public abstract class DoubleCriterion
extends NumericCriterion

A type double numeric search criterion.

A double numeric criterion is a numeric criterion where the attribute value is of type double.

Each double numeric criterion class offers constructors of the following forms, where T is the type of the criterion:

T (double val)

Creates a criterion that exactly matches val.

T (Double val)

Creates a criterion that exactly matches val.

T (double start, double end)

Creates a criterion for the range start through end inclusive.

T (Double start, double end)

Creates a criterion for the range start through end inclusive.

T (double start, Double end)

Creates a criterion for the range start through end inclusive.

T (Double start, Double end)

Creates a criterion for the range start through end inclusive.

T (DoubleRange... ranges)

Creates a criterion for a vararg list or array of DoubleRange ranges.

T (Collection<DoubleRange> ranges)

Creates a criterion for a collection of DoubleRange ranges.

The start and/or end of a range may be null, in which case no constraint is placed on the start and/or end. See NumericCriterion for details and examples.

An empty or "no-op" criterion that matches any value can be constructed with a null value, with start and end values both of which are nll, or with an empty array or collection of ranges.
