Instance Method Details

#==(other) ⇒ Boolean Also known as: ===

Override the equality test for KdcOptionFlags. Equality is always tested against the #value of the KdcOptionFlags.

Parameters:

  • other (Object) —

    The object to test equality against

Returns:

  • (Boolean) —

    whether the equality test passed

Raises:

  • (ArgumentError) —

    if the other object is not either another KdcOptionFlags or a Integer

#enabled_flag_names ⇒ Array<String>

#include?(flag) ⇒ Boolean

Returns whether the flag is present within the current KdcOptionFlags.

Parameters:
