Detailed Description

Enumeration Type Documentation

capture_groups

enum cudf::strings::capture_groups : uint32_t

strong

Capture groups setting.

For processing a regex pattern containing capture groups. These can be used to optimize the generated regex instructions where the capture groups do not require extracting the groups.

Enumerator
EXTRACT	Capture groups processed normally for extract.
NON_CAPTURE	Convert all capture groups to non-capture groups.

Definition at line 96 of file flags.hpp.

regex_flags

enum cudf::strings::regex_flags : uint32_t

Regex flags.

These types can be or'd to combine them. The values are chosen to leave room for future flags and to match the Python flag values.

Enumerator
DEFAULT	default
MULTILINE	the '^' and '$' honor new-line characters
DOTALL	the '.' matching includes new-line characters
ASCII	use only ASCII when matching built-in character classes
EXT_NEWLINE	new-line matches extended characters
