7.2.9 RepresentsClause Attribute

This atribute describes a “represents” clause, saying what is the meaning of a particular model field. It has the following structure:

     RepresentsClause_attribute {
       u2 attribute_name_index;
       u4 attribute_length;
       u2 access_flags;
       expression_info field;
       expression_info spec;
     }

The meaning of the fields is as follows:

• attribute_name_index - index in the constant pool of the attribute name (org.bmlspecs.RepresentsClause)
• attribute_length - length in bytes of the whole structure
• access_flags - the flags that are set for the clause. 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.
• field - the field described by the “represents” clause
• spec - the expression specifying the field

The field must be an expression referering to a model field defined in the class or its superclass.
