Field Detail

class_index

public int class_index

The value of the class_index item must be a valid index into the constant_pool table of the parent. The constant_pool entry at that index must be a CONSTANT_Class_info structure representing the class or interface type that contains the declaration of the field.

The class_index item of a CONSTANT_Fieldref must be a class type, not an interface type.

name_and_type_index

public int name_and_type_index

The value of the name_and_type_index item must be a valid index into the constant_pool table of the parent. The constant_pool entry at that index must be a CONSTANT_NameAndType_info structure. This constant_pool entry indicates the name and descriptor of the field.
