C++ serialize array of uint8

WebDec 16, 2008 · Ok - found it. The problem was not on the serialization but on the message creation/parsing. The buffer the C++ code was parsing the protocol buffer message from was not properly initialized causing the ByteSize() function to return an incorrect value based on the junk padded past the typical sentinel. I did a call to memset prior and all is good. WebEach JSON object has an overhead of one pointer (the maximal size of a union) and one enumeration element (1 byte). The default generalization uses the following C++ data types: std::string for strings, int64_t, uint64_t or double for numbers, std::map for objects, std::vector for arrays, and bool for Booleans.

Makes the assumption that your elements are relocate-able; i.e. that they can be transparently moved to new memory without a copy constructor. The main implication is that pointers to elements in the TArray may be invalidated by adding or removing other elements to the array.
