BaseReaderString representation of the reader's type. In case if
BaseReader.getType() is primitive, the method is equivalent to
#getType().getMinorType().name(). If the reader has minor type
equal to TypeProtos.MinorType.DICT,
DICT<keyMinorType,valueMinorType>, with keyMinorType
and valueMinorType being key's and value's minor types
respectively, will be returned. Used in typeOf UDF.getTypeString in interface BaseReaderString representation of reader's type.Copyright © 1970 The Apache Software Foundation. All rights reserved.
