    • hasVariables

      boolean hasVariables()

    • getVariables

      Collection<IEVar> getVariables()

    • getVariable

      IEVar getVariable(long offset)

    • canClearNativeStack

      boolean canClearNativeStack(long addressBegin, long addressEnd)

    • clearNativeStack

      void clearNativeStack(long addressBegin, long addressEnd)

    • createStackItem

      IEVar createStackItem(long preferredOffset, int preferredBitsize)
      Create a new stack variable. May return null, may be at different offset and/or with a different size. The IEVar created may be larger than the actual hit size!! eg, native item is int64, on a 32-bit slot stack. A corresponding native stack item will be created. This method may fail if existing native items conflict with the requested creation.
      Parameters:
      preferredOffset - relative stack offset in bytes
      preferredBitsize - requested variable size in bits - must be a multiple of 2
      Returns:
      the IEVar, null on error

    • createPureStackItem

      IEVar createPureStackItem(long offset, int bitsize)
      Create a pure IEVar, regardless of a referenced native stack.
      Parameters:
      offset -
      bitsize -
      Returns:

    • getActualStackItemType

      IWildcardType getActualStackItemType(long offset)
      Parameters:
      offset -
      Returns:
