AIResult

sealed abstract class AIResult extends AnyRef

Encapsulates the result of the abstract interpretation of a method. If the abstract interpretation was cancelled, the result encapsulates the current state of the evaluation which can be used to continue the abstract interpretation later on if necessary/desired.

Abstract Value Members

  1. abstract val cfJoins: BitSet

    The instructions where two or more control flow paths join.

    The instructions where two or more control flow paths join.

    Note

    This information could be recomputed on-demand but is stored for performance reasons.

  2. abstract val code: Code

    The code for which the abstract interpretation was performed.

  3. abstract val domain: Domain

    The domain object that was used to perform the abstract interpretation.

  4. abstract val evaluated: Chain[PC]

    The list of evaluated instructions ordered by the evaluation time; subroutines are identified using the SUBROUTINE marker ids.

  5. abstract val liveVariables: LiveVariables

    The set of statically known live Variables.

  6. abstract val localsArray: Domain.LocalsArray

    The values stored in the registers.

    The values stored in the registers.

    For those instructions that were never executed (potentially dead code if the abstract interpretation succeeded) the locals array will be empty (the value will be null).

  7. abstract val memoryLayoutBeforeSubroutineCall: Chain[(PC, Domain.OperandsArray, Domain.LocalsArray)]

    Contains the memory layout before the call to a subroutine.

    Contains the memory layout before the call to a subroutine. This list is empty if the abstract interpretation completed successfully.

  8. abstract val operandsArray: Domain.OperandsArray

    The array of the operand lists in effect before the execution of the instruction with the respective program counter.

    The array of the operand lists in effect before the execution of the instruction with the respective program counter.

    For those instructions that were never executed (potentially dead code if the abstract interpretation succeeded) the operands array will be empty (the value will be null).

  9. abstract val subroutinesLocalsArray: Domain.LocalsArray

    Contains the memory layout related to the method's subroutines (if any).

    Contains the memory layout related to the method's subroutines (if any).

    Note

    This value is null if the method does not have subroutines (Java 6 and newer class files never contain subroutines) or if no subroutine was analyzed so far.

  10. abstract val subroutinesOperandsArray: Domain.OperandsArray

    Contains the memory layout related to the method's subroutines (if any).

    Contains the memory layout related to the method's subroutines (if any).

    Note

    This value is null if the method does not have subroutines (Java 6 and newer class files never contain subroutines) or if no subroutine was analyzed so far.

  11. abstract def wasAborted: Boolean

    Returns true if the abstract interpretation was aborted.

  12. abstract val worklist: Chain[PC]

    The list of instructions that need to be interpreted next.

    The list of instructions that need to be interpreted next. This list is empty if the abstract interpretation succeed.

    Returns true if the instruction with the given pc was evaluated at least once.

    This operation is much more efficient than performing an exists check on the list of evaluated instructions!
