Output Port Writing

Some Writers allow you to write data to the optional output port.

Below is the list of Writers allowing output port writing:


The attributes for the output port writing in these components may be defined using the URL File Dialog.

Set the File URL attribute of the Writer to port:$0.FieldName[:processingType].

Here processingType is optional and can be set to one of the following: discrete or stream. If it is not set explicitly, it is discrete by default.

If you connect the optional output port of any Writer with an edge to another component, metadata of the edge must contain the specified FieldName of string, byte or cbyte data type.

When a graph runs, data is read through the input according to the input metadata, processed by the Writer according to the specified processing type and sent subsequently to the other component through the optional output port of the Writer.
