SchemaStatisticalPopulation class
A StatisticalPopulation is a set of instances of a certain given type
that satisfy some set of constraints. The property SchemapopulationType
is used to specify the type. Any property that can be used on instances
of that type can appear on the statistical population. For example, a
SchemaStatisticalPopulation representing all SchemaPersons with a
SchemahomeLocation
of East Podunk California would be described by
applying the appropriate SchemahomeLocation
and SchemapopulationType
properties to a SchemaStatisticalPopulation item that stands for that
set of people. The properties SchemanumConstraints
and
SchemaconstraintProperty
are used to specify which of the populations
properties are used to specify the population. Note that the sense of
"population" used here is the general sense of a statistical population,
and does not imply that the population consists of people. For example, a
SchemapopulationType
of SchemaEvent or SchemaNewsArticle could be
used. See also SchemaObservation, where a SchemapopulationType
such
as SchemaPerson or SchemaEvent can be indicated directly. In most
cases it may be better to use SchemaStatisticalVariable instead of
SchemaStatisticalPopulation.

Properties
- additionalType ↔ String?

getter/setter pair
- alternateName ↔ String?
-
An alias for the item.
getter/setter pair
- description ↔ dynamic
-
A description of the item.
getter/setter pair
- disambiguatingDescription ↔ String?
-
A sub property of description. A short description of the item used to
disambiguate from other, similar items. Information from other properties
(in particular, name) may be necessary for the description to be useful
for disambiguation.
getter/setter pair
- hashCode → int
-
The hash code for this object.
no setterinherited
- identifier ↔ dynamic
-
The identifier property represents any kind of identifier for any kind of
SchemaThing, such as ISBNs, GTIN codes, UUIDs etc. Schema.org provides
dedicated properties for representing many of these, either as textual
strings or as URL (URI) links. See background
notes for more details.
getter/setter pair
- image ↔ dynamic
-
An image of the item. This can be a
SchemaURL
or a fully described SchemaImageObject.getter/setter pair - mainEntityOfPage ↔ dynamic
-
Indicates a page (or other CreativeWork) for which this thing is the main
entity being described. See background
notes for details.
getter/setter pair
- name ↔ String?
-
The name of the item.
getter/setter pair
- populationType ↔ SchemaClass?
-
Indicates the populationType common to all members of a
SchemaStatisticalPopulation or all cases within the scope of a
SchemaStatisticalVariable.
getter/setter pair
- potentialAction ↔ SchemaAction?
-
Indicates a potential Action, which describes an idealized action in
which this thing would play an 'object' role.
getter/setter pair
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- sameAs ↔ String?
-
URL of a reference Web page that unambiguously indicates the item's
identity. E.g. the URL of the item's Wikipedia page, Wikidata entry, or
official website.
getter/setter pair
- subjectOf ↔ dynamic
-
A CreativeWork or Event about this Thing.
getter/setter pair
- url ↔ String?
-
URL of the item.
getter/setter pair
Methods

inherited
-
toJsonLd(
) → Map< String, dynamic> - Serialize SchemaStatisticalPopulation to JSON-LD
-
toString(
) → String -
A string representation of this object.
