Streams_Stream Class

Extends Base_Streams_Stream
Defined in: platform/plugins/Streams/classes/Streams/Stream.php:5
Module: Streams

Class representing 'Stream' rows in the 'Streams' database You can create an object of this class either to access its non-static methods, or to actually represent a stream row in the Streams database.

Methods

__set_state

(
  • $array
)
Streams_Stream

Defined in platform/plugins/Streams/classes/Streams/Stream.php:2002

Implements the __set_state method, so it can work with with var_export and be re-imported successfully.

Parameters:

  • $array Array

Returns:

Streams_Stream:

Class instance

addPermission

(
  • $permissions
)

Defined in platform/plugins/Streams/classes/Streams/Stream.php:739

Parameters:

  • $permissions String

addPreloaded

(
  • $asUserId=null
)

Defined in platform/plugins/Streams/classes/Streams/Stream.php:1795

Add this stream to the list of streams to be preloaded onto the client with the rest of the page

Parameters:

  • $asUserId=null String

    The id of the user from whose point of view the access should be calculated. If this matches the publisherId, just sets full access and calls publishedByFetcher(true). If this is '', only preloads the streams anybody can see. If this is null, the logged-in user's id is used, or '' if no one is logged in

addPreloaded

()

Defined in platform/plugins/Streams/classes/Streams/Stream.php:1810

Remove this stream from the list of streams to be preloaded onto the client with the rest of the page

beforeSave

(
  • $modifiedFields
)
Array

    The array of fields

Returns:

Array:

beforeSet_permissions

(
  • $value
)
Array

Defined in platform/plugins/Streams/classes/Streams/Stream.php:762

Method is called before setting the field and verifies that, if it is a string, it contains a JSON array.

Parameters:

Array:

An array of field name and value

calculateAccess

(
  • $asUserId
  • [$recalculate=false]
  • [$actualPublisherId=null]
  • [$inheritAccess=true]
)
Integer static

Defined in platform/plugins/Streams/classes/Streams/Stream.php:1600

Calculates the access for the current stream by querying the database. Modifies this object, by setting its access levels. After the function returns, you will be able to call the methods testReadLevel(), testWriteLevel() and testAdminLevel() on these streams before using them on the user's behalf.

Parameters:

  • $asUserId String

    Set this to the user relative to whom access is calculated. If this matches the publisherId, just sets full access and calls publishedByFetcher(true). If this is '', only returns the streams anybody can see. If this is null, the logged-in user's id is used, or '' if no one is logged in

  • [$recalculate=false] Boolean optional

    Pass true here to force recalculating access to streams for which access was already calculated

  • [$actualPublisherId=null] String optional

    For internal use only. Used by Streams::isAuthorizedToCreate function.

  • [$inheritAccess=true] String optional

    Set to false to skip inheriting access from other streams, even if specified

Returns:

Integer:

clearAttribute

(

close

(
  • $asUserId
  • [$options=array()]
)
static

Defined in platform/plugins/Streams/classes/Streams/Stream.php:1499

Closes a stream, which prevents anyone from posting messages to it unless they have WRITE_LEVEL >= "close", as well as attempting to remove all relations to other streams. A "cron job" can later go and delete closed streams. The reason you should avoid deleting streams right away is that other subscribers may still want to receive the last messages posted to the stream.

Parameters:

  • $asUserId String

    The id of the user who would be closing the stream

  • [$options=array()] Array optional

    Can include "skipAccess"

displayType

Returns:

String:

Returns the fields and values we can export to clients. Can also contain "messageTotals", "relatedToTotals" and "relatedFromTotals".

Parameters:

  • $options=array() Array
  • [$options.asUserId] String optional

    Defaults to the logged in user, or "" if not logged in If access is not already set for the stream, it will be calculated for $asUserId.

  • [$options.skipAccess=false] String optional

    If true, skips access checks

  • [$options.fields=null] Array optional

    By default, all fields from tables used to "extend" the stream are returned. You can indicate here an array consisting of only the names of fields to export. An empty array means no extended fields will be exported.
