| Method | Modifiers | Description |
|---|---|---|
| castToBaseType() | Although the typed array tuples extend a typed array, they are not structurally compatible. This function returns the argument passed without modification but cast as the underlying storage type, e.g. Float32Array. | |
| copyFromBuffer(_memoryDataView, _pointer, _littleEndian) | If endianness is not supplied the platform’s endianness will be used. | |
| copyToBuffer(_memoryDataView, _pointer, _littleEndian) | If endianness is not supplied the platform’s endianness will be used. | |
