Return values from Buffer
info: |
24.2.4.11 DataView.prototype.getUint16 ( byteOffset [ , littleEndian ] )
1. Let v be the this value.
2. If littleEndian is not present, let littleEndian be false.
3. Return ? GetViewValue(v, byteOffset, littleEndian, "Uint16").
24.2.1.1 GetViewValue ( view, requestIndex, isLittleEndian, type )
...
14. Let bufferIndex be getIndex + viewOffset.
15. Return GetValueFromBuffer(buffer, bufferIndex, type, isLittleEndian).
...
24.1.1.5 GetValueFromBuffer ( arrayBuffer, byteIndex, type [ , isLittleEndian
] )
...
8. If isLittleEndian is false, reverse the order of the elements of rawValue.
