DESCRIPTION

CNPInt manages the persistency of CNInt's. As CNInt is its base class, all methods of CNInt are available.

Constructors:

CNPInt(long val=0);

CNPInt(CNPstream& stream);

CNPInt(CNParam *param);

Initializes the CNPInt. Either the value is given as val ( 0 by default) or it will be read from the persistent stream (reader-constructor).

In addition to the member functions required by CNCL, CNInt provides:

virtual int store_on(CNPstream& s);

int store_on(CNPstream& s, bool no_ptr_check);

Stores the CNPInt on the persistent stream s. The boolean parameter no_ptr_check switches the check for multiple storing off (if set TRUE).

static CNPInt* read_from(CNPstream& s);

Reads the CNPInt from stream s.

static CNObject* object_read_from(CNPstream& s);

Reads from stream s as a CNObject.

CNPID object_id();

Returns the ID of the current Object.

virtual int storer(CNPstream&);

static CNPInt* reader(CNPstream& s);

These two functions are called by the class CNPIO as a connection to the persistent output/reader-construktor.
