This function takes into account ndarray-like objects which may support index modes.\n*\n* - This function defaults to returning cached serialized meta data.

If the endianness is `0`, the byte order is big endian.\n*\n* - Buffer length:\n*\n* ```text\n* 1 + 2 + 8 + (ndims*8) + (ndims*8) + 8 + 1 + 1 + 8 + (nsubmodes*1) + 4 = 33 + (ndims*16) + nsubmodes\n* ```\n*\n* For example, consider a three-dimensional ndarray with one subscript index mode (submode):\n*\n* ```text\n* 33 + (3*16) + 1 = 82 bytes\n* ```\n*\n* - Views:\n*\n* - endianness: `Int8Array(

This function is intended as a potential performance optimization. In V8, for example, even if two objects share common properties, if those properties were added in different orders or if one object has additional properties not shared by the other object, then those objects will have different \"hidden\" classes. If a function is provided many objects having different \"shapes\", some JavaScript VMs (e.g., V8) will consider the function \"megamorphic\" and fail to perform various runtime optimizations. Accordingly, the intent of this function is to standardize the \"shape\" of the object holding array meta data to ensure that internal functions operating on arrays are provided consistent argument \"shapes\".\n*\n* - The returned object has the following properties:\n*\n* - **data**: reference to the input array.\n* - **dtype**: array data type.\n* - **accessorProtocol**: `boolean` indicating whether the input array uses accessors for getting and setting elements.\n* - **accessors**: a two-element array whose first element is an accessor for retrieving an array element and whose second element is an accessor for setting an array element.\n*\n* @param {Collection} x -

This function takes into account ndarray-like objects which may support index modes.\n*\n* - This function defaults to returning cached serialized meta data. To force serialization, set the private `__meta_dataview__` property to `null`.\n*\n* - Serialization is performed according to host byte order (endianness).\n*\n* - Meta data format:\n*\n* ```text\n* | endianness (1 byte) | (2 bytes) | (8 bytes) | (ndims*8 bytes) | (ndims*8 bytes) | (8 bytes) | (1 byte) | (1 byte) | (8 bytes) | (nsubmodes*1 bytes) | (4 bytes) |\n* ```\n*\n* which translates to the following `ArrayBuffer` layout:\n*\n* ```text\n* ArrayBuffer[\n* [int8],\n* [int16],\n* [int64],\n* [ndims*int64],\n* [ndims*int64],\n* [int64],\n* [int8],\n* [int8],\n* [int64],\n* [nsubmodes*int8],\n* [int32]\n* ]\n* ```\n*\n* where `strides` and `offset` are in units of bytes.\n*\n* - If the endianness is `1`, the byte order is little endian. If the endianness is `0`, the byte order is big endian.\n*\n* - Buffer length:\n*\n* ```text\n* 1 + 2 + 8 + (ndims*8) + (ndims*8) + 8 + 1 + 1 + 8 + (nsubmodes*1) + 4 = 33 + (ndims*16) + nsubmodes\n* ```\n*\n* For example, consider a three-dimensional ndarray with one subscript index mode (submode):\n*\n* ```text\n* 33 + (3*16) + 1 = 82 bytes\n* ```\n*\n* - Views:\n*\n* - endianness: `Int8Array(

This function is intended as a potential performance optimization. In V8, for example, even if two objects share common properties, if those properties were added in different orders or if one object has additional properties not shared by the other object, then those objects will have different \"hidden\" classes. If a function is provided many objects having different \"shapes\", some JavaScript VMs (e.g., V8) will consider the function \"megamorphic\" and fail to perform various runtime optimizations. Accordingly, the intent of this function is to standardize the \"shape\" of the object holding array meta data to ensure that internal functions operating on arrays are provided consistent argument \"shapes\".\n*\n* - The returned object has the following properties:\n*\n* - **data**: reference to the input array.\n* - **dtype**: array data type.\n* - **accessorProtocol**: `boolean` indicating whether the input array uses accessors for getting and setting elements.\n* - **accessors**: a two-element array whose first element is an accessor for retrieving an array element and whose second element is an accessor for setting an array element.\n*\n* @param {Collection} x -
