Member Function Documentation

bool dballe::AofFile::read ( Rawmsg &  msg )

virtual

Read a message from the file.

Parameters

msg	The Rawmsg that will hold the data.

Returns

true if a message has been found in the file, else false.

Implements dballe::File.

bool dballe::AofFile::read_record ( std::string &  res )

protected

Read a Fortran Unformatted Sequential Binary record from a file.

Parameters

res	The data read. The resulting data is an array of 32bit words that will be byteswapped to native endianness if needed.

Returns

true if a record was found, false on EOF

virtual Encoding dballe::AofFile::type ( ) const throw ( )

inlinevirtual

Get the name of the dba_file.

Returns

The file name.

Implements dballe::File.

void dballe::AofFile::write ( const Rawmsg &  msg )

virtual

Write the encoded message data to the file.

Parameters

msg	The ::dba_rawmsg with the encoded data to write

Reimplemented from dballe::File.

void dballe::AofFile::write_record ( const std::string &  res )

protected

Write a Fortran Unformatted Sequential Binary record to a file.

Parameters

res	The data to be written, considered an array of 32bit words that will be byteswapped for endianness if needed

void dballe::AofFile::write_record ( const uint32_t *  words, size_t  wordcount  )

protected

Write a Fortran Unformatted Sequential Binary record to a file.

Parameters

words

The data to be written, as an array of 32bit words that will be byteswapped for endianness if needed
