ODatabaseDocument - createEdgeClass()

This method creates a database class, which extends the E class on the database.

Creating Edge Classes

OrientDB borrows from the Object Oriented programming paradigm the concept of classes, which in these Reference pages is called a database class, to avoid confusion with classes in Java. Internally, each database class is an instance of OClass. Using this method, you can create new database classes on the database, which extend the E edge class.

To create a vertex class instead, see createVertexClass().

Syntax

default OClass ODatabaseDocument().createEdgeClass(String name)

Return Value

This method returns an OClass instance for the new database class.
