OFunction - isIdempotent()

Determines whether the function is idempotent.

Function Idempotence

OrientDB differentiates between idempotent queries and non-idempotent commands. That is, queries that always return the same results versus commands that write to the database. In functions this is indicated by a simple boolean value set on the OFunction instance. Using this method, you can check whether the function has been designated as idempotent. To set idempotence for the function, see the setIdempotent() method.

Syntax

boolean OFunction.isIdempotent()

Return Type

This method returns a boolean instance. A value of true indicates that the function is idempotent and only reads from the database. A value of false indicates that the function is non-idempotent and modifies data on the database.
