  • Field Details

    • DIRECT_ON_SET

      protected static final Object DIRECT_ON_SET
      If value==DIRECT_ON_SET, break indirection on a set.
    • INDIRECT_FLUIDS

      protected static final Object INDIRECT_FLUIDS
      If value has this value, force indirection even for the setWithSave operation. Ignoring the restore aspect of a fluid-let, it is normally treated as closer to a define than to a set, in that we break the sharing with another Environment. Setting value to INDIRECT_FLUIDS means we do not want to break the indirection in this case.
    • base

      protected Location<T> base
      If non-null, operations are forwarded to the base location.
    • value

      protected Object value
      If base is null, the current value stored in this Location. If base is non-null, then value is generally ignored. However, the special value DIRECT_ON_SET means that writes change value directly, instead of setting the value of base.
