Public Member Functions inherited from Avro.Generic.DefaultReader
	DefaultReader (Schema writerSchema, Schema readerSchema)
	Constructs the default reader for the given schemas using the DefaultReader. If the reader's and writer's schemas are different this class performs the resolution. This default implementation maps Avro types to .NET types as follows: More...

T	Read< T > (T reuse, Decoder decoder)
	Reads an object off the stream. More...

object	Read (object reuse, Schema writerSchema, Schema readerSchema, Decoder d)
	Reads an object off the stream. More...

Protected Member Functions
override object	ReadRecord (object reuse, RecordSchema writerSchema, Schema readerSchema, Decoder dec)
	Deserializes a record from the stream. More...

override object	ReadFixed (object reuse, FixedSchema writerSchema, Schema readerSchema, Decoder d)
	Deserializes a fixed object and returns the object. The default implementation uses CreateFixed() and GetFixedBuffer() and returns what CreateFixed() returned. More...

override object	ReadEnum (object reuse, EnumSchema writerSchema, Schema readerSchema, Decoder dec)
	Reads an enum from the given decoder More...

override object	ReadArray (object reuse, ArraySchema writerSchema, Schema readerSchema, Decoder dec)
	Reads an array from the given decoder More...

override object	ReadMap (object reuse, MapSchema writerSchema, Schema readerSchema, Decoder d)
	Deserialized an avro map. The default implementation creates a new map using CreateMap() and then adds elements to the map using AddMapEntry(). More...

virtual string	getTargetType (Schema schema)
	Gets the target type name in the given schema More...

Protected Member Functions inherited from Avro.Generic.DefaultReader
virtual object	ReadNull (Schema readerSchema, Decoder d)
	Deserializes a null from the stream. More...

T	Read< T > (Schema.Type tag, Schema readerSchema, Reader< T > reader)
	A generic function to read primitive types More...

virtual object	CreateRecord (object reuse, RecordSchema readerSchema)
	Creates a new record object. Derived classes can override this to return an object of their choice. More...

virtual bool	TryGetField (object record, string fieldName, int fieldPos, out object value)
	Used by the default implementation of ReadRecord() to get the existing field of a record object. The derived classes can override this to make their own interpretation of the record object. More...

virtual void	AddField (object record, string fieldName, int fieldPos, object fieldValue)
	Used by the default implementation of ReadRecord() to add a field to a record object. The derived classes can override this to suit their own implementation of the record object. More...

virtual object	CreateEnum (object reuse, EnumSchema es, string symbol)
	Used by the default implementation of ReadEnum to construct a new enum object. More...

virtual object	CreateArray (object reuse, ArraySchema rs)
	Creates a new array object. The initial size of the object could be anything. The users should use GetArraySize() to determine the size. The default implementation creates an `object[]`. More...

virtual int	GetArraySize (object array)
	Returns the size of the given array object. More...

virtual void	ResizeArray (ref object array, int n)
	Resizes the array to the new value. More...

virtual void	SetArrayElement (object array, int index, object value)
	Assigns a new value to the object at the given index More...

virtual object	GetArrayElement (object array, int index)
	Returns the element at the given index. More...

virtual object	CreateMap (object reuse, MapSchema ms)
	Used by the default implementation of ReadMap() to create a fresh map object. The default implementation of this method returns a IDictionary<string, map>. More...

virtual void	AddMapEntry (object map, string key, object value)
	Adds an entry to the map. More...

virtual object	ReadUnion (object reuse, UnionSchema writerSchema, Schema readerSchema, Decoder d)
	Deserialized an object based on the writer's union schema. More...

virtual object	ReadLogical (object reuse, LogicalSchema writerSchema, Schema readerSchema, Decoder d)
	Deserializes an object based on the writer's logical schema. Uses the underlying logical type to convert the value to the logical type. More...

virtual object	CreateFixed (object reuse, FixedSchema rs)
	Returns a fixed object. More...

virtual byte[]	GetFixedBuffer (object f)
	Returns a buffer of appropriate size to read data into. More...

virtual void	Skip (Schema writerSchema, Decoder d)
	Skip an instance of a schema. More...

Detailed Description

Reader class for reading data and storing into specific classes

Constructor & Destructor Documentation

◆ SpecificDefaultReader()

Avro.Specific.SpecificDefaultReader.SpecificDefaultReader	(	Schema	writerSchema,
		Schema	readerSchema
	)

inline

Constructor

Parameters

writerSchema	schema of the object that wrote the data
readerSchema	schema of the object that will store the data

Member Function Documentation

◆ getTargetType()

virtual string Avro.Specific.SpecificDefaultReader.getTargetType ( Schema schema )

inlineprotectedvirtual

Gets the target type name in the given schema

Parameters

schema schema containing the type to be determined

Returns: Name of the type

◆ ReadArray()

override object Avro.Specific.SpecificDefaultReader.ReadArray	(	object	reuse,
		ArraySchema	writerSchema,
		Schema	readerSchema,
		Decoder	dec
	)

inlineprotectedvirtual

Reads an array from the given decoder

Parameters

reuse	object to store data read
writerSchema	schema of the object that wrote the data
readerSchema	schema of the object that will store the data
dec	decoder object that contains the data to be read

Returns: array

Reimplemented from Avro.Generic.DefaultReader.

◆ ReadEnum()

override object Avro.Specific.SpecificDefaultReader.ReadEnum	(	object	reuse,
		EnumSchema	writerSchema,
		Schema	readerSchema,
		Decoder	dec
	)

inlineprotectedvirtual

Reads an enum from the given decoder

Parameters

reuse	object to store data read
writerSchema	schema of the object that wrote the data
readerSchema	schema of the object that will store the data
dec	decoder object that contains the data to be read

Returns: enum value

Reimplemented from Avro.Generic.DefaultReader.

◆ ReadFixed()

override object Avro.Specific.SpecificDefaultReader.ReadFixed	(	object	reuse,
		FixedSchema	writerSchema,
		Schema	readerSchema,
		Decoder	d
	)

inlineprotectedvirtual

Deserializes a fixed object and returns the object. The default implementation uses CreateFixed() and GetFixedBuffer() and returns what CreateFixed() returned.

Parameters

reuse	If appropriate, uses this object instead of creating a new one.
writerSchema	The FixedSchema the writer used during serialization.
readerSchema	The schema that the reader uses. Must be a FixedSchema with the same size as the writerSchema.
d	The decoder for deserialization.

Returns: The deserialized object.

Reimplemented from Avro.Generic.DefaultReader.

◆ ReadMap()

override object Avro.Specific.SpecificDefaultReader.ReadMap	(	object	reuse,
		MapSchema	writerSchema,
		Schema	readerSchema,
		Decoder	d
	)

inlineprotectedvirtual

Deserialized an avro map. The default implementation creates a new map using CreateMap() and then adds elements to the map using AddMapEntry().

Parameters

reuse	If appropriate, use this instead of creating a new map object.
writerSchema	The schema the writer used to write the map.
readerSchema	The schema the reader is using.
d	The decoder for serialization.

Returns: The deserialized map object.

Reimplemented from Avro.Generic.DefaultReader.

◆ ReadRecord()

override object Avro.Specific.SpecificDefaultReader.ReadRecord	(	object	reuse,
		RecordSchema	writerSchema,
		Schema	readerSchema,
		Decoder	dec
	)

inlineprotectedvirtual

Deserializes a record from the stream.

Parameters

reuse	If not null, a record object that could be reused for returning the result
writerSchema	The writer's RecordSchema
readerSchema	The reader's schema, must be RecordSchema too.
dec	The decoder for deserialization

Returns: The record object just read

Reimplemented from Avro.Generic.DefaultReader.
