Tweeter

Upon successful completion of a status update, the feature will be output through the Tweet output port, and will have several new attributes:

_twitter_response: Contains the JSON response text from the server. The value of this attribute can be explored using the JSONFragmenter or JSONExtractor transformers.

_twitter_status_id: Contains the integer ID of the status update.

_twitter_status_truncated: Contains a Boolean string indicating whether or not the status update had to be trimmed to 140 characters.

Error

If a status update could not be sent, the feature will be output through the Error output port, and will have the following new attributes:

_twitter_response: If a response was received from the Twitter server, it will be stored in this attribute.

_twitter_error: If the Twitter response contained an error message, it will be stored in this attribute.

Text	This parameter can be used to enter a status update directly, or to enter the name of an attribute which contains the status update.
Include Geometry	If this parameter is set to Yes, the tweet will be tagged with the center point of the feature’s geometry. This will result in the feature geometry being reprojected to LL84, if it is not already in an equivalent coordinate system.
Image Files	This parameter allows up to four images to be attached to the tweet. The images must be less than 5 MB, and must be PNG, JPEG, GIF or WEBP files.

How to Set Parameter Values

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters.

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.

Text Editor

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.

Arithmetic Editor

Conditional Values

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

Parameter Condition Definition Dialog

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.

Dialog Options - Tables

Table Tools

Transformers with table-style parameters have additional tools for populating and manipulating values.

Row Reordering

Enabled once you have clicked on a row item. Choices include:

Add a row
Remove a row
Move current row up one
Move current row down one
Move current row to top
Move current row to bottom

Cut, Copy, and Paste

Enabled once you have clicked on a row item. Choices include:

Cut a row - delete and copy to clipboard
Copy a row to the clipboard
Paste a row from the clipboard

Cut, copy, and paste may be used within a transformer, or between transformers.

Filter

Start typing a string, and the matrix will only display rows matching those characters. Searches all columns. This only affects the display of attributes within the transformer - it does not alter which attributes are output.

Import

Import populates the table with a set of new attributes read from a dataset. Specific application varies between transformers.

Reset/Refresh

Generally resets the table to its initial state, and may provide additional options to remove invalid entries. Behavior varies between transformers.

Note: Not all tools are available in all transformers.

Processing Behavior	Feature-Based
Feature Holding	No
Dependencies	None
Aliases	TwitterStatusUpdater
