For example, PKIX uses such notation in RFC 5912. With such notation (constraints on parameterized types using information object sets), generic ASN.1 tools/libraries can automatically encode/decode/resolve references within a document. ^ The primary format is binary, a json encoder is available. [10]
// comments are allowed in Ion files using the double forward slash {key: "value", // key here is a symbol, it can also be a string as in JSON nums: 1 _000_000, // equivalent to 1000000, use of underscores with numbers is more readable 'A float value': 31415e-4, // key is a value that contains spaces "An int value":. int, annotated: age:: 35, // age here is the annotation to number 35 lists ...
An exception to this are Microsoft's variant 2 UUIDs ("GUID"): historically used in COM/OLE libraries, they use a little-endian format, but appear mixed-endian with the first three components of the UUID as little-endian and last two big-endian, due to the missing byte dashes when formatted as a string. [23] For example, 00112233-4455-6677-8899 ...
Java provides an Instant object which holds a Unix timestamp in both seconds and nanoseconds. [22] Python provides a time library which uses Unix time. [ 23 ] JavaScript provides a Date library which provides and stores timestamps in milliseconds since the Unix epoch and is implemented in all modern desktop and mobile web browsers as well as in ...
However, indices can use any NumPy data type, including floating point, timestamps, or strings. [4]: 112 Pandas' syntax for mapping index values to relevant data is the same syntax Python uses to map dictionary keys to values. For example, if s is a Series, s['a'] will return the data point at index a. Unlike dictionary keys, index values are ...
String interning speeds up string comparisons, which are sometimes a performance bottleneck in applications (such as compilers and dynamic programming language runtimes) that rely heavily on associative arrays with string keys to look up the attributes and methods of an object. Without interning, comparing two distinct strings may involve ...
For function that manipulate strings, modern object-oriented languages, like C# and Java have immutable strings and return a copy (in newly allocated dynamic memory), while others, like C manipulate the original string unless the programmer copies data to a new string. See for example Concatenation below.
An Interoperable Object Reference (IOR) is a CORBA or RMI-IIOP reference that uniquely identifies an object on a remote CORBA server.. IORs can be transmitted in binary over TCP/IP via the General Inter-ORB Protocol (the encoding may be big-endian or little-endian), or serialized into a string of hexadecimal digits (prefixed by the string IOR:) to facilitate transport by non-CORBA mechanisms ...
