The only public method of a Flag object is :meth:parse, but it is typically only called by a :class:~absl.flags.FlagValues object. The :meth:parse method is a thin wrapper around the :meth:ArgumentParser.parse()<absl.flags.ArgumentParser.parse> method. The parsed value is saved in .value, and the .present attribute is updated. If this flag was already present, an Error is raised.

:meth:parse is also called during __init__ to parse the default value and initialize the .value attribute. This enables other python modules to safely use flags even if the __main__ module neglects to parse the command line arguments. The .present attribute is cleared after __init__ parsing. If the default value is set to None, then the __init__ parsing step is skipped and the .value attribute is initialized to None.

name the name for this flag
default the default value for this flag
default_unparsed the unparsed default value for this flag.
default_as_str default value as repr'd string, e.g., "'true'" (or None)
value the most recent parsed value of this flag set by :meth:parse
help a help string or None if no help is available
short_name the single letter alias for this flag (or None)
boolean if 'true', this flag does not accept arguments
present true if this flag was parsed from command line flags
parser an :class:~absl.flags.ArgumentParser object
serializer an ArgumentSerializer object
allow_override the flag may be redefined without raising an error, and newly defined flag overrides the old one.
allow_override_cpp use the flag from C++ if available the flag definition is replaced by the C++ flag after init
allow_hide_cpp use the Python flag despite having a C++ flag with the same name (ignore the C++ flag)
using_default_value the flag value has not been set by user
allow_overwrite the flag may be parsed more than once without raising an error, the last set value will be used
allow_using_method_names whether this flag can be defined even if it has a name that conflicts with a FlagValues method.
validators list of the flag validators.

Methods

flag_type

flag_type()

Returns a str that describes the type of the flag.

parse

parse(
    argument
)

Parses string and sets flag value.

Args
argument str or the correct flag value type, argument to be parsed.

serialize

serialize()

Serializes the flag.

unparse

unparse()

__bool__

__bool__()

__eq__

__eq__(
    other
)
