This software tool allows for easy cross-referencing between different items or data sets. Its flexibility and versatility make it a go-to choice for various industries and applications.
To create an object, you can utilize the following code:
```
use Bio::Root::Object;
$myObj->xref($object_ref);
```
This module provides accessors to aid in object manipulation. These accessors include:
- "obj()" which retrieves the cross-referenced object.
- "desc()" which provides a description of the cross-reference relevance.
- "set_desc()" which sets the cross-reference's description.
- "type()" which identifies whether a relationship is symmetrical or asymmetrical.
Additionally, there is a method available that can remove all cross-references within the Xref object, but it is not implemented yet.
Bio::Root::Xref is capable of managing sets of objects that are not necessarily related through composition or inheritance; instead, these objects have an arbitrary criterion set by the client. Currently, Bio::Root::Xref inherits from both Bio::Root::Object.pm, and Bio::Root::Vector.pm.
An Xref object is a heterogenous Vector object example since the objects in the vector can derive from different base classes. Cross-referenced objects in Bio::Root::Xref create a symmetrical relationship with each other. However, it is important to note that this relationship is not necessarily transitive, meaning an xref of B and B is an xref of C doesn't mean that A is necessarily an xref of C. Asymmetrical xrefs are also possible.
Bio::Root::Object.pm manages the establishment of cross-references, which can be seen by utilizing the "xref()" method in that module. It's important to note that the API for this module is still under development, and it is not currently complete. Therefore, it is advised that the developers use the module judiciously.
