Detailed Description

Builder to build options for writer_json()

Definition at line 1096 of file io/json.hpp.

Constructor & Destructor Documentation

json_writer_options_builder() [1/2]

cudf::io::json_writer_options_builder::json_writer_options_builder ( )

explicitdefault

Default constructor.

This has been added since Cython requires a default constructor to create objects on stack.

json_writer_options_builder() [2/2]

cudf::io::json_writer_options_builder::json_writer_options_builder ( sink_info const &  sink, table_view const &  table  )

inlineexplicit

Constructor from sink and table.

Parameters

sink	The sink used for writer output
table	Table to be written to output

Definition at line 1113 of file io/json.hpp.

Member Function Documentation

build()

json_writer_options&& cudf::io::json_writer_options_builder::build ( )

inline

This has been added since Cython does not support overloading of conversion operators.

Returns

Built json_writer_options object's r-value reference

Definition at line 1226 of file io/json.hpp.

false_value()

json_writer_options_builder& cudf::io::json_writer_options_builder::false_value ( std::string  val )

inline

Sets string used for values == 0 in INT8 types.

Parameters

val	String to represent values == 0 in INT8 types

Returns

this for chaining

Definition at line 1208 of file io/json.hpp.

include_nulls()

json_writer_options_builder& cudf::io::json_writer_options_builder::include_nulls ( bool  val )

inline
