Class Quantifier.Physical

java.lang.Object

com.apple.foundationdb.record.query.plan.temp.Quantifier

com.apple.foundationdb.record.query.plan.temp.Quantifier.Physical

All Implemented Interfaces:

Bindable, Correlated<Quantifier>

Enclosing class:

Quantifier

public static final class Quantifier.Physical
extends Quantifier

Physical quantifier. This kind of quantifier is the conduit between two RecordQueryPlans. It does not have any associated semantics; all semantics and execution details must be subsumed by the query plans themselves.

Method Detail

getRangesOver

@Nonnull
public ExpressionRef<? extends RecordQueryPlan> getRangesOver()

Description copied from class: Quantifier

Return the reference that the quantifier ranges over.

Specified by:

getRangesOver in class Quantifier

Returns:

ExpressionRef this quantifier ranges over

getRangesOverPlan

@Nonnull
public RecordQueryPlan getRangesOverPlan()

getShorthand

@Nonnull
public String getShorthand()

Description copied from class: Quantifier

Return a short hand string for the quantifier. As a quantifier's semantics is usually quite subtle and should not distract from expressions. For example, when a data flow is visualized the returned string should be short.

Specified by:

getShorthand in class Quantifier

Returns:

a short string representing the quantifier.

equals

public boolean equals(Object other)

Overrides:

equals in class Quantifier

hashCode

public int hashCode()

Overrides:

hashCode in class Quantifier

structuralEquals

public boolean structuralEquals(@Nullable
                                Object other)

structuralHashCode

public int structuralHashCode()

toString

@Nonnull
public String toString()

Overrides:

toString in class Quantifier

rebase

@Nonnull
public Quantifier.Physical rebase(@Nonnull
                                  AliasMap translationMap)

Description copied from interface: Correlated

Rebases this and all other objects this objects is composed of using a given translation map.

Parameters:

translationMap - a map defining a translation from CorrelationIdentifiers ids to CorrelationIdentifiers ids'. After the rebase, every correlation to an id contained ids that is contained or referred to directly or indirectly by this must have been transformed to use the mapped counterpart of id id' in ids'. IDs not contained in the translation map must remain unmodified by the rebase operation.

Returns:

a new entity that has been rebased

computeFlowedValues

@Nonnull
public Optional<List<? extends QuantifiedColumnValue>> computeFlowedValues()

Specified by:

computeFlowedValues in class Quantifier
