Description copied from interface: LogicalOperator

Returns the variables that can be expected in the solution mappings produced by this operator if the input(s) to this operator contain solutions mappings with the given set(s) of variables. The number of ExpectedVariables objects passed to this method must be in line with the degree of this operator (e.g., for a unary operator, exactly one such object must be passed).

toString

public String toString()

Overrides:
