TIBCO BusinessEvents® Enterprise Edition 6.3.1

# Custom Functions

Using TIBCO BusinessEvents you can define custom functions and expose them as catalog functions or mapper functions. By exporting the project containing the custom Java functions to a project library, the custom Java functions can be used in other projects.

To use custom functions in the mapper, set the property `com.tibco.datamodel.xml` to `true` in the CDD file. This property must be set to true to force XPath or XSLT to use XML rather than the new JSON native data model. If your incoming or outgoing messages are exclusively XML based, setting this property to true avoids conversions from a separate internal data model to XML and use XML natively.

When the `com.tibco.datamodel.xml` property is true, set the property `be.serialization.notation=standard` to print numbers in decimal or standard format. For example, to print number 3.0.
But if the property `be.serialization.notation` is not set or `be.serialization.notation=scientific` (default value), then the numbers are serialized in scientific format. For example, to print 34.45E1.
