Adding the Extension Function to the MAPexpression.xml File

The expression.xml file defines the functions supported by the Map Editor. To properly reference an extension function in the XML file, you must add an extension function entry to the file.

1. To locate the file, go to: eclipse\plugins\com.nnsy.ebd.eai.internal.tools_version#\grammar\MAPexpressions.xml

2. Reference the fully qualified Java class name for the Extension Function in the MAPexpressions.xml file.

Note: If you have multiple methods defined in a Java class, you must have an entry for each method.

The final step in the process is calling the extension function in a map.
