The Get Variables transform allows you to get the value of a variable and
create field(s) from it or allows you to add values to existing input rows. You
could consider it to be a "Set fields” transform. It can retrieve the value of
a previous variable and/or retrieves previous rows or you can set static values
to a variable or input rows. You only need to use this transform if you need
the variable value in a field.
-
Note that workflow/environment variables are set only once. A pipeline needs
to start to get any new variables. A running or sequential or nested (nested
pipelines are technically the same pipeline) pipeline can't fetch new variable
values. A pipeline is considered started when a pipeline starts for every row
in a pipeline executor.
+You can always refer to variables/parameters using the syntax: ${myVariable},
for example from a previous pipeline.

${openvar}java.io.tmpdir{closevar}/hop/tempfile.txt and it will be expanded to
/tmp/hop/tempfile.txt on Unix-like systems.

To convert the Variable into a data type other than String use Select Values -
Meta Data tab.
