        `value` -

    - #### setAttribute

          public void setAttribute(java.lang.String property,

      Parameters:
        `property` -
        `value` -

    - #### setAttribute

          public void setAttribute(java.lang.String property,
                          ValueEnum value)

      Set attribute value as a ValueEnum. The value of the ValueEnum will be stored on the underlying data object.
      Parameters:
        `property` -
        `value` -

    - #### setAttribute

          public void setAttribute(java.lang.String property,
                          java.lang.Object value)

      Set the attribute value to an Object.

      The values provided as attributes are generally expected to contain valid values for a field of a DataBoundComponent. Therefore this method converts the value passed in to an equivalent object in JavaScript before storing on underlying data object.
      Developers can use `setAttributeAsJavaObject(String, Object)` to store Java objects without converting to JavaScript.

      Conversions that occur include:

      - Numeric data types will be represented as JavaScript Number
      - Dates (and subclasses) will be stored as JavaScript Date
      - Java Arrays will be stored as JavaScript Array, with members converted to the equivalent JavaScript type where appropriate
      - Java Collections (including List, Set) will be stored as JavaScript Array, with members converted to the equivalent JavaScript object (recursively) where appropriate
      - Maps are stored as JavaScript Objects with each key mapped to a property on the object. Property values are converted to the equivalent JavaScript object (recursively) where appropriate
      Other Java Objects, including POJOs are stored on the underlying data object unconverted. Developers can retrieve such values via `getAttributeAsObject(String)`.
      Parameters:
        `property` - the attribute name
        `value` - the attribute value.

    - #### setAttributeAsJavaObject

          public void setAttributeAsJavaObject(java.lang.String property,
                                      java.lang.Object value)

      Set the attribute value to an Object.

      Unlike `setAttribute(String, Object)`, this method will store the value passed in as-is rather than converting to an equivalent object in JavaScript.

        `property` -
        `value` -

    - #### setAttribute
