public class TypeFrameModelingVisitor extends AbstractFrameModelingVisitor<org.apache.bcel.generic.Type,TypeFrame> implements org.apache.bcel.Constants, Debug
Visitor to model the effects of bytecode instructions on the types of the values (local and operand stack) in Java stack frames. This visitor does not verify that the types are sensible for the bytecodes executed. In other words, this isn't a bytecode verifier, although it wouldn't be too hard to turn it into something vaguely verifier-like.

  • Method Details

    • setValueNumberDataflow

      public void setValueNumberDataflow(ValueNumberDataflow valueNumberDataflow)
      Set ValueNumberDataflow for the method being analyzed. This is optional; if set, we will use the information to more accurately model the effects of instanceof instructions.
      Parameters:
      valueNumberDataflow - the ValueNumberDataflow

      public void setLocalTypeTable(org.apache.bcel.classfile.LocalVariableTypeTable localTypeTable)

    • isInstanceOfFollowedByBranch

      public boolean isInstanceOfFollowedByBranch()
      Return whether an instanceof instruction was followed by a branch. The TypeAnalysis may use this to get more precise types in the resulting frame.
      Returns:
      true if an instanceof instruction was followed by a branch, false if not

    • getInstanceOfType

      public org.apache.bcel.generic.Type getInstanceOfType()
      Get the type of the most recent instanceof instruction modeled. The TypeAnalysis may use this to get more precise types in the resulting frame.
      Returns:
      the Type checked by the most recent instanceof instruction

    • getInstanceOfValueNumber

      public ValueNumber getInstanceOfValueNumber()
      Get the value number of the most recent instanceof instruction modeled. The TypeAnalysis may use this to get more precise types in the resulting frame.
      Returns:
      the ValueNumber checked by the most recent instanceof instruction

    • setFieldStoreTypeDatabase

      public void setFieldStoreTypeDatabase(FieldStoreTypeDatabase database)
      Set the field store type database. We can use this to get more accurate types for values loaded from fields.
      Parameters:
      database - the FieldStoreTypeDatabase

    • getDefaultValue

      public org.apache.bcel.generic.Type getDefaultValue()
      Description copied from class: AbstractFrameModelingVisitor
      Produce a "default" value. This is what is pushed onto the stack by the handleNormalInstruction() method for instructions which produce stack values.
      Specified by:
      getDefaultValue in class AbstractFrameModelingVisitor<org.apache.bcel.generic.Type,TypeFrame>

    • analyzeInstruction

      public void analyzeInstruction(org.apache.bcel.generic.Instruction ins) throws DataflowAnalysisException
      Description copied from class: AbstractFrameModelingVisitor
      Analyze the given Instruction.
      Overrides:
      analyzeInstruction in class AbstractFrameModelingVisitor<org.apache.bcel.generic.Type,TypeFrame>
      Parameters:
      ins - the Instruction
      Throws:
      DataflowAnalysisException - if an error occurs analyzing the instruction; in most cases, this indicates that the bytecode for the method being analyzed is invalid

    • startBasicBlock

      public void startBasicBlock()
      This method must be called at the beginning of modeling a basic block in order to clear information cached for instanceof modeling.

    • consumeStack

      protected void consumeStack(org.apache.bcel.generic.Instruction ins)
      Consume stack. This is a convenience method for instructions where the types of popped operands can be ignored.

    • pushValue

      protected void pushValue(org.apache.bcel.generic.Type type)
      Work around some weirdness in BCEL (inherited from JVM Spec 1): BCEL considers long and double types to consume two slots on the stack. This method ensures that we push two types for each double or long value.

    • pushReturnType

      protected void pushReturnType(org.apache.bcel.generic.InvokeInstruction ins)
      Helper for pushing the return type of an invoke instruction.

    • modelNormalInstruction

      public void modelNormalInstruction(org.apache.bcel.generic.Instruction ins, int numWordsConsumed, int numWordsProduced)

      Overrides:
      modelNormalInstruction in class AbstractFrameModelingVisitor<org.apache.bcel.generic.Type,TypeFrame>
      Parameters:
      ins - the Instruction to model
