Lowlevel Bytecode Manipuation

Description

Interface Summary

ConstantEntry	Interface implemented by Entries representing constant values to generically access/mutate the constant value.
Entry	Base interface for all constant pool entries.
LowLevelConstants	Interface to track constants used in lowlevel bytecode.

Class Summary

ClassEntry	Low-level representation of a constant pool entry describing a Class.
ComplexEntry	The complex entry serves as a base class for field, method, and interface method constant pool entries.
ConstantPool	Represents a class constant pool, containing entries for all strings, constants, classes, etc referenced in the class structure and opcodes.
DoubleEntry	Representation of a constant double value in the constant pool.
FieldEntry	Represents a reference to a class field.
FloatEntry	Represents a constant float value in the constant pool.
IntEntry	Represents a constant int value in the constant pool.
InterfaceMethodEntry	Represents an interface method in the constant pool.
LongEntry	Represnts a long constant in the constant pool.
MethodEntry	Represents a method in the constant pool.
NameAndTypeEntry	Constant pool entry containing indexes referencing a name and a type.
PlaceHolderEntry	The PlaceHolderEntry is inserted into the constant pool after LongEntries and DoubleEntries to maintain the proper indexing, as these types take up 2 indeces in the constant pool.
StringEntry	String constant constant pool entry.
UTF8Entry	A constant pool entry representing a unicode string value.

Package com.techtrader.modules.tools.bytecode.lowlevel Description

Lowlevel Bytecode Manipuation

This package contains facilities for lowlevel bytecode manipulation through the class constant pool. It is generally not necessary to use this package directly, as all necessary bytecode manipulation functionality is made available at a high level via the com.techtrader.modules.tools.bytecode package.

Notable Classes

• Class ConstantPool

  A class constant pool. Maintains a list of Entries referenced in the class, using a hashing scheme to avoid duplicate entries and to search the entries quickly.

• Interface Entry

  Base interface for all constant pool entry types.

• Class PlaceHolderEntry

  Long and Double constant pool entries take up two index spots in the pool, but they are treated as single objects in the Entry list. To maintain proper indexing, a PlaceHolderEntry is inserted after each Long/DoubleEntry as the .class file is read.
