sc::StateInFile(3) MPQC sc::StateInFile(3) NAME sc::StateInFile - Reads state information from a file. SYNOPSIS #include <state_file.h> Inherits sc::StateIn. Inherited by sc::StateInBin, and sc::StateInText. Public Member Functions StateInFile () State information will be obtained from cin. StateInFile (std::istream &s) State information will be obtained from fp. StateInFile (const char *name) State information will be obtained from name. virtual int open (const char *name) State information will be obtained from name. virtual void close () Close the output file. Public Member Functions inherited from sc::StateIn 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. Public Member Functions inherited from sc::DescribedClass DescribedClass (const DescribedClass &) DescribedClass & operator= (const DescribedClass &) ClassDesc * class_desc () const throw () This returns the unique pointer to the ClassDesc corresponding to the given type_info object. const char * class_name () const Return the name of the object's exact type. int class_version () const Return the version of the class. virtual void print (std::ostream &=ExEnv::out0()) const Print the object. Public Member Functions inherited from sc::RefCount int lock_ptr () const Lock this object. int unlock_ptr () const Unlock this object. void use_locks (bool inVal) start and stop using locks on this object refcount_t nreference () const Return the reference count. refcount_t reference () Increment the reference count and return the new count. refcount_t dereference () Decrement the reference count and return the new count. int managed () const void unmanage () Turn off the reference counting mechanism for this object. int managed () const Return 1 if the object is managed. Otherwise return 0. Public Member Functions inherited from sc::Identity Identifier identifier () Return the Identifier for this argument.
