方法的具体详情如下:
包路径:org.apache.gobblin.util.AvroUtils
类名称:AvroUtils
方法名:getFieldSchema
[英]Given a GenericRecord, this method will return the schema of the field specified by the path parameter. The fieldLocation parameter is an ordered string specifying the location of the nested field to retrieve. For example, field1.nestedField1 takes the the schema of the field "field1", and retrieves the schema "nestedField1" from it.
[中]给定GenericRecord,此方法将返回path参数指定的字段的架构。fieldLocation参数是一个有序字符串,指定要检索的嵌套字段的位置。例如,field1。nestedField1获取字段“field1”的架构,并从中检索架构“nestedField1”。
