Method: Warning::Processor#clear

Defined in:
lib/warning.rb

#clear ⇒ Object

Clear all current ignored warnings, warning processors, and duplicate check cache. Also disables deduplicating warnings if that is currently enabled.

If a block is passed, the previous values are restored after the block exits.

Examples:

# Clear warning state
Warning.clear

Warning.clear do
  # Clear warning state inside the block
  ...
end
# Previous warning state restored when block exists
