Detailed Description
Serializes objects that derive from SavableState.
StateOut keeps track of pointers to data so that two references to the same piece of data do not result in that data being sent to the output device two times.
Member Function Documentation
◆ copy_references()
| void sc::StateOut::copy_references | ( | ) |
If a reference to an object that has already been written is encountered, copy it instead of generating a reference to the first object.
The directory will not be updated with new objects.
◆ forget_references()
| void sc::StateOut::forget_references | ( | ) |
Don't keep track of pointers to objects.
Calling this causes duplicated references to objects to be copied. The directory will not contain the forgotten objects.
◆ node_to_node()
|
inline |
True if this is a node to node save/restore.
This is necessary for classes that try to avoid saving databases to files that can otherwise be read in, but want to avoid reading the database from disk on all nodes.
◆ put()
|
virtual |
Write the given array data.
Size information is also saved. The data is allocated and read by the get(T*&) routines.
Reimplemented in sc::MsgStateSend, and sc::StateOutText.
◆ put_array_char()
|
virtual |
Put arrays of data.
No size information is stored. This data is read by the get_array_T routines.
Reimplemented in sc::StateOutText.
◆ putobject()
|
protectedvirtual |
This will prepare StateOut to output a pointer to data.
It first checks to see if the data has already been saved. If it has, then a reference to this data is saved. Otherwise the object is written out.
Reimplemented in sc::StateOutText.
◆ seek()
|
virtual |
Set the current position in the file.
The default implementation does nothing.
Reimplemented in sc::StateOutBin.
◆ seekable()
|
virtual |
Return non-zero if tell and seek do anything sensible.
The default implementation returns 0.
Reimplemented in sc::StateOutBin.
◆ tell()
|
virtual |
Returns the current position in the file.
The default implementation returns 0.
Reimplemented in sc::StateOutBin.
