void	Write< T > (T value, Encoder encoder)

virtual void	Write (Schema schema, object value, Encoder encoder)
	Examines the schema and dispatches the actual work to one of the other methods of this class. This allows the derived classes to override specific methods and get custom results. More...

Protected Member Functions
override void	WriteRecord (RecordSchema schema, object value, Encoder encoder)
	Serialized a record using the given RecordSchema. It uses GetField method to extract the field value from the given object. More...

override void	WriteFixed (FixedSchema schema, object value, Encoder encoder)
	Validates that the record is a fixed record object and that the schema in the object is the same as the given writer schema. Writes the given fixed record into the given encoder More...

override void	WriteEnum (EnumSchema schema, object value, Encoder encoder)
	Writes the given enum value into the given encoder. More...

override void	WriteArray (ArraySchema schema, object value, Encoder encoder)
	Serialized an array. The default implementation calls EnsureArrayObject() to ascertain that the given value is an array. It then calls GetArrayLength() and GetArrayElement() to access the members of the array and then serialize them. More...

	Writes the given map into the given encoder. More...

override void	WriteUnion (UnionSchema us, object value, Encoder encoder)
	Resolves the given value against the given UnionSchema and serializes the object against the resolved schema member. The default implementation of this method uses ResolveUnion to find the member schema within the UnionSchema. More...

	A generic method to serialize primitive Avro types. More...

virtual void	EnsureRecordObject (RecordSchema s, object value)

virtual object	GetField (object value, string fieldName, int fieldPos)
	Extracts the field value from the given object. In this default implementation, value should be of type GenericRecord. More...

virtual void	EnsureArrayObject (object value)
	Checks if the given object is an array. If it is a valid array, this function returns normally. Otherwise, it throws an exception. The default implementation checks if the value is an array. More...

virtual long	GetArrayLength (object value)
	Returns the length of an array. The default implementation requires the object to be an array of objects and returns its length. The defaul implementation gurantees that EnsureArrayObject() has been called on the value before this function is called. More...

virtual object	GetArrayElement (object value, long index)
	Returns the element at the given index from the given array object. The default implementation requires that the value is an object array and returns the element in that array. The defaul implementation gurantees that EnsureArrayObject() has been called on the value before this function is called. More...

virtual void	EnsureMapObject (object value)
	Checks if the given object is a map. If it is a valid map, this function returns normally. Otherwise, it throws an exception. The default implementation checks if the value is an IDictionary<string, object>. More...

virtual long	GetMapSize (object value)
	Returns the size of the map object. The default implementation gurantees that EnsureMapObject has been successfully called with the given value. The default implementation requires the value to be an IDictionary<string, object> and returns the number of elements in it. More...

virtual IEnumerable < KeyValuePair< string, object > >	GetMapValues (object value)
	Returns the contents of the given map object. The default implementation guarantees that EnsureMapObject has been called with the given value. The defualt implementation of this method requires that the value is an IDictionary<string, object> and returns its contents. More...

virtual int	ResolveUnion (UnionSchema us, object obj)
	Finds the branch within the given UnionSchema that matches the given object. The default implementation calls Matches() method in the order of branches within the UnionSchema. If nothing matches, throws an exception. More...

Class for writing data from any specific objects

Constructor & Destructor Documentation

Avro.Specific.SpecificDefaultWriter.SpecificDefaultWriter ( Schema schema )

inline

Constructor

Parameters

schema schema of the object to be written

Member Function Documentation

override void Avro.Specific.SpecificDefaultWriter.WriteArray	(	ArraySchema	schema,
		object	value,
		Encoder	encoder
	)

inlineprotectedvirtual

Serialized an array. The default implementation calls EnsureArrayObject() to ascertain that the given value is an array. It then calls GetArrayLength() and GetArrayElement() to access the members of the array and then serialize them.

Parameters

schema	The ArraySchema for serialization
value	The value being serialized
encoder	The encoder for serialization

Reimplemented from Avro.Generic.DefaultWriter.

override void Avro.Specific.SpecificDefaultWriter.WriteEnum	(	EnumSchema	schema,
		object	value,
		Encoder	encoder
	)

inlineprotectedvirtual

Writes the given enum value into the given encoder.

Parameters

schema	writer schema
value	enum value
encoder	encoder to write to

Reimplemented from Avro.Generic.DefaultWriter.

override void Avro.Specific.SpecificDefaultWriter.WriteFixed	(	FixedSchema	schema,
		object	value,
		Encoder	encoder
	)

inlineprotectedvirtual

Validates that the record is a fixed record object and that the schema in the object is the same as the given writer schema. Writes the given fixed record into the given encoder

Parameters

schema	writer schema
value	fixed object to write
encoder	encoder to write to

Reimplemented from Avro.Generic.DefaultWriter.

override void Avro.Specific.SpecificDefaultWriter.WriteMap	(	MapSchema	schema,
		object	value,
		Encoder	encoder
	)

inlineprotectedvirtual

Writes the given map into the given encoder.

Parameters

schema	writer schema
value	map to write
encoder	encoder to write to

Reimplemented from Avro.Generic.DefaultWriter.

override void Avro.Specific.SpecificDefaultWriter.WriteRecord	(	RecordSchema	schema,
		object	value,
		Encoder	encoder
	)

inlineprotectedvirtual

Serialized a record using the given RecordSchema. It uses GetField method to extract the field value from the given object.

Parameters

schema	The RecordSchema to use for serialization
value	The value to be serialized
encoder	The Encoder for serialization

Reimplemented from Avro.Generic.DefaultWriter.

override void Avro.Specific.SpecificDefaultWriter.WriteUnion	(	UnionSchema	us,
		object	value,
		Encoder	encoder
	)

inlineprotectedvirtual

Resolves the given value against the given UnionSchema and serializes the object against the resolved schema member. The default implementation of this method uses ResolveUnion to find the member schema within the UnionSchema.

Parameters

us	The UnionSchema to resolve against
value	The value to be serialized
encoder	The encoder for serialization

Reimplemented from Avro.Generic.DefaultWriter.
