CodeAttr

public class CodeAttr extends Attribute implements AttrContainer(Code)

Represents the contents of a standard "Code" attribute.

Most of the actual methods that generate bytecode operation are in this class (typically with names starting with emit), though there are also some in Method.

Note that a CodeAttr is an Attribute of a Method, and can in turn contain other Attributes, such as a LineNumbersAttr.
