Field Summary

Fields
Modifier and Type	Field and Description
`protected ArrayBufferImpl`	`arrayBuf`
`protected int`	`byteLength`
`protected int`	`byteOffset`
`(package private) static boolean`	`USE_LITTLE_ENDIAN` The spec lets the platform's native endianness come through, so we choose to expose little-endian regardless -- if apps care about the endianness but don't test for it, it is likely they assume little-endian.

Methods
Modifier and Type	Method and Description
`ArrayBuffer`	`buffer()` Get the underlying `ArrayBuffer`.

`int`	`byteOffset()` Get the offset from the beginning of the underlying `ArrayBuffer`.
`protected int`	`checkRange(int index, int bytesPerElement)` Check the index range and throw an exception if out of range, if ok return the byte index of the specified element.
