Method Detail

command

public static FlightDescriptor command(byte[] cmd)

path

public static FlightDescriptor path(Iterable<String> path)

path

public static FlightDescriptor path(String... path)

isCommand

public boolean isCommand()

getPath

public List<String> getPath()

getCommand

public byte[] getCommand()

serialize

public ByteBuffer serialize()

Get the serialized form of this protocol message.

Intended to help interoperability by allowing non-Flight services to still return Flight types.

deserialize

public static FlightDescriptor deserialize(ByteBuffer serialized)
                                    throws IOException

Parse the serialized form of this protocol message.

Intended to help interoperability by allowing Flight clients to obtain stream info from non-Flight services.

Parameters:

serialized - The serialized form of the FlightDescriptor, as returned by serialize().

Returns:

The deserialized FlightDescriptor.

Throws:

IOException - if the serialized form is invalid.
