CompositeJsonToAvroReader

public CompositeJsonToAvroReader()

CompositeJsonToAvroReader

public CompositeJsonToAvroReader(java.util.List<AvroTypeConverter> additionalConverters)

this constructor allows you to specify custom converters. It can be used to convert custom java types, or avro schema with logical type.

Parameters:

additionalConverters - additional converters that implement AvroTypeConverter. These converters will override default converters.

Description copied from interface: JsonToAvroReader

allow to convert a json field to type corresponding avro type

Specified by:

read in interface JsonToAvroReader

Parameters:

field - the avro field to create

schema - the schema associated to the field

jsonValue - the json jsonValue of the field

path - the path of the field on the json

silently - should be false to throw an error in case of incompatible java type for the avro type

Returns:

the converted jsonValue
