getExpectedVariables

public ExpectedVariables getExpectedVariables(ExpectedVariables... inputVars)

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).

Specified by:

getExpectedVariables in interface LogicalOperator

visit

public void visit(LogicalPlanVisitor visitor)

Specified by:

visit in interface LogicalOperator

toString

public String toString()

Overrides:

toString in class Object
