| Class | Description |
|---|---|
| Analyzer |
A data-flow analyzer that determines the type state of the stack and local
variable table at every reachable instruction in a method.
|
| ControlFlow |
Represents the control flow graph of a given method.
|
| ControlFlow.Block |
Basic block.
|
| ControlFlow.Catcher |
Represents a catch clause.
|
| ControlFlow.Node |
A node of (post) dominator trees.
|
| Executor |
Executor is responsible for modeling the effects of a JVM instruction on a frame.
|
| Frame |
Represents the stack frame and local variable table at a particular point in time.
|
| FramePrinter |
A utility class for printing a merged view of the frame state and the
instructions of a method.
|
| MultiArrayType |
Represents an array of
MultiType instances. |
| MultiType |
MultiType represents an unresolved type.
|
| Subroutine |
Represents a nested method subroutine (marked by JSR and RET).
|
| SubroutineScanner |
Discovers the subroutines in a method, and tracks all callers.
|
| Type |
Represents a JVM type in data-flow analysis.
|
| Util |
A set of common utility methods.

This package provides an API for performing data-flow analysis on a method's bytecode.
This allows the user to determine the type state of the stack and local variable table
at the start of every instruction. In addition this API can be used to validate
bytecode, find dead bytecode, and identify unnecessary checkcasts.
Look at ControlFlow class first for details.
The users of this package must know the specifications of class file and Java bytecode. For more details, read this book:
Javassist, a Java-bytecode translator toolkit.
