1	DataTable(ObjectSpecification) Returns an empty DataTable for given domain object type, with all properties as columns, excluding mixed-in ones. (For more control on which columns to include, consider a different constructor.)
2	DataTable(ObjectSpecification, Predicate) Returns an empty DataTable for given domain object type, with all (including mixed-in) associations as columns, that pass given columnFilter . If the filter is null it acts as a pass-through.
3	DataTable(ObjectSpecification, Can) Returns an empty DataTable for given domain object type.
4	forDomainType(Class) Returns an empty DataTable for given domain object type, with all properties as columns, excluding mixed-in ones. (For more control on which columns to include, consider #forDomainType(Class, Predicate) or a constructor that fits.)
5	forDomainType(Class, Predicate) Returns an empty DataTable for given domain object type, with all (including mixed-in) associations as columns, that pass given columnFilter . If the filter is null it acts as a pass-through.
6	getLogicalName() Unique within application scope, can act as an id.
7	getElementCount() Count data rows.
8	addDataElementsFrom(DataTable) Adds all data-elements from the other table to this table.
9	setDataElements(Iterable) Sets the data-elements of this table, which make up the rows of this table.
10	setDataElementPojos(Iterable) Sets the data-elements of this table from given pojos, that are adapted to ManagedObject (s).
11	populateEntities() Populates this table from the underlying (default) persistence layer.
12	populateEntities(Query) Populates this table from the underlying (default) persistence layer, using given Query to refine the result.
13	exportToBlob(CollectionContentsExporter) Typical use-case:
