@Incubating public interface HasConfigurableValue
Provider

can be specified directly on the object.
This interface provides methods to manage the lifecycle of the value. Using these methods, the value of the object can be finalized, which means that the value will
no longer change. Note that this is not the same as an immutable value. You can think of a finalized value as similar to a final
variable in Java. While the value does not change,
the value itself may still be mutable.
When a task property has a value of this type, it will be implicitly finalized when the task starts execution, to prevent accidental changes to the task parameters as the task runs.
Note: This interface is not intended for implementation by build script or plugin authors.
Modifier and Type | Method | Description |
---|---|---|
void |
disallowChanges() |
Disallows further direct changes to this object.
|
void |
finalizeValue() |
Calculates the final value of this object and disallows further changes to this object.
|
void finalizeValue()
To calculate the final value of this object, any source for the value is queried and the result used as the final value for this object. The source is discarded.
Subsequent attempts to change the value of this object or the source from which the value is derived will fail with an exception.
Note that although the value of this object will no longer change, the value may itself be mutable. Calling this method does not guarantee that the value will become immutable, though some implementations may support this.
void disallowChanges()
This differs from finalizeValue()
in that it does not calculate the final value of this object, and so any source for the value will continue to be used until
the value is finalized.
