Method Details

updateAtomicValue

public abstract Object updateAtomicValue(Object atomicValue,
 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 Object updateAtomicValue(Object atomicValue,
 Object currentValue,
 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
