Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.lang.String`	`getFallbackValue()`	Returns the fallback value or an empty string if not defined.
`java.lang.String`	`getName()`	Returns the name of the deferred binding property.
`java.util.SortedSet<java.lang.String>`	`getPossibleValues()`	Returns all possible values for this deferred binding property.
`java.lang.String`	`getPropertyProvider(TreeLogger logger, java.util.SortedSet<ConfigurationProperty> configProperties)`	Returns a raw function body that provides the runtime value to be used for a deferred binding property.
`boolean`	`isDerived()`	Returns `true` if the value of the SelectionProperty is always derived from other SelectionProperties and, as a consequence, the property provider never needs to be evaluated.
`java.lang.String`	`tryGetValue()`	Returns the defined value for the deferred binding property or `null` if the value of the property is not constant.

                              throws UnableToCompleteException
```
    Returns a raw function body that provides the runtime value to be used for a deferred binding property.
    
    Parameters:
    
    logger - logger to use for any warnings/errors
    
    configProperties - set of configuration properties
    
    Throws:
    
    UnableToCompleteException - if execution cannot continue, after having logged a message
