Detailed Description

Class for union schemas.

Member Function Documentation

CanRead()

override bool Avro.UnionSchema.CanRead ( Schema  writerSchema )

inlinevirtual

Checks if this schema can read data written by the given schema. Used for decoding data.

Parameters

writerSchema

writer schema

Returns

true if this and writer schema are compatible based on the AVRO specification, false otherwise

Reimplemented from Avro.Schema.

Create()

static UnionSchema Avro.UnionSchema.Create ( List< Schema >  schemas, PropertyMap  customProperties = null  )

inlinestatic

Creates a new UnionSchema

Parameters

schemas	The union schemas
customProperties	Dictionary that provides access to custom properties

Returns

New UnionSchema

Equals()

override bool Avro.UnionSchema.Equals ( object  obj )

inline

Compares two union schema objects.

Parameters

obj	union schema object to compare against this schema

Returns

true if objects are equal, false otherwise

GetHashCode()

override int Avro.UnionSchema.GetHashCode ( )

inline

Hash code function.

Returns

MatchingBranch()

int Avro.UnionSchema.MatchingBranch ( Schema  s )

inline

Returns the index of a branch that can read the data written by the given schema s.

Parameters

s	The schema to match the branches against.

Returns

The index of the matching branch. If non matches a -1 is returned.

Property Documentation

this[int index]

Schema Avro.UnionSchema.this[int index]

get

Returns the schema at the given branch.

Parameters

index

Index to the branch, starting with 0.

Returns

The branch corresponding to the given index.
