Designing Intelligent Event Processor (IEP) Projects

Data Types in the WSDL Document

The WSDL document defines XSD types (data types). IEP data types, as observable and editable from the property editor for a specific operator, have their counterparts in XSD data types.

For each operator, IEP generates two XSD elements: a regular message object and a batch message object.

Each XSD element contains the following:

Attributes have specific data types and have their equivalent representation in the XSD.

IEP Data Type  

XSD Data Type  

INTEGER 

int 

BIGINT 

long 

DOUBLE 

double 

VARCHAR 

string 

DATE 

date 

TIMESTAMP 

dateTime 

The following types are based on a simple event process that contains a Stream Input operator and a Stream Output operator.
