Public Member Functions
	SpecificDatumWriter (Schema schema)
	Initializes a new instance of the SpecificDatumWriter<T> class. More...
Public Member Functions inherited from Avro.Generic.PreresolvingDatumWriter< T >
void	Write (T datum, Encoder encoder)
	Write a datum. Traverse the schema, depth first, writing each leaf value in the schema from the datum to the output.

Protected Member Functions
override void	WriteRecordFields (object recordObj, RecordFieldWriter[] writers, Encoder encoder)
	Writes each field of a record to the encoder.
override void	EnsureRecordObject (RecordSchema recordSchema, object value)
	Ensures that the given value is a record and that it corresponds to the given schema. Throws an exception if either of those assertions are false.
override void	WriteField (object record, string fieldName, int fieldPos, WriteItem writer, Encoder encoder)
	Writes a field from the record to the encoder using the writer .
override WriteItem	ResolveEnum (EnumSchema es)
	Serializes an enumeration.
override void	WriteFixed (FixedSchema schema, object value, Encoder encoder)
	Serialized a fixed object. The default implementation requires that the value is a GenericFixed object with an identical schema as es.
override bool	UnionBranchMatches (Schema sc, object obj)
	Tests whether the given schema an object are compatible.
Protected Member Functions inherited from Avro.Generic.PreresolvingDatumWriter< T >
delegate void	WriteItem (object value, Encoder encoder)
	Defines the signature for a method that writes a value to an encoder. More...
	PreresolvingDatumWriter (Schema schema, ArrayAccess arrayAccess, MapAccess mapAccess)
	Initializes a new instance of the PreresolvingDatumWriter<T> class. More...
void	WriteNull (object value, Encoder encoder)
	Serializes a "null" More...
void	Write< TValue > (object value, Schema.Type tag, Writer< TValue > writer)
	A generic method to serialize primitive Avro types. More...
WriteItem	ResolveArray (ArraySchema schema)
	Creates a WriteItem delegate that serializes 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...
WriteItem	ResolveLogical (LogicalSchema schema)
	Serializes a logical value object by using the underlying logical type to convert the value to its base value. More...
void	WriteMap (WriteItem itemWriter, object value, Encoder encoder)
	Serializes a map. The default implementation first ensure that the value is indeed a map and then uses GetMapSize() and GetMapElements() to access the contents of the map. More...
int	ResolveUnion (UnionSchema us, Schema[] branchSchemas, 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...
