Member Function Documentation

get_allow_single_quotes()

CUDF_HOST_DEVICE bool cudf::get_json_object_options::get_allow_single_quotes ( ) const

inline

Returns true/false depending on whether single-quotes for representing strings are allowed.

Returns

true if single-quotes are allowed, false otherwise.

Definition at line 58 of file json/json.hpp.

get_missing_fields_as_nulls()

CUDF_HOST_DEVICE bool cudf::get_json_object_options::get_missing_fields_as_nulls ( ) const

inline

Whether a field not contained by an object is to be interpreted as null.

When set to true, if an object is queried for a field it does not contain, a null is returned.

With missing_fields_as_nulls OFF:
Input  = {"a" : [{"x": "1", "y": "2"}, {"x": "3"}]}
Query  = $.a[*].y
Output = ["2"]
 
With missing_fields_as_nulls ON:
Input  = {"a" : [{"x": "1", "y": "2"}, {"x": "3"}]}
Query  = $.a[*].y
Output = ["2", null]

Returns

true if missing fields are interpreted as null.

Definition at line 113 of file json/json.hpp.

get_strip_quotes_from_single_strings()

CUDF_HOST_DEVICE bool cudf::get_json_object_options::get_strip_quotes_from_single_strings ( ) const

inline

Returns true/false depending on whether individually returned string values have their quotes stripped.

When set to true, if the return value for a given row is an individual string (not an object, or an array of strings), strip the quotes from the string and return only the contents of the string itself. Example:

With strip_quotes_from_single_strings OFF:
Input  = {"a" : "b"}
Query  = $.a
Output = "b"
 
With strip_quotes_from_single_strings ON:
Input  = {"a" : "b"}
Query  = $.a
Output = b

Returns

true if individually returned string values have their quotes stripped.
