Bytes	A sequence of 8-bit unsigned bytes.
String	An unicode character sequence.
Record	A logical collection of fields.
Enumeration	An enumeration.
Array	An array of values.
Map	A map of values with string keys.
Union	A union.
Fixed	A fixed-length byte string.

Constructor & Destructor Documentation

Schema()

Avro.Schema.Schema ( Type  type, PropertyMap  props  )

inlineprotected

Constructor for schema class

Parameters

type
props	dictionary that provides access to custom properties

Member Function Documentation

areEqual()

static bool Avro.Schema.areEqual ( object  o1, object  o2  )

inlinestaticprotected

Compares two objects, null is equal to null

Parameters

o1	first object
o2	second object

Returns

true if two objects are equal, false otherwise

CanRead()

virtual bool Avro.Schema.CanRead ( Schema  writerSchema )

inlinevirtual

Returns true if and only if data written using writerSchema can be read using the current schema according to the Avro resolution rules.

Parameters

writerSchema

The writer's schema to match against.

Returns

True if and only if the current schema matches the writer's.

Reimplemented in Avro.RecordSchema, Avro.EnumSchema, Avro.UnionSchema, Avro.FixedSchema, Avro.MapSchema, Avro.PrimitiveSchema, Avro.LogicalSchema, and Avro.ArraySchema.

GetHashCode()

override int Avro.Schema.GetHashCode ( )

inline

Hash code function

Returns

getHashCode()

static int Avro.Schema.getHashCode ( object  obj )

inlinestaticprotected

Hash code helper function

Parameters

obj

Returns

GetProperty()

string Avro.Schema.GetProperty ( string  key )

inline

Returns the schema's custom property value given the property name

Parameters

key	custom property name

Returns

custom property value

GetTypeString()

static string Avro.Schema.GetTypeString ( Type  type )

inlinestatic

Returns symbol name for the given schema type

Parameters

type	schema type

Returns

symbol name

Parse()

static Schema Avro.Schema.Parse ( string  json )

inlinestatic

Parses a given JSON string to create a new schema object

Parameters

json	JSON string

Returns

new Schema object

ToString()

override string Avro.Schema.ToString ( )

inline

Returns the canonical JSON representation of this schema.

Returns

The canonical JSON representation of this schema.

Property Documentation

Fullname

virtual string Avro.Schema.Fullname

get

The name of this schema. If this is a named schema such as an enum, it returns the fully qualified name for the schema. For other schemas, it returns the type of the schema.

Name

abstract string Avro.Schema.Name

get

If this is a record, enum or fixed, returns its name, otherwise the name the primitive type.

Tag

Type Avro.Schema.Tag

get

Schema type property
