15.6 ISInfoAny

ISInfo, ISistream

Synopsis

#include <is/infoany.h>

ISInfoAny isa;

Description

This class is used to read the information whose type is unknown at compilation time. The access to the information attributes is organized in a stream like manner. Single-value attributes can be read using input member operators of this class (>>). Multi-value attributes can be read using one of the get methods. Every call to either one of the the input operators or get methods advances the current stream position to the next attribute. The reset method can be used to reset the current stream position to the beginning.

Example

1: #include "is/infoany.h"

3: IPCPartition partition( "MyPartition" );

4: ISInfoIterator ii( partition, "MyServer" );

5: ISInfoAny isa;

6: while ( ii() ) {

7: ii.value( isa );

8: cout << isa;

9: }

Public Member Functions

ISType::Basic

getAttributeType ( ) const;

Returns type of the attribute at the current stream position. For the definition of the ISType::Basic enumeration see Chapter 15.19.

bool

isAttributeArray ( ) const;

Returns true if the attribute at the current stream position is an array, otherwise returns false.

size_t

countAttributes  ( ) const;

Returns a number of attributes for the information object.

void

reset ( );

Set stream position to the beginning of the stream.

The public >> operators and get member functions are inherited from the ISistream class. For their description see Chapter 15.20.

Related Global Operator

std::ostream  & operator<< ( std::ostream & out, ISInfoAny & isa );

Print out value of the isa to the standard output stream out.
