    Constructor and Description
    `RenderVariableBinding(Location location, String description, ComponentResources resources, String name)`

  - ### Method Summary

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `Object` | `get()` Reads the current value of the property (or other resource).
    `Class` | `getBindingType()` Always returns Object since we don't (statically) know the type of object.
    `boolean` | `isInvariant()` Returns false, render variables are always variable.
    `void` | `set(Object value)` Updates the current value.
    `String` | `toString()`

    - #### RenderVariableBinding

          public RenderVariableBinding(Location location,
                                       String description,
                                       ComponentResources resources,
                                       String name)

  - ### Method Detail

    - #### set

          public void set(Object value)

      Description copied from interface: `Binding`
      Updates the current value. Most types of bindings are read-only, and this method will throw a runtime exception. It is the caller's responsibility to ensure that the value passed in is of the appropriate type.
      Specified by:
        `set` in interface `Binding`
      Overrides:
        `set` in class `AbstractBinding`

    - #### isInvariant

          public boolean isInvariant()

      Returns false, render variables are always variable.
      Specified by:
        `isInvariant` in interface `Binding`
      Overrides:
        `isInvariant` in class `AbstractBinding`

    - #### toString

          public String toString()

      Overrides:
        `toString` in class `Object`

    - #### get

          public Object get()

      Description copied from interface: `Binding`
      Reads the current value of the property (or other resource). When reading properties of objects that are primitive types, this will return an instance of the wrapper type. In some cases, a binding is read only and this method will throw a runtime exception.

    - #### getBindingType

          public Class getBindingType()

      Always returns Object since we don't (statically) know the type of object.
      Specified by:
        `getBindingType` in interface `Binding`
      Overrides:
        `getBindingType` in class `AbstractBinding`
