of the view.
DataView.prototype.getUint32()
- Gets an unsigned 32-bit integer (unsigned long) at the specified byte offset from the start of the view.
DataView.prototype.getFloat32()
- Gets a signed 32-bit float (float) at the specified byte offset from the start of the view.
DataView.prototype.getFloat64()
- Gets a signed 64-bit float (double) at the specified byte offset from the start of the view.
