On APEX 4.1No, that is all of the API documentation. It may be unintentionally incomplete (i.e. documentation bugs), but some APIs are intentionally not documented as they are intended only for internal APEX use. Oracle may change the signatures, behaviour, or implementation of these undocumented and unsupported methods, or remove them completely without notice. Use of undocumented APIs by developers may result in loss of data, and/or failure of your applications, APEX installation or database. Oracle may not provide support in cases where damage has occurred as a consequence of using undocumented/unsupported features.
I wonder if there is a reference documenation to show all the available built-in functions?
