public record IndexDirective(String keyExpr, List<String> indexExprs, String oneIf)
extends Record

@index(by: varOrVarArray[, expr: exprOverVars]) The idea is to allow ordering by a given list of variables, and have a separate expression for the effective output. This may help a DBMS by not having to order by the final expression.

keyExpr - the value for the keyExpr record component

indexExprs - the value for the indexExprs record component

oneIf - the value for the oneIf record component

Method Details

toString

public final String toString()

Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

a hash code value for this object

equals

public final boolean equals(Object o)

Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).

Specified by:

o - the object with which to compare

Returns:

true if this object is the same as the o argument; false otherwise.

keyExpr

public String keyExpr()

Returns the value of the keyExpr record component.

Returns:

the value of the keyExpr record component

indexExprs
