tf.compat.v1.flags.FlagHolder

Holds a defined flag.

tf.compat.v1.flags.FlagHolder(
    flag_values: tf.compat.v1.flags.FlagValues,
    flag: Flag[_T],
    ensure_non_none_value: bool = False
)

This facilitates a cleaner api around global state. Instead of::

flags.DEFINE_integer('foo', ...)
flags.DEFINE_integer('bar', ...)

def method():
  # prints parsed value of 'bar' flag
  print(flags.FLAGS.foo)
  # runtime error due to typo or possibly bad coding style.
  print(flags.FLAGS.baz)

it encourages code like::

_FOO_FLAG = flags.DEFINE_integer('foo', ...)
_BAR_FLAG = flags.DEFINE_integer('bar', ...)

def method():
  print(_FOO_FLAG.value)
  print(_BAR_FLAG.value)

since the name of the flag appears only once in the source code.

Args
