TCPIPReceiver

Features containing the data that has been received are output through this port.

The Initiation Sequence specifies whether the transformer is responsible for establishing the connection (Establish), or connecting to an establishing host (Connect). If the TCPIPReceiver is used with a corresponding TCPIPSender, either the sender or receiver can be the establisher.

Note: The workspace that establishes the transfer mode must be running before the connecting workspace.

This parameter is only needed by the workspace with the Initiation Sequence parameter set to Connect. The TCPIPReceiver in Connect mode can connect to the specified host and listen for data. The establishing host can be another FME workspace, or any application or server that communicates over TCP/IP.

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.

If this parameter is set to No, the TCPIPReceiver will only accept one connection to receive features from. Otherwise the TCPIPReceiver will accept new client connections if the current client has disconnected until the translation is stopped.

If this parameter is set to Fixed Data Length, then each feature output by the TCPIPReceiver will contain a maximum number of bytes, specified by the Data Length parameter. This method is intended for receiving data that always has a fixed length.

If this parameter is set to Receive Data Length from Sender, then the TCPIPReceiver will expect to receive the size of incoming data before the data payload, up to a maximum of 256KB per request. In this way, the value of Data Length is determined dynamically by the sender, rather than set at a fixed value by the receiver. If the sender transmits more than 256KB, then the output data will be divided into 256KB segments. If the TCPIPReceiver is used in conjunction with a TCPIPSender, then the TCPIPSender should have the Send Data Length attribute set to Yes. If this parameter is set to No, then the TCPIPReceiver processes all incoming transmissions as raw data.

If this parameter is set to Custom Delimiter, then the TCPIPReceiver will split received data into features using the specified Delimiter parameter, up to a maximum of 256KB per feature.

Specify the maximum number of bytes that the transformer receives before it outputs a feature. In the event that the connection is terminated, the transformer will output any remaining data. If -1 is entered as a value for this parameter, then the TCPIPReceiver will receive up to 256KB per request. Only used if Delimiting Method is set to Fixed Data Length.

Specify the string that separates the received data into segments. Each segment will become a separate feature. For example, if Delimiter was the string “__”, then the data “ABC__DEF__GHI” would be split into 3 features with Output Attribute values of “ABC”, “DEF”, and “GHI” respectively.

Specify the output attribute that will store the received data.

Specifies the destination attribute for the number of bytes received by the TCPIPReceiver.

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.

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.
