Upgrade Compatibility of Boost Serialization with binary archives armv7 to arm64
c++,serialization,boost,boost-serialization,arm64
If you need to keep user's data you're gonna have to reverse engineer your way out of hell. You could maybe cheat by having the old data sent to a server for transformation. For portable archives you can try the OES Portable Archive implementation. It is supposed to be a...
POJOs to byte array vs POJOs to json
Serialize data means convert them to a sequence of bytes. This sequence can be interpreted as a sequence of readable chars as happens in json, xml, yaml and so on. The same sequence can be also a sequence of binary data that is not human readable. There are pro and...
Value Object vs Data Transfer Object
java,design-patterns,serialization,domain-driven-design,data-transfer-objects
Objects are made Serializable to be able to be transferred. It allows to convert Object to bytes and then bytes to Object. Note that usually DTO are made lighter (since travelling to client) than your Domain Objects that usually have a lot of attributes made for Business processing only. So...
Serialize/Deserialize class containing byte array property into XML
c#,.net,xml,serialization,.net-4.0
As you've noticed, there are lots of characters that may not be present in an XML document. These can be included in your data, however, using the proper escape sequence. The default settings of the XmlTextReader cause it to mishandle this -- I think it interprets the escape sequences prematurely,...

Partial deserialization of a huge binary file - Java
Forget using the Java serialization API - it's only designed to deserialize everything. If you have no control over how the serialized file is generated, then you should consider parsing the serialized file yourself and extracting the necessary parts - it's not really that hard. The Java serialization format is...

Gson not deserializing JSON data
Your JSON (which you get from Yahoo) is very complex. So it can not be easily mapped to simple POJO (but you still can write huge POJO that contains fields for all corresponding nested JSON elements). But it is possible to parse and extract specific elements from JSON. The code:...
Jackson How to retrieve parent bean in a custom Serializer/Deserializer
java,json,serialization,jackson
If you are using Jackson 2.5, it is possible to access parent object via JsonGenerator.getCurrentValue(). Or, further up the hierarchy, going via getOutputContext() (which has getParent() as well as getCurrentValue() method). This is also available through JsonParser for custom deserializer.

Why serialization is not required for InProc session mode
c#,asp.net,asp.net-mvc,session,serialization
Using InProc sessions, the data is not "stored" anywhere, it just stays in memory. This way no serialization is needed. For the other methods the data does need to be written to somewhere (state server, sql server) and needs to be converted to a stream of bytes (and back again)....

Your file isn't a valid XML file. According to the W3C website, node identifiers cannot start with digits.

JSON parsing using .NET deserialize() with nested “list”
javascript,c#,json,parsing,serialization
One possibility is to deserialize into a dynamic object and convert from that to your strongly-typed object. Like so: var dict = new JavaScriptSerializer().Deserialize<dynamic>(responseText); The resulting dict object is a dictionary, with each property represented as a name-value pair in the dictionary. Nested objects, such as roster and its contained...

FileSystemInfo isn't serializable, because it is not a simple type. FileInfo isn't serializable, because it has no empty default constructor.

Will the type information be preserved here? Yes; for example, this: final ParameterizedType superTypeOfPersons = (ParameterizedType) Persons.class.getGenericSuperclass(); System.out.println(superTypeOfPersons.getActualTypeArguments()[0].getSimpleName()); will print Person.
