DataKind()

DataKind(string $theValue, mixed $theOperation, boolean $getOld) : mixed

Manage data kind

This method can be used to add, retrieve and delete individual data kind enumerated values; to manage the enumerated set as a whole, use the {@link kTAG_DATA_KIND} offset.

The method expects the following parameters:

• $theValue: This parameter represents the enumerated value we want to manage.
• $theOperation: This parameter identifies the operation:
  • NULL: Return the enumerated value, if it exists, or NULL.
  • FALSE: Delete the enumerated value, if it exists.
  • other: Any other value means that we want to set the enumerated value provided in the previous parameter.
• $getOld: Determines what the method will return:
  • TRUE: Return the value before it was eventually modified.
  • FALSE: Return the value after it was eventually modified.

The method will return either the enumerated value, or NULL if the value was not matched.
