	A convenience method for ReadFixed(buffer, 0, buffer.Length);

override int	ReadEnum ()
	Reads an enum AvroType
override 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. }
override long	ReadArrayNext ()
	See ReadArrayStart().
override void	SkipArray ()
	Skips an array on the stream.
override 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. }

Member Function Documentation

Configure() [1/2]

void Avro.IO.JsonDecoder.Configure ( Stream  stream )

inline

Reconfigures this JsonDecoder to use the InputStream provided. Otherwise, this JsonDecoder will reset its state and then reconfigure its input.

Parameters

stream

The InputStream to read from. Cannot be null.

Configure() [2/2]

void Avro.IO.JsonDecoder.Configure ( string  str )

inline

Reconfigures this JsonDecoder to use the String provided for input. Otherwise, this JsonDecoder will reset its state and then reconfigure its input.

Parameters

str	The String to read from. Cannot be null.
