    • Method Detail

      • getObject

        Object getObject​(IdentityIF identity)
        INTERNAL: Returns a handle for the specified value. Use this method when you do not know the the object value is. The handle can be used in the other methods to access information about the object. NOTE: an exception is thrown when the identity is unknown.

      • getIdentity

        IdentityIF getIdentity​(Object object)
        INTERNAL: Returns the identity of the specified object handle.

      • getType

        Class<?> getType​(Object object)
        INTERNAL: Returns the type of the specified object handle. Note that this method returns the same value as getIdentity(object).getType().

      • isDirty

        boolean isDirty​(Object object)
        INTERNAL: Returns true if the specified object is dirty.

      • isDirty

        boolean isDirty​(Object object,
                int field)
        INTERNAL: Returns true if the specified object field is dirty.

      • nextDirty

        int nextDirty​(Object object,
              int start)
        INTERNAL: Returns the index of the next dirty field from and including the start index. Method returns -1 if there are no dirty fields.

      • nextDirty

        int nextDirty​(Object object,
              int start,
              int end)
        INTERNAL: Returns the index of the next dirty field from and including start, up until end, but not including end. Method returns -1 if there are no more dirty fields.

      • setDirtyFlushed

        void setDirtyFlushed​(Object object,
                     int field)
        INTERNAL: Marks the dirty fields as being flushed (stored in the database).
