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.

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".

Interface Summary

Interface	Description
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

Class	Description
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.
