Fiorano eMapper provides an easy to use graphical user interface – the Visual Expression Builder, used for building simple or complex expressions using several predefined functions. All this can be done by performing simple drag-n-drop of required functions, input nodes and connecting them visually.

The Funclet View provided in the Fiorano eMapper Perspective consists of the Visual Expression Builder. The Visual Expression Builder is shown automatically upon clicking on any node in the Output Structure. The Visual Expression Builder consists of two areas:

1. Function palette: A palette listing various functions that can be used while defining mappings between input and output nodes.
2. Funclet easel: A canvas where the user can define mappings by adding functions from the palette and nodes from the input and output trees.

The Funclet View displaying a mapping is shown in the figure below.

Figure 1: Funclet View
The mapping shown in above figure concats the values of two nodes from the input structure ( and ) with some constants ( ) using pre-defined string functions ( ) to obtain the value of a node in the output structure ( ).
A mapping usually has:

1. Destination node
2. Function nodes (optional)
3. Source nodes (optional)

Funclet Easel

The Funclet Easel is the basic work area for creating expression based mappings. The user can place the Function nodes as well as the Source or Destination nodes on this area and make the required mappings.

Source and Destination Nodes

Source Node

The Source node corresponds to a node in the Input Structure Panel. A Source node is shown in the figure below.

Figure 3: Source Node

Destination Node

The Destination node corresponds to a node in the Output Structure Panel. A Destination node is shown in the figure below. 

Figure 4: Destination Node

Adding Link between two Nodes

To make a link between two nodes placed on the Funclet easel, follow the steps below:

1. Click on the gray box on the source building block. A small circle appears, as shown in the figure below. This represents the starting point of the link and the output box of the building block.
   
   
   Figure 5: Source node
    
2. Now drag-and-drop the mouse to the Destination node's input point, which is again represented by a gray box. A big circle appears on the destination node.

Lookup functions

The functions in this category are used to perform the lookup of keyvalue pairs in a database and return the result in sorted fashion.

Description: This function accepts a table name, keyvalue pairs and column names as arguments and does the lookup in the database and returns the result in sorted form.
Input: Table name, Key value pairs, Columns names.
Output: String containing the lookup result in sorted order.
Points to note

• DBLookup fetches the entries from a table and stores them in local cache the first time and it uses this cache to perform lookups for subsequent requests. This cache will not be updated at runtime again. Therefore it should preferably be used only for tables which are not updated once populated, that is for static data.

• Lookup functions take key columns name value pairs as <column1>=<value1>,<column2>=<value2> etc.

  Syntax

  Icon

  White spaces and quotes are not allowed in the name value pair specification above.

Example: dvSendDept=100,dvSendCode=BLK

• Lookup functions can return the values of multiple columns. To get multiple columns, use the format <column3>,<column4>. For Example: dvValueDA, dvDescription
• Dates are expected in MM/dd/yyyy HH:mm:ss format

• Make sure the input value match the column length defined in the database. For example, if the dvSendCode is defined as char(10) in the database, the input value should be BLK followed by seven spaces.

  Icon

  Spaces are not required if you are using MSSQL 2005.

Prerequisites

• For usage and testing in eMapper tool, add required database drivers in the eMapper classpath.

For example, if the lookup tables are in HSQL, include the path of hsqldb.jar in Test Classpath table in the Mapper Preferences page in eStudio.

• To use this function in the eMapper tool, a system property -Dmapper.lookup.dbconfig has to be defined in %FIORANO_HOME%/eStudio/eStudio.ini file and it should point to the path of db.properties file which contains the url, driverName, user and password. Sample db properties file is shown below which contains the data for oracle data base.

Figure 37: Sample db properties file

• For use in Route transformations, mapper.lookup.dbconfig property has to be set in {FIORANOHOME}/fps/bin/fps.conf.
• For use in XSLT component, mapper.lookup.dbconfig property has to be included in JVM_PARAMS For example: -Dmapper.lookup.dbconfig=<path of db.properties>

string regexp:replace(string, string, string, string)
Input: The function accepts four arguments. The first argument is the string to be matched and replaced. The second argument is a regular expression that follows the Javascript regular expression syntax. The fourth argument is the string to replace the matched parts of the string. 
The third argument is a string consisting of character flags to be used by the match. If a character is present then that flag is true. The flags are:

• g: global replace - all occurrences of the regular expression in the string are replaced. If this character is not present, then only the first occurrence of the regular expression is replaced.
• i: case insensitive - the regular expression is treated as case insensitive. If this character is not present, then the regular expression is case sensitive.
