Package org.apache.bcel.verifier.structurals

Provides a PassVerifier class mostly used internally by JustIce, yielding a control flow graph for public use as a nice side effect.

          Description

Interface Summary
InstructionContext An InstructionContext offers convenient access to information like control flow successors and such.
Subroutine This interface defines properties of JVM bytecode subroutines.
 

Class Summary
ControlFlowGraph This class represents a control flow graph of a method.
ExceptionHandler This class represents an exception handler; that is, an ObjectType representing a subclass of java.lang.Throwable and the instruction the handler starts off (represented by an InstructionContext).
ExceptionHandlers This class allows easy access to ExceptionHandler objects.
ExecutionVisitor This Visitor class may be used for a type-based Java Virtual Machine simulation.
Frame This class represents a JVM execution frame; that means, a local variable array and an operand stack.
GenericArray A placeholder class that can be used to create an ObjectType of which has some of the properties arrays have.
InstConstraintVisitor A Visitor class testing for valid preconditions of JVM instructions.
LocalVariables This class implements an array of local variables used for symbolic JVM simulation.
OperandStack This class implements a stack used for symbolic JVM stack simulation.
Pass3bVerifier This PassVerifier verifies a method of class file according to pass 3, so-called structural verification as described in The Java Virtual Machine Specification, 2nd edition.
Subroutines Instances of this class contain information about the subroutines found in a code array of a method.
UninitializedObjectType This class represents an uninitialized object type; see The Java Virtual Machine Specification, Second Edition, page 147: 4.9.4 for more details.

Package Specification

Contained in this package is a PassVerifier class for use with the JustIce verifier and its utility classes. Only the pass performing what Sun calls "Structural Constraints on Java Virtual Machine Code" has a PassVerifier class here. JustIce calls this pass "Pass 3b".
