You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: compute_performance.rb
    path of file: ./repos/powerstation/powerstation/IDE_plugin/src/main/resources/static-analyzer/controller_model_analysis
    
    the code of the file until where you have to start completion: def compute_performance(output_dir, start_class, start_function, build_node_list_only=false)
	log_filename = "#{$app_dir}/#{start_class}_#{start_function}.
    
def construct(sliced)
	codes = []
	closures = []
	branches = []
	cur_closure = nil
	cur_branch = nil
	outgoings = []
	cur_instructions = []
	cur_cfg = nil
	set_else = true
	set_end = true
	all_closures = extractClosuresParentNode
	pushed = false
	sliced.each do |s|
		if not s.instance_of?Dataflow_edge and s.getInstr
			instr = s.getInstr
			code = instr.toCode
			pushed = false
			if instr.getClosure and instr.getClosure.parent_instr == instr
				closures.push(s)
				cur_closure = s
				cur_instructions = instr.getClosure.getAllInstrs
				codes.push(code)
				pushed = true
				#next
			end
			if instr.instance_of?Branch_instr
				branches.push(instr)
				cur_branch = instr
				cur_cfg = instr.getBB.getCFG
				outgoings = instr.getBB.getOutgoings
				set_else = true
				puts "outgoings #{outgoings}"
			end
