Interface AttributeReader
- public interface AttributeReader
Unknown (non-standard) attributes may be read via user-defined factory
 objects that can be registered with the Attribute.addAttributeReader
 method. These factory objects should implement this interface.

createAttribute
public Attribute createAttribute(int name_index,
                                 int length,
                                 java.io.DataInputStream file,
                                 ConstantPool constant_pool)
- When this attribute reader is added via the static method
     Attribute.addAttributeReader, an attribute name is associated with it.
     As the class file parser parses attributes, it will call various
     AttributeReaders based on the name of the attributes it is
     constructing.
 
- 
- Parameters:
- name_index- An index into the constant pool, indexing a
     ConstantUtf8 that represents the name of the attribute.
- length- The length of the data contained in the attribute.  This
     is written into the constant pool and should agree with what the
     factory expects the length to be.
- file- This is the data input stream that the factory needs to read
     its data from.
- constant_pool- This is the constant pool associated with the
     Attribute that we are constructing.
- Returns:
- The user-defined AttributeReader should take this data and use
     it to construct an attribute.  In the case of errors, a null can be
     returned which will cause the parsing of the class file to fail.
