Input/Output expressions

I/O expressions are used to process multiple input or output documents in a single map.

I/O expressions can be used to:
  • Read from and write to multiple data sources.
  • Specify the location from which the data should be read or to which it should be written.
  • Switch to a different representation within a map.

These expressions are only allowed in elements that inherit from other structures.

The following examples illustrate some use cases for these expressions.
