5. 1 + 3 + goal state and operators with unary inertia encoded
6. 1 + actions, initial and goal state after expansion of variables
7. 1 + final domain representation

Parameters:

level - the trace level.

getTraceLevel

public final int getTraceLevel()

Returns the trace level.

Returns:

level the trace level.
