## Class NativeArrayBufferView

- java.lang.Object
- - org.mozilla.javascript.ScriptableObject
  - - org.mozilla.javascript.IdScriptableObject
    - - org.mozilla.javascript.typedarrays.NativeArrayBufferView

- All Implemented Interfaces:
    `java.io.Serializable`, `ConstProperties`, `DebuggableObject`, `IdFunctionCall`, `Scriptable`, `SymbolScriptable`
  Direct Known Subclasses:
    `NativeDataView`, `NativeTypedArrayView`

      public abstract class NativeArrayBufferView
      extends IdScriptableObject

  This class is the abstract parent for all views of the array. It shows a view of the underlying NativeArrayBuffer. Many views may simultaneously share the same buffer, and changes to one will affect all.

      Return the buffer that backs this view.

    - #### getByteOffset

          public int getByteOffset()

      Return the offset in bytes from the start of the buffer that this view represents.

    - #### getByteLength

          public int getByteLength()
