Function hasSubset

hasSubset<EntityT, ParamT, ReturnT>(subset: CollectionField<EntityT, any, any, boolean, boolean> | CollectionFilterFunction<EntityT, ReturnT> | ParamT[], set: CollectionField<EntityT, any, any, boolean, boolean> | CollectionFilterFunction<EntityT, ReturnT> | ParamT[]): BooleanFilterFunction<EntityT>
Build a filter function to test whether a set is a subset of the other, i.e. whether the second parameter can be transformed into the first by reordering and / or removing items. Evaluates to boolean.

Returns
The newly created filter function.
Type Parameters
- EntityT extends Entity<EntityT>
- ParamT extends FilterFunctionPrimitiveParameterType
- ReturnT
Parameters
- subset: CollectionField<EntityT, any, any, boolean, boolean> | CollectionFilterFunction<EntityT, ReturnT> | ParamT[]
  
  The subset to test for. This can either be an array, a reference to a field or another filter function.
- set: CollectionField<EntityT, any, any, boolean, boolean> | CollectionFilterFunction<EntityT, ReturnT> | ParamT[]
  
  The set to test. This can either be an array, a reference to a field or another filter function.
Returns BooleanFilterFunction<EntityT>
