Constructor Details
- InstagramTagMediaReader
  
  public InstagramTagMediaReader(String accessToken, String clientSecret, String tagName, int maxResults)
  
  Get at most maximum number(maxResults) of recently tagged media.
  
  Parameters:
  
  accessToken - Instagram access token.
  
  clientSecret - Client secret of the registered Instagram app.
  
  tagName - Tag name to search.
  
  maxResults - Maximum number of results to get.
Method Details
- setTagName
  
  public InstagramTagMediaReader setTagName(String tagName)
  
  Sets the tag whose recent media is read; must not be empty and must be set before open().
- getTagName
  
  public String getTagName()
- readImpl
  
  protected Record readImpl() throws Throwable
  
  Description copied from class: DataReader
  Overridden by subclasses to read the next record from this DataReader. The default implementation of DataReader.read() now insures that this method will not be called again after it returns a null.
  If no record is available, null will be returned.
  Contract for subclasses (see also docs/authoring/DataReader.md):
  
  Return null exactly once to signal end-of-stream.
  
  Do not call this method directly — DataReader.read() is the template method that wraps exceptions, increments the record count, and tracks lineage.
  
  Do not call DataEndpoint.incrementRecordCount() here; DataReader.read() already does.
  
  Throw raw exceptions; DataReader.read() wraps them via exception(throwable).
  Specified by:
  
  readImpl in class DataReader
  
  Throws:
  
  Throwable
- open
  
  public void open() throws DataException
  
  Description copied from class: DataEndpoint
  
  Makes this endpoint ready for reading or writing.
  
  Overrides:
  
  open in class IntegrationReader
  
  Throws:
  
  DataException
- close
  
  public void close() throws DataException
  
  Description copied from class: DataEndpoint
  
  Indicates that this endpoint has finished reading or writing.
  
  Overrides:
  
  close in class DataEndpoint
  
  Throws:
  
  DataException
- addExceptionProperties
  
  public DataException addExceptionProperties(DataException exception)
  
  Description copied from class: Endpoint
  
  Adds this endpoint's current state to a DataException. Since this method is called whenever an exception is thrown, subclasses should override it to add their specific information.
  
  Overrides:
  
  addExceptionProperties in class DataReader
