The data type Integer can be defined as a whole number without a decimal place. When a platform/application demands a specific value in integer, the Cast: Integer mapper can be deployed.
Here is how to do it!
Step 1: Click on Add Data Transformer.
Step 2: Select Value Mapper.
Step 3: Select Key Accessor from the Accessor drop-down menu.
Step 4: Click on Add Keys and specify the key (or keys) that you wish to map from an entity data.
Step 5: Click on Add Mappers and select Cast: Integer.
Step 6: On clicking the Run Test button, you will see that the Cast: Integer mapper has mapped the specified key (or keys) to Integer values accordingly.
