# ost\_IPV4Validator(3)

Classes derived from IPV4Address would require an specific validator to pass to the IPV4Address constructor.

## NAME

ost::IPV4Validator - Classes derived from **IPV4Address** would require an specific validator to pass to the **IPV4Address** constructor.

## SYNOPSIS

`#include <address.h>`

Inherited by **ost::IPV4MulticastValidator**.

### Public Member Functions

**IPV4Validator** ()\
 Constructor.  virtual **~IPV4Validator** ()\
 keeps compilers happy.  virtual void **operator()** (const in\_addr address) const =0\
 Pure virtual application operator.

## Detailed Description

Classes derived from **IPV4Address** would require an specific validator to pass to the **IPV4Address** constructor.

This is a base class for classes of function objects used by such derived classes.
