This process of serializing an object is also called marshalling an object in some situations. Serialization of object-oriented objects does not include any of their associated methods with which they were previously linked. For many complex objects, such as those that make extensive use of references, this process is not straightforward. When the resulting series of bits is reread according to the serialization format, it can be used to create a semantically identical clone of the original object. data streams over computer networks) and reconstructed later (possibly in a different computer environment). files in secondary storage devices, data buffers in primary storage devices) or transmitted (e.g. In computing, serialization (or serialisation) is the process of translating a data structure or object state into a format that can be stored (e.g. For other uses, see Serialization (disambiguation). In rarer cases the OS or architecture must also match, for example when using packages that contain platform-dependent code.This article is about data structure encoding. In some cases, the word size (32- or 64-bit) of the reading and writing machines must match. Serializing anonymous functions should be avoided in files intended for long-term storage. Anonymous functions require special care: because their names are automatically generated, minor code changes can cause them to be renamed. ![]() Renaming functions, even private functions, inside packages can also put existing files out of sync. If that occurs, it may be necessary to specify an explicit compatible version of the affected package in your environment. The main exception to this is when the definition of a type in an external package changes. The data format can change in minor (1.x) Julia releases, but files written by prior 1.x versions will remain readable. ![]() To avoid writing the header, construct a Serializer and use it as the first argument to serialize instead. The read-back value will be as identical as possible to the original, but note that Ptr values are serialized as all-zero bit patterns ( NULL).Īn 8-byte identifying header is written to the stream first. Write an arbitrary value to a stream in an opaque format, such that it can be read back by deserialize.
