Method Detail

orderAscending

public SchemaBuilder.FieldBuilder<R> orderAscending()

orderDescending

public SchemaBuilder.FieldBuilder<R> orderDescending()

Set this field to have descending order. Descending is the default

orderIgnore

public SchemaBuilder.FieldBuilder<R> orderIgnore()

Set this field to ignore order.

type

public SchemaBuilder.FieldTypeBuilder<R> type()

Final step in configuring this field, finalizing name, namespace, alias, and order.

Returns:

A builder for the field's type and default value.

type

public SchemaBuilder.GenericDefault<R> type(Schema type)

Final step in configuring this field, finalizing name, namespace, alias, and order. Sets the field's type to the provided schema, returns a SchemaBuilder.GenericDefault.

type

public SchemaBuilder.GenericDefault<R> type(String name)

Final step in configuring this field, finalizing name, namespace, alias, and order. Sets the field's type to the schema by name reference.

The name must correspond with a named schema that has already been created in the context of this builder. The name may be a fully qualified name, or a short name. If it is a short name, the namespace context of this builder will be used.

The name and namespace context rules are the same as the Avro schema JSON specification.

type

public SchemaBuilder.GenericDefault<R> type(String name,
                                            String namespace)

Final step in configuring this field, finalizing name, namespace, alias, and order. Sets the field's type to the schema by name reference.

The name must correspond with a named schema that has already been created in the context of this builder. The name may be a fully qualified name, or a short name. If it is a full name, the namespace is ignored. If it is a short name, the namespace provided is used. If the namespace provided is null, the namespace context of this builder will be used.

The name and namespace context rules are the same as the Avro schema JSON specification.

self

protected SchemaBuilder.FieldBuilder<R> self()

Description copied from class: SchemaBuilder.PropBuilder

a self-type for chaining builder subclasses. Concrete subclasses must return 'this'
