  - ### Method Detail

    - #### updateAtomicValue

          public abstract java.lang.Object updateAtomicValue(java.lang.Object atomicValue,
                                                             java.lang.Object currentValue)

      Method to update a live data value with an edited atomic value (such as a string or number). This method will be called when the user edits data in a field of this type, allowing the developer to convert from the atomic type to a raw data value for storage.
      Parameters:
        `atomicValue` - (any) New atomic value. This should match the underlying atomic type specified by the `#inheritsFrom` attribute.
        `currentValue` - Existing data value to be updated.
      Returns:
        (any) Updated data value.

    - #### updateAtomicValue

          public java.lang.Object updateAtomicValue(java.lang.Object atomicValue,
                                                    java.lang.Object currentValue,
                                                    java.lang.String reason)

      Method to uodate a live data value with an edited atomic value atomic value (such as a string or number). This method will be called when the user edits data in a field of this type, allowing the developer to convert from the atomic type to a raw data value for storage. Note, you only need to override this method if you have a need for the additional context provided by the "reason" attribute. The default implementation just ignores the reason and calls the two-param version of updateAtomicValue().
      Parameters:
        `atomicValue` - (any) New atomic value. This should match the underlying atomic type specified by the `#inheritsFrom` attribute.
        `value` - Raw data value to convert. Typically this would be a field value for some record.
        `reason` - A string passed by the framework to indicate why it is updating the atomic value. See `SimpleType.SimpleTypeValueExtractor.getAtomicValue(java.lang.Object, java.lang.String)` for details of the reason strings used by the framework
      Returns:
        Updated data value
