Here is the documentation for the now deprecated Expression.isNullOrMissing
:
/**
* Creates an IS NULL OR MISSING expression that evaluates whether or not the current
* expression is null or missing.
*
* @return An IS NULL expression.
* @deprecated use Expression.isValued
*/
@Deprecated
@SuppressWarnings("PMD.LinguisticNaming")
@NonNull
public Expression isNullOrMissing() {
return new UnaryExpression(this, UnaryExpression.OpType.Null)
.or(new UnaryExpression(this, UnaryExpression.OpType.Missing));
}
Expression.isNotValued
is the proper function to replace this. Most of the documentation can do some improvement instead of just paraphrasing the function name IMO.
