Public Member Functions
abstract void	ReadNull ()
	Reads a null Avro type.
abstract bool	ReadBoolean ()
	Read a boolean Avro type
abstract int	ReadInt ()
	Reads an int Avro type.
abstract long	ReadLong ()
	Reads a long Avro type.
abstract float	ReadFloat ()
	Reads a float Avro type
abstract double	ReadDouble ()
	Reads a double Avro type
abstract byte[]	ReadBytes ()
	Reads the bytes Avro type
abstract string	ReadString ()
	Reads a string Avro type
abstract int	ReadEnum ()
	Reads an enum AvroType
abstract long	ReadArrayStart ()
	Starts reading the array Avro type. This, together with ReadArrayNext() is used to read the items from Avro array. This returns the number of entries in the initial chunk. After consuming the chunk, the client should call ReadArrayNext() to get the number of entries in the next chunk. The client should repeat the procedure until there are no more entries in the array.for (int n = decoder.ReadArrayStart(); n > 0; n = decoder.ReadArrayNext()) { // Read one array entry. }
abstract long	ReadArrayNext ()
	See ReadArrayStart().
abstract long	ReadMapStart ()
	Starts reading the map Avro type. This, together with ReadMapNext() is used to read the entries from Avro map. This returns the number of entries in the initial chunk. After consuming the chunk, the client should call ReadMapNext() to get the number of entries in the next chunk. The client should repeat the procedure until there are no more entries in the array. for (int n = decoder.ReadMapStart(); n > 0; n = decoder.ReadMapNext()) { // Read one map entry. }
abstract long	ReadMapNext ()
	See ReadMapStart().
abstract int	ReadUnionIndex ()
	Reads the index, which determines the type in an union Avro type.
abstract void	ReadFixed (byte[] buffer)
	A convenience method for ReadFixed(buffer, 0, buffer.Length);
abstract void	ReadFixed (byte[] buffer, int start, int length)
	Read a Fixed Avro type of length.
abstract void	SkipNull ()
	Skips a null Avro type on the stream.
abstract void	SkipBoolean ()
	Skips a boolean Avro type on the stream.
abstract void	SkipInt ()
	Skips a int Avro type on the stream.
