Method Detail

isValid

public boolean isValid(long value)

Specified by:

isValid in interface ParquetDataColumnReader

Overrides:

isValid in class ParquetDataColumnReaderFactory.DefaultParquetDataColumnReader

Parameters:

value - data to be checked for validity

Returns:

is data valid for the type The type of the data in Parquet files need not match the type in HMS. In that case the value returned to the user will depend on the data. If the data value is within the valid range accommodated by the HMS type, the data will be returned as is. When data is not within the valid range, a NULL will be returned. These functions will do the appropriate check.
