These fields have different meanings according to what a given item represents. Note: Statements in brackets denote a type, e.g. [Class] means an item of type org.deepjava.classItems.Class.

• index: Used to number interfaces, which contain methods called by invokeinterface.
• offset: Not used, always -1.
• address: Contains the absolute address of the type descriptor (field size).

• index: Not used, always -1.
• offset: Offset in bytes of the type descriptor in the memory segment.
• address: Contains the absolute address of the array type descriptor.

• index: If instance method → index into method table (starting with 0), if class method → always -1. index is set by the Class File Reader.
• offset: Offset in bytes of the method starting from the start address of the code of the class of this method.
• address: Contains the absolute address of the method.
