Hierarchy

Extends

• JTable

Members

protected

• $_autoincrement — boolean
  Indicates that the primary keys autoincrement.
• $_db — JDatabaseDriver
  JDatabaseDriver object.
• $_errors — array
  An array of error messages or Exception objects.
• $_locked — boolean
  Indicator that the tables have been locked.
• $_observers — JObserverUpdater
  Generic observers for this JTable (Used e.g. for tags Processing)
• $_rules — JAccessRules
  The rules associated with this record.
• $_tbl — string
  Name of the database table to model.
• $_tbl_key — string
  Name of the primary key field in the table.
• $_tbl_keys — array
  Name of the primary key fields in the table.
• $_trackAssets — boolean
  Should rows be tracked as ACL assets?

public

• $convertToInt — array
  Array of object fields to convert to integers before calculating SHA1 hash. Some values are stored differently when an item is created than when the item is changed and saved. This works around that issue.
• $ignoreChanges — array
  Array of object fields to unset from the data object before calculating SHA1 hash. This allows us to detect a meaningful change in the database row using the hash. This can be read from the #__content_types content_history_options column.

Methods

public

• __construct() — Constructor
• deleteOldVersions() — Utility method to remove the oldest versions of an item, saving only the most recent versions.
• getHashMatch() — Utility method to get a matching row based on the hash value and id columns.
• getSha1() — Utility method to get the hash after removing selected values. This lets us detect changes other than modified date (which will change on every save).
• store() — Overrides JTable::store to set modified hash, user id, and save date.

Inherited from JTable

protected

• _getAssetName() — Method to compute the default name of the asset.
• _getAssetParentId() — Method to get the parent asset under which to register this one.
• _getAssetTitle() — Method to return the title to use for the asset table. In tracking the assets a title is kept for each asset so that there is some context available in a unified access manager. Usually this would just return $this->title or $this->name or whatever is being used for the primary name of the row. If this method is not overridden, the asset name is used.
• _lock() — Method to lock the database table for writing.
• _unlock() — Method to unlock the database table for writing.

public

• addIncludePath() — Add a filesystem path where JTable should search for table class files.
• appendPrimaryKeys() — Method to append the primary keys for this table to a query.
• attachObserver() — Implement JObservableInterface: Adds an observer to this instance.
• bind() — Method to bind an associative array or object to the JTable instance.This method only binds properties that are publicly accessible and optionally takes an array of properties to ignore when binding.
• check() — Method to perform sanity checks on the JTable instance properties to ensure they are safe to store in the database. Child classes should override this method to make sure the data they are storing in the database is safe and as expected before storage.
• checkIn() — Method to check a row in if the necessary properties/fields exist. Checking a row in will allow other users the ability to edit the row.
• checkOut() — Method to check a row out if the necessary properties/fields exist. To prevent race conditions while editing rows in a database, a row can be checked out if the fields 'checked_out' and 'checked_out_time' are available.
• delete() — Method to delete a row from the database table by primary key value.
• getDbo() — Method to get the JDatabaseDriver object.
• getFields() — Get the columns from database table.
• getInstance() — Static method to get an instance of a JTable class if it can be found in the table include paths. To add include paths for searching for JTable classes see JTable::addIncludePath().
• getKeyName() — Method to get the primary key field name for the table.
• getNextOrder() — Method to get the next ordering value for a group of rows defined by an SQL WHERE clause.
• getObserverOfClass() — Gets the instance of the observer of class $observerClass
• getPrimaryKey() — Get the primary key values for this table using passed in values as a default.
• getRules() — Method to get the rules for the record.
• getTableName() — Method to get the database table name for the class.
• hasPrimaryKey() — Validate that the primary key has been set.
• hit() — Method to increment the hits for a row if the necessary property/field exists.
• isCheckedOut() — Method to determine if a row is checked out and therefore uneditable by a user. If the row is checked out by the same user, then it is considered not checked out -- as the user can still edit it.
• load() — Method to load a row from the database by primary key and bind the fields to the JTable instance properties.
• move() — Method to move a row in the ordering sequence of a group of rows defined by an SQL WHERE clause.
• publish() — Method to set the publishing state for a row or list of rows in the database table. The method respects checked out rows by other users and will attempt to checkin rows that it can after adjustments are made.
• reorder() — Method to compact the ordering values of rows in a group of rows defined by an SQL WHERE clause.
• reset() — Method to reset class properties to the defaults set in the class definition. It will ignore the primary key as well as any private class properties (except $_errors).
• save() — Method to provide a shortcut to binding, checking and storing a JTable instance to the database table. The method will check a row in once the data has been stored and if an ordering filter is present will attempt to reorder the table rows based on the filter. The ordering filter is an instance property name. The rows that will be reordered are those whose value matches the JTable instance for the property specified.
• setDBO() — Method to set the JDatabaseDriver object.
• setRules() — Method to set rules for the record.
• store() — Method to store a row in the database from the JTable instance properties.

Inherited from JObject

public

• __toString() — Magic method to convert the object to a string gracefully.
• def() — Sets a default value if not alreay assigned
• get() — Returns a property of the object or the default value if the property is not set.
• getError() — Get the most recent error message.
• getErrors() — Return all errors, if any.
• getProperties() — Returns an associative array of object properties.
• set() — Modifies a property of the object, creating it if it does not already exist.
• setError() — Add an error message.
• setProperties() — Set the object properties based on a named array/hash.
