SPEC java.security.AlgorithmParameters

OBJECTS
	java.lang.String algorithm;
	java.security.spec.AlgorithmParameterSpec paramSpec;
	byte[] params; 
	java.lang.String format;
	byte[] encParams;

EVENTS
	g1: getInstance(algorithm);
	g2: getInstance(algorithm, _);
	Get := g1 | g2;

	i1: init(paramSpec);
	i2: init(params);
	i3: init(params, _);
	Init := i1 | i2 | i3;
    
	e1: encParams = getEncoded();
	e2: encParams = getEncoded(format);
	GetEncoded := e1 | e2;

ORDER
	Get, Init, GetEncoded?
