Package gnu.bytecode
Class CodeAttr
java.lang.Object
gnu.bytecode.Attribute
gnu.bytecode.CodeAttr
- All Implemented Interfaces:
AttrContainer
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
Attribute
s, such as a LineNumbersAttr
.
