=== 6.8.2.4 implemented_interface_info ===

The **implemented_interface_info** structure is defined as follows: 

The items in the **implemented_interface_info** structure are defined as follows: 

**interface** 

The **interface** item has the form of a **class_ref** structure. The **class_ref** structure is defined as part of the **CONSTANT_Classref_info** structure ([[6.7.1_CONSTANT_Classref| Section 6.7.1, CONSTANT_Classref]]). The **interface**_info structure referenced by the **interface** item represents an **interface** implemented by this class. 

**count** 

The **count** item indicates the number of entries in the **index[]** array. 

**index[]** 

The **index[]** item is an array that maps declarations of interface methods to implementations of those methods in this class. It is a representation of the set of methods declared by the interface and its superinterfaces. 

Entries in the index array must be ordered such that the interface method token value ([[4.3.7.7_Interface Methods| Section 4.3.7.7, Interface Methods]]) of the interface method is equal to the index into the array. The interface method token value is assigned to the method within the scope of the interface definition, not within the scope of this class. 

The values in the **index[]** array represent the virtual method tokens ([[4.3.7.6_Virtual Methods| Section 4.3.7.6, Virtual Methods]]) of the implementations of the interface methods. The virtual method token values are defined within the scope of the hierarchy of this class.
