Subinterfaces of ExecutableOperator in se.liu.ida.hefquin.engine.queryplan.executable

Modifier and Type	Interface	Description
interface	BinaryExecutableOp	A specialization of the ExecutableOperator interface that captures executable operators that consume a pair of two sequences of solution mappings (which both are batched into several blocks of solution mappings).
interface	NaryExecutableOp	A specialization of the ExecutableOperator interface that captures executable operators that consume an arbitrary number of sequences of solution mappings (where each such sequence is batched into several blocks of solution mappings).
interface	NullaryExecutableOp	A specialization of the ExecutableOperator interface that captures executable operators that do not consume any input produced by other operators; hence, these operators are the leaf nodes in a tree representation of query execution plans.
interface	UnaryExecutableOp	A specialization of the ExecutableOperator interface that captures executable operators that consume a single input sequence of solution mappings.
