Apama Documentation : Developing Apama Applications : EPL Reference : Lexical Elements : Keywords : List of identifiers reserved for future use
List of identifiers reserved for future use
EPL might use the identifiers listed in the table below as keywords in a future release. In this release, if you use one of these reserved words, the correlator logs a warning.
In this table, some identifiers are flagged with an asterisk (*). These identifiers are reserved as keywords only within stream queries. That is, the correlator logs a warning only if you use this identifier inside a stream query. To use one of these identifiers inside a stream query without logging a warning, prefix it with a hash symbol (#). See Escaping keywords to use them as identifiers.
