Name and Notes page

Name and Notes

Exporter information may include:

Settings	Description
Name	The unique name of the exporter object. You can edit the Name. Echoview assigns a default name when an exporter is created or when Reset is used. Notes: In Echoview, name-uniqueness affects objects. Existing EV files, that contain objects with the same name, will open and affected objects will be assigned a unique name. Valid names for dataflow objects consist of supported characters. These can include text and symbol character encoding and international characters. Commas, double quotes, the vertical bar and the Tab key press are unsupported characters. Where a name is used as the basis of an export file name, any unsupported file name characters are automatically removed.
Dynamic name	Select Dynamic to use a name that updates when an Exporter Property updates. Dynamic names have text that contain property names within braces, that are based on Command interface property names. The Properties Information window displays supported Command interface property names. Suitable property names are those that have numeric or text value. A Dynamic name may be specified through the Console. When Dynamic is selected, the Name property becomes read-only under the Command interface and the dataflow object. Example: Dynamic name is Sv integrate for the domain [{AnalysisDomain}] for an Sv Integration analysis exporter object. Figure 1 shows the exporter object Dynamic name when the Analysis Domain property is specified as Regions. Figure 2 shows the change in the displayed Dynamic name when Analysis Domain is changed to Transects. Figure 1. Figure 2. Notes: Refer to Console Property option DynamicName.
Reset	Resets the name to the default name generated for a new exporter object.

Notes

A text box in which you can enter extra information about the exporter.
