Class TypedValue<T>

  • All Implemented Interfaces:
    ShortDumpable
    public class TypedValue<T>
extends Object
implements ShortDumpable
    Value and definition pair. E.g. used in expression variable maps. We need to have explicit type here. It may happen that there will be variables without any value. But we need to know the type of the variable to compile the scripts properly. The definition, typeClass and the T parameter of this class refer to the type of the value as it should appear in the expression. The actual value may be different when TypedValue is created. The value may get converted as it is passing down the stack. E.g. if we want script variable to contain a user, the type should be declared as UserType, not as object reference - even though the value is object reference when the TypedValue is created. But the reference is resolved down the way to place user in the value.

      • shortDump

        public void shortDump​(StringBuilder sb)
        Description copied from interface: ShortDumpable
        Show the content of the object intended for diagnostics. This method is supposed to append a compact, human-readable output in a single line. Unlike toString() method, there is no requirement to identify the actual class or type of the object. It is assumed that the class/type will be obvious from the context in which the output is used.
        Specified by:
        shortDump in interface ShortDumpable
        Parameters:
        sb - StringBuilder to which to a compact one-line content of the object intended for diagnostics by system administrator should be appended.
