SparkList

public SparkList(SparkSqlTypeConverter converter,
                 org.apache.cassandra.spark.data.CqlField.CqlCollection list)

Method Detail

dataType

public org.apache.spark.sql.types.DataType dataType(org.apache.cassandra.bridge.BigNumberConfig bigNumberConfig)

Specified by:

dataType in interface SparkType

Parameters:

bigNumberConfig - specifies the scale and precision to be used for VarInt and Decimal types.

Returns:

the SparkSQL `org.apache.spark.sql.types.DataType` for this SparkType.

toSparkSqlType

public java.lang.Object toSparkSqlType(@NotNull
                                       java.lang.Object value,
                                       boolean isFrozen)

Specified by:

toSparkSqlType in interface SparkType

Parameters:

value - the Cassandra value.

isFrozen - true if the type is frozen.

Returns:

the value mapped to the Spark equivalent data type.

sparkSqlRowValue

public java.lang.Object sparkSqlRowValue(org.apache.spark.sql.catalyst.expressions.GenericInternalRow row,
                                         int position)

Specified by:

sparkSqlRowValue in interface SparkType

Parameters:

row - a SparkSQL `org.apache.spark.sql.catalyst.expressions.GenericInternalRow`

position - position in row

Returns:

the SparkSQL value at `position` in the `row` converted back into test type - used only in the test system.

                                         int position)

Specified by:

sparkSqlRowValue in interface SparkType

Parameters:

row - a SparkSQL `org.apache.spark.sql.Row`

position - position in row

Returns:
