Class Main class structure. Holds information about a class. Everything is stored in native order with the exception of the of attributes. They are stored big-endian inside their AttributeContainer. @minor_version: Minor version of the class file specification. @major_version: Major version of the class file specification. @constant_pool: The constant pool. @access_flags: A 16-bit access flag. @interfaces_count: The number of interfaces implemented by the class. @interfaces: An array with the constant pool indices of the ClassEntry entries for the interfaces implemented by the class. @fields_count: The number of fields in the class. @fields: An array with the fields in this class. @methods_count: The number of methods in this class. @methods: An array with the method in this class. @attributes_count: The number of attributes for this class. @attributes: An array with the attributes for this class. The first 4 bytes of every java class file. Mask for public visibility. Mask for private visibility. Mask for protected visibility. Mask for static. Mask for final. Mask for synchronized. The flag is always set for classes but it has a different meaning. It was used to indicate that the class has a super class which is of course always the case except for java.lang.Object. It is there for compatibility with 1.1 or older VMs. So you should ignore it in the context of classes. Mask for volatile. Mask for transient. Mask for native. Mask for interface. Mask for abstract. Mask to indicate that strict IEEE-754 floating point behavior is required. @filename: @classpath: @Returns: @bootclasspath: @data: @Returns: @classfile: @Returns: @javaclass: @javaclass: @Returns: @javaclass: @Returns: @javaclass: @Returns: @javaclass: @Returns: @class_struct: @Returns: @javaclass: @Returns:
