  • Method Details

    • refresh

      protected boolean refresh()
      Description copied from class: DatabaseObject
      Tells the object to refresh its state from the database.
      Specified by:
      refresh in class DatabaseObject

      true if the object was able to refresh itself. Return false if the object was deleted. Objects that extend this class must implement a refresh method. If an object can never refresh itself, then it should always return false.

    • addReference

      public void addReference(Address refAddr, int opIndex)
      Description copied from interface: Equate
      Add a reference (at the given operand position) to this equate. If a reference already exists for the instruction at this address, then the old reference will be removed before the new reference is added.
      Specified by:
      addReference in interface Equate
      Parameters:
      refAddr - the address where the equate is used.
      opIndex - the operand index where the equate is used.

    • addReference

      public void addReference(long dynamicHash, Address refAddr)
      Description copied from interface: Equate
      Add a reference (at the given dynamic hash position) to this equate. If a reference already exists for the instruction at this address, then the old reference will be removed before the new reference is added.
      Specified by:
      addReference in interface Equate
      Parameters:
      dynamicHash - constant varnode dynamic hash value
      refAddr - the address where the equate is used.
