Member Function Documentation

create_cleared_copy()

virtual std::shared_ptr<column_statistics> turi::v2::ml_data_internal::column_statistics::create_cleared_copy ( ) const

pure virtual

Create a copy with the index cleared.

factory_create()

static std::shared_ptr<column_statistics> turi::v2::ml_data_internal::column_statistics::factory_create ( const std::map< std::string, variant_type > &  creation_options )

static

The factory method for loading and instantiating the proper class

finalize()

virtual void turi::v2::ml_data_internal::column_statistics::finalize ( )

pure virtual

Perform final computations on the different statistics. Called after all the data is filled.

Implemented in turi::v2::ml_data_internal::basic_column_statistics.

get_version()

virtual size_t turi::v2::ml_data_internal::column_statistics::get_version ( ) const

pure virtual

Returns the current version used for the serialization.

is_equal()

virtual bool turi::v2::ml_data_internal::column_statistics::is_equal ( const column_statistics *  other ) const

pure virtual

Equality testing in subclass – slow! Use for debugging/testing. Upcast this to superclass to do full testing.

load_version()

virtual void turi::v2::ml_data_internal::column_statistics::load_version ( turi::iarchive &  iarc, size_t  version  )

pure virtual

Load the object.

num_observations()

virtual size_t turi::v2::ml_data_internal::column_statistics::num_observations ( ) const

inlinevirtual

Returns the number of seen by the methods collecting the statistics.

Reimplemented in turi::v2::ml_data_internal::basic_column_statistics.

Definition at line 49 of file column_statistics.hpp.

operator!=()

bool turi::v2::ml_data_internal::column_statistics::operator!=

(

const column_statistics &

other

)

const

Inequality testing – slow! Use for debugging/testing

operator==()

bool turi::v2::ml_data_internal::column_statistics::operator==

(

const column_statistics &

other

)

const

Equality testing – slow! Use for debugging/testing

save_impl()

virtual void turi::v2::ml_data_internal::column_statistics::save_impl ( turi::oarchive &  oarc ) const

pure virtual

Serialize the object (save).

set_data()

virtual void turi::v2::ml_data_internal::column_statistics::set_data ( const std::map< std::string, variant_type > &  params )

inlinevirtual

One way to set the statistics. Used by the serialization converters.
