The code you type inside the UDJC step is pure Java. Therefore, the fields of your Transformation will be seen as Java objects according to the following equivalence table:
|
Data type in PDI |
Java Class |
|
String |
Java.lang.String |
|
Integer |
Java.lang.Long |
|
Number |
Java.lang.Double |
|
Date |
Java.util.Date |
|
BigNumber |
BigDecimal |
|
Binary |
byte[] |
The opposite occurs when you create an object inside the Java code and want to expose it as a new field of your Transformation. For example, in the Java code, if you define a long variable in the Fields tab, you have to define the correspondent output field as Integer.
