TwitterStatusFetcher

Upon successful completion of the request, the transformer will output a new feature for each tweet in the timeline. Each output feature will contain several attributes:

_tweet_id: The identification number of the tweet.

_tweet_status: The text of the tweet.

_tweet_created_at: The date and time of the status update. This will be formatted in the standard FME date/time format: YYYYMMDDHHMMSS

_tweet_username: The screen name of the user who created the tweet.

_tweet_search_result: The JSON text of the status update. This can be further examined via the JSONFragmenter and JSONExtractor transformers.

If a request could not be completed, the feature will be output through the Error output port, and will have the following new attributes:

_twitter_search_result: 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.

Select the type of timeline to fetch. The transformer can fetch a user timeline, or a list timeline.

When fetching a user timeline, use this parameter to enter the user whose updates are to be retrieved. When fetching a list timeline, use this parameter to enter the name of the list. This attribute may be set to an attribute value.

When fetching a list timeline, use this parameter to enter the name of the twitter user that owns the list being fetched.

When fetching a list timeline, this parameter may be used to filter out re-tweets. If it is set to ‘Yes’, the output may contain re-tweets. If the parameter is set to ‘No’, re-tweets will be removed from the transformer results.

The maximum number of tweets to be returned. Note that twitter may return fewer tweets than this number.

All user timeline requests require a valid twitter username and password.

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.
