end

#merge_into_self(others) ⇒ void

This method returns an undefined value.

Given an array of Parlour::RbsGenerator::Extend instances, merges them into this one. This particular implementation will simply do nothing, as instances are only mergeable if they are indentical. You MUST ensure that #mergeable? is true for those instances.

Parameters:

# File 'lib/parlour/rbs_generator/extend.rb', line 79

def merge_into_self(others)
  # We don't need to change anything! We only merge identical extends
end

#mergeable?(others) ⇒ Boolean

Given an array of Parlour::RbsGenerator::Extend instances, returns true if they may be merged into this instance using #merge_into_self. This is always false.

Parameters:

Returns:

  • (Boolean) —

    Whether this instance may be merged with them.
