=== 6.8.2.1 interface_info and class_info shared Items ===

**flags** 

The **flags** item is a mask of modifiers used to describe this interface or class. Valid values are shown in the following table: 

Name 

Value 

ACC_INTERFACE 

0x8 

ACC_SHAREABLE 

0x4 

ACC_REMOTE 

0x2 

The **ACC_INTERFACE** flag indicates whether this ****interface_info**** or **class_info** structure represents an interface or a class. The value must be one if it represents an ****interface_info**** structure and zero if a **class_info** structure. 

The **ACC_SHAREABLE** flag in an interface_info structure indicates whether this interface is shareable. The value of this flag must be one if and only if the interface is **javacard.framework.Shareable** interface or extends that interface directly or indirectly. 

The **ACC_SHAREABLE** flag in a **class_info** structure indicates whether this class is shareable.<SUP>[7]</SUP> The value of this flag must be one if and only if this class or any of its superclasses implements an interface that is shareable. 

The **ACC_REMOTE** flag indicates whether this class or interface is remote. The value of this flag must be one if and only if the class or interface satisfies the requirements defined in [[2.2.6.1_Remote Classes and Remote Interfaces| Section 2.2.6.1, Remote Classes and Remote Interfaces]].  

All other flag values are reserved. Their values must be zero. 

**interface_count** 

The **interface_count** item of the **interface_info** structure indicates the number of entries in the **superinterfaces[]** table item. The value represents the number of direct and indirect superinterfaces of this interface. Indirect superinterfaces are the set of superinterfaces of the direct superinterfaces. Valid values are between 0 and 14, inclusive. 

The **interface_count** item of the **class_info** structure indicates the number of entries in the interfaces table item. The value represents the number of interfaces implemented by this class, including superinterfaces of those interfaces and potentially interfaces implemented by superclasses of this class. Valid values are between 0 and 15, inclusive.
