Property Ioss::NullEntity::get_implicit_property ( const std::string & my_name ) const

inlinevirtual

Calculate and get an implicit property.

These are calcuated from data stored in the EntityBlock instead of having an explicit value assigned. An example would be 'element_block_count' for a region. Note that even though this is a pure virtual function, an implementation is provided to return properties that are common to all 'block'-type grouping entities. Derived classes should call 'GroupingEntity::get_implicit_property' if the requested property is not specific to their type.

Implements Ioss::GroupingEntity.
