- provides a summary hash of classes used and their associated object names.
The HashTable representation allows us to leverage various HashTable
methods. This hashed summary view can be useful when querying
particular aspects, but is most useful when reducing the objects in
consideration to a particular subset. For example,
const wordHashSet interestingTypes
{
volScalarField::typeName,
volVectorField::typeName
};
IOobjectList objects(runTime, runTime.timeName());
HashTable<wordHashSet> classes = objects.classes();
classes.retain(interestingTypes);
// Or do just the opposite:
classes.erase(unsupportedTypes);
Can also use the underlying HashTable filter methods
STYLE: use templated internals to avoid findString() when matching subsets
