Using variables

EPL supports the use of variables in monitors. Depending on where in the monitor you declare a variable, that variable is global or local:

Global — Variables declared in monitors and not inside actions or events are global variables. Global variables are in monitor scope.

Local — Variables declared inside actions are local variables. Local variables are in action scope.

A variable can be of any of the following types: boolean, decimal, float, integer, string, action, context, dictionary, event, listener, location, sequence or stream. For details about these types, see Types in the Apama EPL Reference. Information about variables is presented in the following topics:
