TransporterSender

This transformer accepts any feature.

Specify how you want to transfer data. The transfer mode must be the same for both the TransporterSender and the TransporterReceiver.

• Stream: Feature data is transferred over the network connection as raw binary data.
• TCP/IP: All feature data will be transferred over the network connection.
• TCP/IP (Attribute): Only the value of a selected attribute is streamed.
• File: The feature data will be saved to disk and the location of the file will be sent over the TCP/IP connection.

The Initiation Sequence specifies which Transporter endpoint is responsible for establishing the Transport stream (ESTABLISH), and which is responsible for connecting (CONNECT).

Note: The workspace that establishes the transfer mode must be running before the connecting workspace. The transfer mode must be consistent if there are multiple transport streams between two workspaces.

This parameter is only needed by the workspace with the Initiation Sequence parameter set to CONNECT, and only when the workspaces are running on different machines.

One of the primary uses for this parameter will be local to a machine in order to partition large workspaces into smaller components that each have their own address space.

Specify either a port number or a service (for example, http, ftp, telnet, imap, gopher, pop3, www, and smtp are services that are typically associated with well-known port numbers).

The default value is 8586.

This parameter is only used when Transfer Mode is set to File.  It specifies the base file name to use.  

Each file that is created will have a -<integer> appended to the end of the name to keep all files unique.  

Example: If the File Name is features.fft, the first file created is features-0.fft, the second file created is features-1.fft, and so on. The full path of the file will be passed to the receiver and the receiver must be able to access the file from the same path (drive letter included).

This parameter is only used when Transfer Mode is set to File. It specifies how many features to write to a file before sending the location of the file to the receiver.

This parameter specifies the name of the output attribute. It is required only when the Transfer Mode is set to TCP/IP (Attribute).

Using the Text Editor

The Text Editor provides a convenient way to construct text strings (including regular expressions) from various data sources, such as attributes, parameters, and constants, where the result is used directly inside a parameter.

Using the Arithmetic Editor

The Arithmetic Editor provides a convenient way to construct math expressions from various data sources, such as attributes, parameters, and feature functions, where the result is used directly inside a parameter.

Conditional Values

Set values depending on one or more test conditions that either pass or fail.

Content

Expressions and strings can include a number of functions, characters, parameters, and more.

When setting values - whether entered directly in a parameter or constructed using one of the editors - strings and expressions containing String, Math, Date/Time or FME Feature Functions will have those functions evaluated. Therefore, the names of these functions (in the form @<function_name>) should not be used as literal string values.

Content Types

String Functions	These functions manipulate and format strings.
Special Characters	A set of control characters is available in the Text Editor.
Math Functions	Math functions are available in both editors.
Date/Time Functions	Date and time functions are available in the Text Editor.
Math Operators	These operators are available in the Arithmetic Editor.
FME Feature Functions	These return primarily feature-specific values.
FME Parameters	FME and workspace-specific parameters may be used.
Creating and Modifying User Parameters	Create your own editable parameters.

Note: Not all tools are available in all transformers.
