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

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.
