Returns true if column with given name is defined and has an entry in the underlying value array, i.e.
Returns true if column with given name is defined and has an entry in the underlying value array, i.e. was requested in the result set. For columns having null value, returns true.
Displays the content in human readable form, including the names and values of the columns

Generic getter for getting columns of any type.
Generic getter for getting columns of any type. Looks the column up by column name. Column names are case-sensitive.
Generic getter for getting columns of any type.
Generic getter for getting columns of any type. Looks the column up by its index. First column starts at index 0.
Returns a bool column value.
Returns a bool column value. Besides working with bool Cassandra type, it can also read
numbers and strings. Non-zero numbers are converted to true, zero is converted to false.
Strings are converted using String#toBoolean method.
Returns a blob column value as ByteBuffer.
Returns a blob column value as ByteBuffer.
This method is not suitable for reading other types of columns.
Columns of type blob can be also read as Array[Byte] with the generic get method.
Returns a timestamp or timeuuid column value as java.util.Date.
Returns a timestamp or timeuuid column value as java.util.Date.
To convert a timestamp to one of other supported date types, use the generic get method,
for example:
row.get[java.sql.Date](0)
Returns a timestamp or timeuuid column value as org.joda.time.DateTime.
Returns a timestamp or timeuuid column value as org.joda.time.DateTime.
Returns a decimal column value.
Returns a decimal column value.
Can be used with all other floating point types as well as
with strings containing a valid floating point number of arbitrary precision.
Returns a column value as Double.
Returns a column value as Double.
Recommended to use with float and double CQL types.
This method can be also used to read a decimal column, with some loss of precision.
Returns a column value as Float.
Returns a column value as Float.
Recommended to use with float CQL type.
This method can be also used to read a double or decimal column, with some loss of precision.
Returns an inet column value.
Returns an inet column value.
Can be used to read a string containing a valid
Internet address, given either as a host name or IP address.
Returns a column value as a 32-bit integer number.
Returns a column value as a 32-bit integer number.
Besides working with int Cassandra type, it can also read
other integer numbers as bigint or varint and strings.
The string must represent a valid integer number.
The number must be within 32-bit integer range or the TypeConversionException will be thrown.
Reads a list column value and returns it as Scala Vector.
Reads a list column value and returns it as Scala Vector.
A null list is converted to an empty collection.
Items of the list are converted to the given type.
This method can be also used to read set and map column types.
For map, the list items are converted to key-value pairs.
type of the list item, must be given explicitly.
Returns a column value as a 64-bit integer number.
Returns a column value as a 64-bit integer number.
Recommended to use with bigint and counter CQL types
It can also read other column types as int, varint, timestamp and string.
The string must represent a valid integer number.
The number must be within 64-bit integer range or com.datastax.spark.connector.types.TypeConversionException
will be thrown. When used with timestamps, returns a number of milliseconds since epoch.
Reads a map column value.
Reads a map column value.
A null map is converted to an empty collection.
Keys and values of the map are converted to the given types.
type of keys, must be given explicitly.
type of values, must be given explicitly.
Returns a column value by index without applying any conversion.
Returns a column value by index without applying any conversion. The underlying type is the same as the type returned by the low-level Cassandra driver, is implementation defined and may change in the future. Cassandra nulls are returned as Scala nulls.
Reads a set column value.
Reads a set column value.
A null set is converted to an empty collection.
Items of the set are converted to the given type.
This method can be also used to read list and map column types.
For map, the set items are converted to key-value pairs.
type of the set item, must be given explicitly.
Returns the column value converted to a String acceptable by CQL.
Returns the column value converted to a String acceptable by CQL.
All data types that have human readable text representations can be converted.
Note, this is not the same as calling getAny(index).toString which works differently e.g. for dates.
Returns a column value of User Defined Type
Returns a column value of User Defined Type
Returns an uuid column value.
Returns an uuid column value.
Can be used to read a string containing a valid UUID.
Returns a varint column value.
Returns a varint column value.
Can be used with all other integer types as well as
with strings containing a valid integer number of arbitrary size.
Returns index of column with given name or -1 if column not found
Returns index of column with given name or -1 if column not found
Returns true if column value is Cassandra null
Returns true if column value is Cassandra null
Returns true if column value is Cassandra null
Returns true if column value is Cassandra null
