	null is written as zero bytes
bool	ReadBoolean ()
	a boolean is written as a single byte whose value is either 0 (false) or 1 (true).

	See ReadArrayStart().
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 entriess 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

long Avro::IO::BinaryDecoder::ReadArrayNext ( ) [inline]

See ReadArrayStart().

Returns:: The number of array entries in the next chunk, 0 if there are no more entries.

Implements Avro::IO::Decoder.

long Avro::IO::BinaryDecoder::ReadArrayStart ( ) [inline]

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. }

Returns:: The number of entries in the initial chunk, 0 if the array is empty.

Implements Avro::IO::Decoder.

bool Avro::IO::BinaryDecoder::ReadBoolean ( ) [inline]

a boolean is written as a single byte whose value is either 0 (false) or 1 (true).

Returns:

Implements Avro::IO::Decoder.

byte [] Avro::IO::BinaryDecoder::ReadBytes ( ) [inline]

Bytes are encoded as a long followed by that many bytes of data.

Returns:

Implements Avro::IO::Decoder.

double Avro::IO::BinaryDecoder::ReadDouble ( ) [inline]

A double is written as 8 bytes. The double is converted into a 64-bit integer using a method equivalent to Java's doubleToLongBits and then encoded in little-endian format.
