Basic settings
|
Code |
Type in the Java code you want to execute according to the task you need to perform. For further information about Java functions syntax specific to Talend , see Talend Studio Help Contents (Help > Developer Guide > API Reference). For a complete Java reference, check http://docs.oracle.com/javaee/6/api/ Information noteNote: This component offers the advantage of the dynamic schema
feature. This allows you to retrieve unknown columns from source files or
to copy batches of columns from a source without mapping each column
individually. For further information about dynamic schemas, see Dynamic schema.
Information noteNote: If your custom Java code references
org.talend.transform.runtime.api.ExecutionStatus, change it
to
org.talend.transform.runtime.common.MapExecutionStatus.
