The Simple Map Processor Mini-Language performes two primary tasks: validation and conversion. It does this in a context of moving values from one Map to another. The input map will commonly contain Strings, but can contain other object types like Integer, Long, Float, Double, java.sql.Date, Time, and Timestamp.

The path or location for a Simple Method is the classpath and filename of the XML file.


In this Mini-Language you can invoke Simple Map Processors, Services and bsh scripts, perform entity related operations, and create messages to return to the caller. Specific operations can be enclosed in if blocks to execute conditionally and values or fields can be copied around in the maps, lists and method environment.
There are a number of tags which can be used to get and set attributes to/from a request or session object when called as an event or to set attributes in the result when called as a service. These operations are only applied when applicable. In other words if you include an env-to-request operation it will only be invoked when the simple-method is called as an event and an env-to-result operation will only be invoked when the simple-method is called as a service. Everything else is the same when called as an event or a service which makes it easy to write flexible logic that can be mounted/applied in various ways.
There are a number of objects that exist in the method environment when a simple-method starts or that are used as it executes to keep track of certain information. Some will exist when called as an event or a service, these are marked in the XSD. Each name can be overridden using an attribute on the simple-method tag. The defaults are listed below in the XSD.

make-value

remove-by-and

The remove-by-and tag uses the delegator to remove entity values from the datasource and is constrained by anding the fields passed in the map. Make sure the map contains something, or all values will be removed.

clear-cache-line

Uses the delegator to clear elements from the cache; intelligently looks at the map passed to see if it is a byPrimaryKey, and byAnd, or an all.

clear-entity-caches

This is a very simple tag that should be used sparingly because of the performance impact. It clears all lines from all Entity Engine caches. It has no attributes or sub-elements.

set-pk-fields

Looks for each PK field in the named map and if it exists there it will copy it into the named value object.

set-nonpk-fields

Looks for each non-PK field in the named map and if it exists there it will copy it into the named value object.
