==== 5.6.2 CONSTANT_Classref ====

The **CONSTANT_Classref_info** structure is used to represent a class or interface: 

The items of the **CONSTANT_Classref_info** structure are the following: 

**tag** 

The tag item has the value of **CONSTANT_Classref** (7). 

**name_index** 

The value of the **name_index** item must be a valid index into the **constant_pool** table. The **constant_pool** entry at that index must be a **CONSTANT_Utf8_info** ([[5.6.4_CONSTANT_Utf8| Section 5.6.4, CONSTANT_Utf8]]) structure representing a valid fully qualified Java class or interface name. This name is fully qualified since it may represent a class or interface defined in a package other than the one described in the export file. 

As in Java class files, ASCII periods (`.') that normally separate the identifiers in a class or interface name are replaced by ASCII forward slashes (`/'). For example, the interface name **javacard.framework.Shareable** is represented in a **CONSTANT_Utf8_info** structure as **javacard/framework/Shareable**.
