template <typename T, size_t min_align = 1>class ExplicitlyConstructed
Defined at line 38 of file ../../third_party/protobuf/src/google/protobuf/explicitly_constructed.h
Wraps a variable whose constructor and destructor are explicitly
called. It is particularly useful for a global variable, without its
constructor and destructor run on start and end of the program lifetime.
This circumvents the initial construction order fiasco, while keeping
the address of the empty string a compile time constant.
Pay special attention to the initialization state of the object.
1. The object is "uninitialized" to begin with.
2. Call Construct() or DefaultConstruct() only if the object is
uninitialized. After the call, the object becomes "initialized".
3. Call get() and get_mutable() only if the object is initialized.
4. Call Destruct() only if the object is initialized.
After the call, the object becomes uninitialized.
