class	SolutionMappingsHashTable	This is a hash table based implementation of invalid reference SolutionMappingsIndex that can be used for indexes that are meant to be used for cases in which adding and probing into the index may not happen concurrently.
class	SolutionMappingsHashTableBasedOnOneVar	This is a hash table based implementation of invalid reference SolutionMappingsIndex that can be used for indexes that are built on one query variable and that are meant to be used for cases in which adding and probing into the index may not happen concurrently.

Uses of StatsProvider in se.liu.ida.hefquin.engine.queryplan.executable

Subinterfaces of StatsProvider 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	ExecutableOperator	An executable operator provides the implementation of the concrete algorithm that a physical operator is associated with.
interface	ExecutablePlan
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.
