Javassist (Java programming assistant) makes bytecode engineering simple. It is a class library for editing bytecode in Java; it enables Java programs to define a new class at runtime and to modify a given class file when the JVM loads it.
The most significant class of this package is
See the description of this class first.
To know the version number of this package, type the following command:
java -jar javassist.jar
It prints the version number on the console.
ByteArrayClassPathcontains bytes that is served as a class file to a
ClassPool.Thrown when bytecode transformation has failed.A search-path for obtaining a class file by
java.lang.Class.A hash table associating class names with different names.
ClassPathis an interface implemented by objects representing a class search path.A container of
CtClassobjects.Simple translator of method bodies (also see the
javassist.exprpackage).Interface containing the method names to be used as array access replacements.Default implementation of the
ArrayAccessReplacementMethodNamesinterface giving default values for method names to be used for replacing accesses to array elements.
CtBehaviorrepresents a method, a constructor, or a static constructor (class initializer).An instance of
CtClassrepresents a class.An instance of CtConstructor represents a constructor.An instance of CtField represents a field.Instances of this class specify how to initialize a field.An instance of
CtMemberrepresents a field, a constructor, or a method.An instance of
CtMethodrepresents a method.Instances of this class represent a constant parameter.A collection of static methods for creating a
CtConstructor.A collection of static methods for creating a
CtMethod.An instance of
CtPrimitiveTyperepresents a primitive type.The class loader for Javassist.A simpler class loader.A class search-path representing a class loader.The Modifier class provides static methods and constants to decode class and member access modifiers.Signals that something could not be found.Utility for calculating serialVersionUIDs for Serializable classes.An observer of
Loader.A class search-path specified with URL (http).
