The File_MARC_List class extends the Structures_LinkedList_Double class to override the key() method in a meaningful way for foreach() iterators.
For the list of File_MARC_Field objects in a File_MARC_Record object, the key() method returns the tag name of the field.
For the list of File_MARC_Subfield objects in a File_MARC_Data_Field object, the key() method returns the code of the subfield.
Located in /MARC/List.php (line 73)
Structures_LinkedList_Double | --File_MARC_List
Returns the tag for a File_MARC_Field object, or the code for a File_MARC_Subfield object.
This method enables you to use a foreach iterator to retrieve the tag or code as the key for the iterator.
