getTypeString

public String getTypeString()

Description copied from interface: BaseReader

Returns String representation of the reader's type. In case if BaseReader.getType() is primitive, the method is equivalent to

invalid @link

{@link #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.

Specified by:

getTypeString in interface BaseReader

Returns:

String representation of reader's type.
