getCEPEngineMonitor
Syntax
getCEPEngineMonitor(engine, subEngineName, [monitorName])
Details
Get a specified or all initial (non-spawned) monitor instances from the specified CEP engine for inspecting their member variables.
Parameters
engine is an engine object or name.
subEngineName is a STRING scalar indicating the name of the CEP sub-engine.
monitorName (optional) is a STRING scalar indicating the monitor name. If not specified, returns all initial monitors.
Returns
A monitor instance, or a dictionary where the key is the monitor name and the value is the monitor instance.
Examples
class mainMonitor:CEPMonitor{
ordersTable :: ANY
def mainMonitor(){
ordersTable = array(ANY, 0)
}
def updateOrders(event) {
ordersTable.append!([event.trader, event.market, event.code, event.price, event.qty])
}
def onload(){
addEventListener(updateOrders, 'Orders',,'all')
}
}
class Orders{
eventTime :: TIMESTAMP
sym :: STRING
val0 :: INT
val1 :: FLOAT
val2 :: DOUBLE
def Orders(s,v0,v1,v2){
sym = s
val0 = v0
val1 = v1
val2 = v2
eventTime = now()
}
}
dummy = table(array(TIMESTAMP, 0) as eventTime, array(STRING, 0) as eventType, array(BLOB, 0) as blobs)
try{dropStreamEngine("cep1")}catch(ex){}
engine=createCEPEngine("cep1",<mainMonitor()>,dummy,Orders,,'eventTime',,,"sym")
