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

Definition at line 37 of file flags.hpp.
