Description

Class Summary

AccessFlags	Represents a set of method or field access flags, containing permissions and properties of a field or method.
Attribute	Attributes are used in the ClassFile, field_info, method_info, and Code_attribute structures of the class file format.
AttributeCode	The Code attribute is a variable-length attribute used in the attributes table of method_info structures.
AttributeConstantValue	The ConstantValue attribute is a fixed-length attribute used in the attributes table of the field_info structures.
AttributeExceptions	The Exceptions attribute is a variable-length attribute used in the attributes table of a method_info structure.
AttributeInnerClasses	InnerClasses attributes define the encodings of bytecode names of inner classes.
AttributeLineNumberTable	The LineNumberTable attribute is an optional variable-length attribute in the attributes table of a Code attribute.
AttributeLocalVariableTable	The LocalVariableTable attribute is an optional variable-length attribute of a Code attribute.
AttributeSignature	Classfiles need to carry generic type information in a backwards-compatible way.
AttributeSourceFile	The SourceFile attribute is an optional fixed-length attribute in the attributes table of the ClassFile structure.
AttributeSynthetic	Java 1.1 compilers are required, when producing bytecodes, to mark any field or member not directly defined in the source code with an attribute names Synthetic.
AttributeUnknown	An attribute of unknown format.
ClassDataInputStream	A specialized input stream reader for java bytecode files.
ClassDataOutputStream	A specialized output stream writer for java bytecode files.
ClassFile	Represents a java bytecode class file.
Constant	The Constant class represents a single item in the constant pool of a class file.
ConstantClass	The CONSTANT_Class_info structure is used to represent a class or an interface.
ConstantDouble	The CONSTANT_Double_info structure represents eight-byte floating-point numeric constants.
ConstantFieldref	The CONSTANT_Fieldref structure represents a field.
ConstantFloat	The CONSTANT_Float_info structure represents four-byte floating-point numeric constants.
ConstantInteger	The CONSTANT_Integer_info structure represents four-byte integer numeric constants.
ConstantInterfaceMethodref	The CONSTANT_InterfaceMethodref structure represents an interface method.
ConstantLong	The CONSTANT_Long_info structure represents eight-byte integer numeric constants.
ConstantMethodref	The CONSTANT_Methodref structure represents a method.
ConstantNameAndType	The CONSTANT_NameAndType_info structure is used to represent a field or method, without indicating which class or interface type it belongs to.
ConstantString	The CONSTANT_String_info structure is used to represent constant objects of the type java.lang.String.
ConstantUtf8	The CONSTANT_Utf8_info structure is used to represent constant string values.
ConstantValue	The ConstantValue interface provides a standard way for constants to return a wrapped version of their values.
ExceptionTable	Each ExceptionTable object describes one exception handler in the code array of an AttributeCode.
FieldInfo	Each field is described by a variable-length field_info structure.
InnerClass	Each InnerClass object describes one encoded inner class name, its defining scope, its simple name, and a bitmask of the originally declared, untransformed access flags.
LineNumberTable	Each object indicates that the line number in the original Java source file changes at a given point in the code array.
LocalVariableTable	Each object indicates a range of code array offsets within which a local variable has a value.
MethodInfo	Each method, and each instance initialization method <init>, is described by a variable-length method_info structure.

Exception Summary

ClassDataException

Specialized IOException class to handle malformed class files.

Package harpoon.IR.RawClass Description

A representation of the on-disk format of a bytecode file. Contains methods to read and write .class files at a very low-level. Rather awkward to manipulate. No method code representation except a byte-array of java bytecodes.

Use harpoon.IR.Bytecode for analysis at the bytecode level.
