Method Detail
-
getActiveValues
SortedSet<ValueOrExpression<T>> getActiveValues()
Get an immutable set view of this property's active values.- Returns:
- Returns an immutable set view of this property's active values. An empty set indicates that there are no active values, and any default values are applicable.
-
getDefaultValues
SortedSet<ValueOrExpression<T>> getDefaultValues()
Get an immutable set view of this property's default values.- Returns:
- Returns an immutable set view of this property's default values. An empty set indicates that there are no default values.
-
getEffectiveValues
SortedSet<ValueOrExpression<T>> getEffectiveValues()
Get an immutable set view of this property's effective values.- Returns:
- Returns an immutable set view of this property's effective values.
-
getPendingValues
SortedSet<ValueOrExpression<T>> getPendingValues()
Get an immutable set view of this property's pending values.Immediately after construction, the pending values matches the active values.
- Returns:
- Returns an immutable set view of this property's pending values. An empty set indicates that there are no pending values, and any default values are applicable.
-
getPropertyDefinition
PropertyDefinition<T> getPropertyDefinition()
Get the property definition associated with this property.- Returns:
- Returns the property definition associated with this property.
-
isEmpty
boolean isEmpty()
Determines whether this property contains any pending values.- Returns:
- Returns
true
if this property does not contain any pending values.
-
isModified
boolean isModified()
Determines whether this property has been modified since it was constructed. In other words, whether the set of pending values differs from the set of active values.- Returns:
- Returns
true
if this property has been modified since it was constructed.
-
wasEmpty
boolean wasEmpty()
Determines whether this property contains any active values.- Returns:
- Returns
true
if this property does not contain any active values.
