Java transformation API reference

Java transformation API reference

When you create a Java transformation, you can add API methods to the Java code snippets to define the transformation behavior.
To add an API method to a code snippet, click the
APIs
tab in the Java editor, select the method that you want to add, and click
Add
. Alternatively, you can manually enter the API method in the Java code snippet.
You can add the following API methods to the Java code snippets in a Java transformation:
failSession
Throws an exception with an error message and fails the session.
generateRow
Generates an output row for active Java transformations.
getInRowType
Returns the input type of the current row in the transformation.
incrementErrorCount
Increments the error count for the session.
invokeJExpression
Invokes an expression and returns the value for the expression. Use only in advanced mode..
isNull
Checks for a null value in an input column.
logError
Writes an error message to the session log.
logInfo
Writes an informational message to the session log.
setNull
Sets the value of an output column in an active or passive Java transformation to null.
setOutRowType
Sets the update strategy for output rows. Can flag rows for insert, update, or delete.
