Retrieves a set of logical names for the functions available in the function library.
OrientDB supports the use of functions and user-defined functions, allowing you to do a little bit more on the database side than the standard OrientDB SQL provides. These functions are stored internally as a series of
OFunction instances, but operated on from the Console using their logical names. Using this method, you can retrieve the logical names for all functions defined in the function library.
This method returns a
Set instance that contains a series of
String instances, corresponding to the logical name for each function in the database function library.
