Class Details

[line 45]
Interface for data sources that may contain explicit null values

getValue() was designed to return null for missing values, unfortunately that led to bugs when data source contained values explicitly set to null, see http://pear.php.net/bugs/bug.php?id=20295. This interface defines a method that may be used by elements to check whether a value is available, even if that value is null.
