sc::StateIn - Restores objects that derive from SavableState.
#include <statein.h>
Inherits sc::DescribedClass.
Inherited by sc::MsgStateBufRecv, and sc::StateInFile.
virtual void get_header ()
Read in the header information. virtual int version (const
ClassDesc *)
Returns the version of the ClassDesc in the persistent object or -1 if
info on the ClassDesc doesn't exist. virtual int getstring
(char *&)
This restores strings saved with StateOut::putstring. virtual int
get (std::string &)
This restores a std::string object. virtual int get (char &r, const
char *keyword=0)
These restore data saved with StateOut's put. members. virtual int
get (unsigned int &r, const char *keyword=0)
virtual int get (int &r, const char *keyword=0)
virtual int get (bool &r, const char *keyword=0)
virtual int get (float &r, const char *keyword=0)
virtual int get (double &r, const char *keyword=0)
virtual int get (char *&)
These restore data saved with StateOut's put. virtual int get
(unsigned int *&)
virtual int get (int *&)
virtual int get (float *&)
virtual int get (double *&)
virtual int get_array_char (char *p, int size)
These restore data saved with StateOut's put. virtual int
get_array_uint (unsigned int *p, int size)
virtual int get_array_int (int *p, int size)
virtual int get_array_float (float *p, int size)
virtual int get_array_double (double *p, int size)
template<class T > int get (typename std::vector< T >
&v)
Read an STL vector of data. int node_to_node () const
True if this is a node to node save/restore. virtual int use_directory
()
Returns true of this object uses a directory. virtual int tell ()
Return the current position in the file. virtual void seek (int)
Set the current position in the file. virtual int seekable ()
Return non-zero if seek does anything sensible. int has_directory ()
const
virtual void list_objects (std::ostream &=ExEnv::out0())
List all the objects to the stream. void set_override (const
Ref< KeyVal > &kv)
Give this StateIn a KeyVal object that is used to override
values. const Ref< KeyVal > & override ()
const
Return the KeyVal used to override values.
virtual int get_array_void (void *, int)
int push_key (const char *key)
void pop_key (int n)
const char * key ()
void get_directory ()
int directory_location () const
void find_and_get_directory ()
virtual int getobject (Ref< SavableState > &)
This is used to restore an object. virtual int dir_getobject
(Ref< SavableState > &, const char *name)
This restores objects that are listed in the directory. virtual void
haveobject (int, const Ref< SavableState > &)
When storage has been allocated during object restoration, this routine is
called with the object reference number and the pointer to the new storage
so getpointer can find the data if it is referenced again. virtual void
nextobject (int)
A call to nextobject followed by havepointer(int) is equiv to
havepointer(int,void**);. virtual void haveobject (const
Ref< SavableState > &)
void have_classdesc ()
int need_classdesc ()
virtual int get (const ClassDesc **)
This restores ClassDesc's.

class SavableState
class TranslateDataIn
Restores objects that derive from SavableState.
These restore data saved with StateOut's put. members.
Reimplemented in sc::MsgStateRecv, and sc::StateInText.
These restore data saved with StateOut's put. members. The data is allocated by StateIn.
Reimplemented in sc::MsgStateRecv, and sc::StateInText.
This restores ClassDesc's. It will set the pointer to the address of the static ClassDesc for the class which has the same name as the class that had the ClassDesc that was saved by put(const ClassDesc*).
Reimplemented in sc::MsgStateRecv, and sc::StateInText.
Referenced by get().
These restore data saved with StateOut's put. members. The data must be preallocated by the user.
Reimplemented in sc::StateInText.
Read in the header information. Changes the translation scheme if necessary.
This is used to restore an object. It is called with the reference to the reference being restored. If the data being restored has previously been restored, then the pointer being restored is set to a reference to the previously restored object.
Reimplemented in sc::StateInText.
This restores strings saved with StateOut::putstring.
Reimplemented in sc::StateInText.
List all the objects to the stream. Only StateIn specializations with directories can list objects.
True if this is a node to node save/restore. This is 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.
Set the current position in the file. The default implementation does nothing.
Reimplemented in sc::BcastStateInBin, and sc::StateInBin.
Return non-zero if seek does anything sensible. The default implementation returns 0.
Reimplemented in sc::BcastStateInBin, and sc::StateInBin.
Return the current position in the file.
Reimplemented in sc::BcastStateInBin, and sc::StateInBin.
Returns true of this object uses a directory.
Reimplemented in sc::BcastStateInBin, and sc::StateInBin.
Returns the version of the ClassDesc in the persistent object or -1 if info on the ClassDesc doesn't exist.
Reimplemented in sc::MsgStateRecv.
