7.2.7 Constraint Attribute

This attribute describes the history constraints of the class. It has the following structure:

     Constraint_attribute {
       u2 attribute_name_index;
       u4 attribute_length;
       u2 access_flags;
       formula_info constraint;
     }

The meaning of the fields is as follows:

• attribute_name_index - index in the constant pool of the attribute name (org.bmlspecs.Constraint)
• attribute_length - length in bytes of the whole structure
• access_flags - the flags that are set for the constraint. The only allowed flags are ACC_PUBLIC, ACC_PROTECTED, ACC_PRIVATE and ACC_STATIC. Only one of ACC_PUBLIC, ACC_PROTECTED, ACC_PRIVATE can be set. All other flags must be cleared.
• constraint - the binary representation of the constraint formula.
