Fields¶

gnss_message_type_t message_type

Type of GNSS message.

Methods¶

void writeToStream(mrpt::serialization::CArchive& out) const

Save to binary stream.

Launches an exception upon error

void readFromStream(mrpt::serialization::CArchive& in)

Load from binary stream into this existing object.

Launches an exception upon error.

virtual void dumpToStream(std::ostream& out) const = 0

Dumps the contents of the observation in a human-readable form to a given output stream.

See also:

dumpToConsole()

virtual void fixEndianness()

If we are in a big endian system, reverse all fields >1 byte to fix its representation.

Only in binary frames, text-based derived classes obviously do not need to reimplement this one.

virtual void dumpToConsole(std::ostream& o) const

Dumps the contents of the observation in a human-readable form to an std::ostream (set to std::cout to print to console)

virtual bool getAllFieldDescriptions(] std::ostream& o) const

Dumps a header for getAllFieldValues()

Returns:

false if not implemented for this message type

virtual bool getAllFieldValues(] std::ostream& o) const

Dumps a line with the sequence of all field values (without a line feed at the end).

Returns:

false if not implemented for this message type
