Class Twitter

java.lang.Object
  winterwell.jtwitter.Twitter

public class Twitter
extends java.lang.Object

Java wrapper for the Twitter API version 1.3.3

Example usage:

        // Make a Twitter object
        Twitter twitter = new Twitter("my-name","my-password");
        // Print Winterstein's status
        System.out.println(twitter.getStatus("winterstein"));
        // Set my status
        twitter.updateStatus("Messing about in Java");

See http://www.winterwell.com/software/jtwitter.php for more information about this wrapper. See http://apiwiki.twitter.com/Twitter-API-Documentation for more information about the Twitter API.

Notes:

• This wrapper takes care of all url-encoding/decoding.
• This wrapper will throw a runtime exception (TwitterException) if a methods fails, e.g. it cannot connect to Twitter.com or you make a bad request. I would like to improve error-handling, and welcome suggestions on cases where more informative exceptions would be helpful.

Perform a search of Twitter.

Warning: the User objects returned by a search (as part of the Status objects) are dummy-users. The only information that is set is the user's screen-name and a profile image url. This reflects the current behaviour of the Twitter API. If you need more info, call show(String) with the screen name.

This supports maxResults and pagination. A language filter can be set via setLanguage(String) TODO parameters: geocode: Optional. Returns tweets by users located within a given radius of the given latitude/longitude, where the user's location is taken from their Twitter profile. The parameter value is specified by "latitude,longitude,radius", where radius units must be specified as either "mi" (miles) or "km" (kilometers). Note that you cannot use the near operator via the API to geocode arbitrary locations; however you can use this geocode parameter to search near geocodes directly.

Parameters:

searchTerm -

callback - an object whose process() method will be called on each new page of results.

the - number of results to fetch per page

Returns:

search results - up to maxResults / rpp if maxResults is positive, or rpp if maxResults is negative.

Returns:

your retweet

search

public java.util.List<Twitter.Status> search(java.lang.String searchTerm)

Wrapper for search(String, ICallback, int) with no callback and fetching 100 results.

Perform a search of Twitter.

Warning: the User objects returned by a search (as part of the Status objects) are dummy-users. The only information that is set is the user's screen-name and a profile image url. This reflects the current behaviour of the Twitter API. If you need more info, call show(String) with the screen name.

This supports maxResults and pagination. A language filter can be set via setLanguage(String) TODO parameters: geocode: Optional. Returns tweets by users located within a given radius of the given latitude/longitude, where the user's location is taken from their Twitter profile. The parameter value is specified by "latitude,longitude,radius", where radius units must be specified as either "mi" (miles) or "km" (kilometers). Note that you cannot use the near operator via the API to geocode arbitrary locations; however you can use this geocode parameter to search near geocodes directly.

Parameters:

searchTerm -

Returns:

search results - up to maxResults + rpp if maxResults is positive, or rpp if maxResults is negative.

TwitterException

setMaxResults

public void setMaxResults(int maxResults)

Parameters:

maxResults - if greater than zero, requests will attempt to fetch as many pages as are needed! -1 by default, in which case most methods return the first 20 statuses/messages.

If setting a high figure, you should usually also set a sinceId or sinceDate to limit your Twitter usage. Otherwise you can easily exceed your rate limit.

setPageNumber

public void setPageNumber(java.lang.Integer pageNumber)

Parameters:

pageNumber - null (the default) returns the first page. Pages are indexed from 1. This is used once only! Then it is reset to null

setSinceDate

public void setSinceDate(java.util.Date sinceDate)

Date based filter on statuses and messages. This is done client-side as Twitter have - for their own inscrutable reasons - pulled support for this feature.

If using this, you probably also want to increase setMaxResults(int) - otherwise you get at most 20, and possibly less (since the filtering is done client side).

Parameters:

sinceDate -

setUntilDate

public void setUntilDate(java.util.Date untilDate)

Parameters:

untilDate - the untilDate to set

getUntilDate

public java.util.Date getUntilDate()

Parameters:

statusId -

setSource

public void setSource(java.lang.String sourceApp)
