Get variables

For example, you can specify: ${java.io.tmpdir}/hop/tempfile.txt and it will be expanded to /tmp/hop/tempfile.txt on Unix-like systems.

See also the Set Variables transform. To convert the Variable into a data type other than String use Select Values - Meta Data tab. To get system values, including command line arguments, use the Get System Info transform.

All fields of this transform support metadata injection. You can use this transform with ETL Metadata Injection to pass metadata to your pipeline at runtime.
