Interface SelectionProperty

public interface SelectionProperty

Represents a deferred binding property. The deferred binding property may or may not have a single value applied across all permutations. SelectionProperty implementations must support object identity comparisons.

• A similarly-named interface used in generators.

Method Summary

Modifier and Type	Method	Description
String	getFallbackValue()	Returns the fallback value or an empty string if not defined.
String	getName()	Returns the name of the deferred binding property.
SortedSet<String>	getPossibleValues()	Returns all possible values for this deferred binding property.
String	getPropertyProvider(TreeLogger logger, 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.
String	tryGetValue()	Returns the defined value for the deferred binding property or null if the value of the property is not constant.
