Modifier and Type	Interface	Description
interface	BinaryLogicalOp	An interface for any type of LogicalOperator that has an arity of two; i.e., it is defined of as a function over two multisets of solution mappings.
interface	NaryLogicalOp	An interface for any type of LogicalOperator that has an arbitrary arity ; i.e., it is defined of as a function over an arbitrary number of multisets of solution mappings.
interface	NullaryLogicalOp	An interface for any type of LogicalOperator that has an arity of zero.
interface	UnaryLogicalOp	An interface for any type of LogicalOperator that has an arity of one; i.e., it is defined of as a function over one multiset of solution mappings.
