Inherits Taxonomy.
Store a Taxon, i.e., an element in a Taxonomy, with its name, rank, ID and sub-taxa.
This class models a taxon within the hierarchy of a Taxonomy. Each such taxon can have a name assigned to it, a taxonomic rank, an ID, and an arbitrarily nested set of sub-taxa. The name, rank, and ID are free-form strings which can have any value.
The name is one part of a taxonomic path string. For example, given the string
Animalia;Vertebrata;Mammalia;Carnivora
a Taxon could have the name "Mammalia", and contain a Taxon with the name "Carnivora" as child. See Taxonomy for details, see Taxopath for the taxonomic path string format.
Each taxon is itself also a Taxonomy, in terms of class inheritance. This also makes some biological sense, as a taxon can be seen as the taxonomy of its sub-taxa. We however only consider the Taxonomy as the top level of the hierarchy. For more information, see there. The class inheritance is mainly due to software design descisions, in order to make working with Taxonomies and Taxa as easy and straight forward as possible.

Copy constructor.
We need a custom version of this in order to set the Taxon::parent() pointers of all children correctly when copying and to copy the data.
Copying first sets the parent() pointer to nullptr. This is because we might want to get a 'blank' copy, i.e., a Taxon that is not attached to a Taxonomy. This way, the functions expecting a parent pointer don't get a potentially invalid pointer.
If however we copy a Taxon into a Taxonomy (or into some other Taxon), reset_parent_pointers_() is called later anyway, which then sets the parent pointer to the correct value.
Move constructor.
We need a custom version of this in order to set the Taxon::parent() pointers of all children correctly, and to treat the data correctlty when copying.
Virtual implementation function for adding a child taxon.
See Taxonomy::add_child_() for details. In addition to the base class implementation, this function also sets the parent pointer of the Taxon.
Reimplemented from Taxonomy.
| BaseTaxonData const * data_ptr | ( | ) |
| BaseTaxonData const* data_ptr | ( | ) | const |
Return a const pointer to the data.
In most cases, using data<>() is more convenient. However, in some cases, this function might be necessary.
| bool has_data | ( | ) | const |
| std::string const & id | ( | ) | const |
| std::string const & name | ( | ) | const |
| void name | ( | std::string const & | value | ) |
Move assignment operator.
We need a custom version of this in order to set the Taxon::parent() pointers of all children correctly, and to treat the data correctlty when copying.
Copy assignment operator.
We need a custom version of this in order to set the Taxon::parent() pointers of all children correctly, and to treat the data correctlty when copying.
See the move constructor for details.
| Taxon* parent | ( | ) |
Return a pointer to the parent of this taxon, or a nullptr if this is the top level taxon.
| Taxon * parent | ( | ) | const |
| std::string const & rank | ( | ) | const |
| Taxon & reset_data | ( | std::unique_ptr< BaseTaxonData > | data | ) |
Reset the data pointer of this Taxon.
Using this function, a Taxon can be assigend new data. It is also possible to change the data type completely (as long as it derives from BaseTaxonData). Be however aware that many functions that work with a Taxonomy expect a certain data type. Thus, changing it might break those functions and lead to exceptions and other errors.
