\JTableObserverTags

Abstract class defining methods that can be implemented by an Observer class of a JTable class (which is an Observable).

Attaches $this Observer to the $table in the constructor.
The classes extending this class should not be instanciated directly, as they
are automatically instanciated by the JObserverMapper

Hierarchy

Extends

• JTableObserver

Members

protected

• $newTags — array
  Override for postStoreProcess param newTags, Set by setNewTags, used by onAfterStore and onBeforeStore
• $replaceTags — boolean
  Override for postStoreProcess param replaceTags. Set by setNewTags, used by onAfterStore
• $table — JTable
  The observed table
• $tagsHelper — JHelperTags
  Helper object for managing tags
• $typeAliasPattern — string
  The pattern for this table's TypeAlias

public

• $_myTableForPregreplaceOnly — JTableObserverTags
  Not public, so marking private and deprecated, but needed internally in parseTypeAlias for PHP < 5.4.0 as it's not passing context $this to closure function.

Methods

protected

• parseTypeAlias() — Internal method Parses a TypeAlias of the form "{variableName}.type", replacing {variableName} with table-instance variables variableName Storing result into $this->tagsHelper->typeAlias

public

• createObserver() — Creates the associated observer instance and attaches it to the $observableObject Creates the associated tags helper class instance $typeAlias can be of the form "{variableName}.type", automatically replacing {variableName} with table-instance variables variableName
• onAfterStore() — Post-processor for $table->store($updateNulls) You can change optional params newTags and replaceTags of tagsHelper with method setNewTagsToAdd
• onBeforeDelete() — Pre-processor for $table->delete($pk)
• onBeforeStore() — Pre-processor for $table->store($updateNulls)
• setNewTags() — Sets the new tags to be added or to replace existing tags

Inherited from JTableObserver

public

• onAfterDelete() — Post-processor for $table->delete($pk)
• onAfterLoad() — Post-processor for $table->load($keys, $reset)
• onAfterStore() — Post-processor for $table->store($updateNulls)
• onBeforeDelete() — Pre-processor for $table->delete($pk)
• onBeforeLoad() — Pre-processor for $table->load($keys, $reset)
• onBeforeStore() — Pre-processor for $table->store($updateNulls)
