Method Detail

init

protected io.siddhi.core.util.snapshot.state.StateFactory init(io.siddhi.core.executor.ExpressionExecutor[] attributeExpressionExecutors,
                                                               io.siddhi.core.util.config.ConfigReader configReader,
                                                               io.siddhi.core.config.SiddhiQueryContext siddhiQueryContext)

The initialization method for FunctionExecutor, which will be called before other methods and validate the all configuration and getting the initial values.

Specified by:

init in class io.siddhi.core.executor.function.FunctionExecutor

Parameters:

attributeExpressionExecutors - are the executors of each attributes in the Function

configReader - this hold the FunctionExecutor extensions configuration reader.

siddhiQueryContext - Siddhi query context

Specified by:

execute in class io.siddhi.core.executor.function.FunctionExecutor

Parameters:

data - null if the Function parameter count is zero or runtime data value of the Function parameter

Returns:

the Function result

getReturnType

public io.siddhi.query.api.definition.Attribute.Type getReturnType()

return a Class object that represents the formal return type of the method represented by this Method object.
