getKeywordlist()

bool ossimNitfInfo::getKeywordlist ( ossimKeywordlist &  kwl, ossim_uint32  entryIndex  ) const

virtual

Method to dump info to a keyword list.

Parameters

kwl	The keyword list to initialize.
entryIndex	Entry to print. Not supported by all info objects yet.

Returns

true on success, false on error.

Reimplemented from ossimInfoBase.

References m_nitfFile, and ossimKeywordlist::parseStream().

{
   // Do a print to a memory stream.
   std::ostringstream out;
   m_nitfFile->print( out, entryIndex );

   std::istringstream in( out.str() );

   // Give the result to the keyword list.
   return kwl.parseStream( in );
}

open() [1/2]

bool ossimNitfInfo::open ( const ossimFilename &  file )

virtual

open method.

Parameters

file	File name to open.

Returns

true on success false on error.

{
   bool result = false;
   
   std::string connectionString = file.c_str();
   std::shared_ptr<ossim::istream> str = ossim::StreamFactoryRegistry::instance()->
      createIstream( file.c_str(), std::ios_base::in|std::ios_base::binary);
   
   if ( str )
   {
      result = open(str, connectionString);
   }
   return result;
}

open() [2/2]

bool ossimNitfInfo::open ( std::shared_ptr< ossim::istream > &  str, const std::string &  connectionString  )

virtual

open method.

Parameters

str	File name to open.

      result = m_nitfFile->parseStream(ossimFilename(connectionString), *str);
   }
   return result;
}

print()

std::ostream & ossimNitfInfo::print ( std::ostream &  out ) const

virtual

Print method.

Parameters

out	Stream to print to.

Returns
