Type: public BasePreferenceData
Specifies an interface to use to determine whether the preference should be visible in the settings or not.
| Parameter Name | Description |
|---|---|
| visibility | An interface invoked to determine whether the preference should be visible under a set of conditions. |
Returned Value: "this", for method chaining.
Type: public boolean
Determine whether the preference should be visible.
Returned Value: True if the preference is visible in the settings.
Type: @Nullable public PreferenceData
Obtain the "preference" that this setting is dependent on, assuming that this preference's visibility is based on the value of another setting.
If this preference doesn't have a "visibility" interface, this will return null. It might return null anyway, who knows.
Returned Value: A PreferenceData that this setting is dependent on. Or null.
Type: public BasePreferenceData
Set whether this preference could use "null" as a value. In other words, if a nonexistent preference should be interpreted differently from simply returning the default value.
| Parameter Name | Description |
|---|---|
| isNullable | Whether the preference's value can be null. |
Returned Value: "this", for method chaining.
Type: public BasePreferenceData
Set a value of the preference that is equivalent to "null". For example, an invalid integer value may be treated separately from the actual preference. Ex: the height of an object, or "0" to disable the object entirely.
| Parameter Name | Description |
|---|---|
| nullValue | The value that should be treated as "null". |
Returned Value: "this", for method chaining.
Type: public boolean
Determine whether the preference can contain a null value.
Returned Value: True if the preference can contain a null value.
Type: @Nullable public T
Obtain the value of the preference to be interpreted as "null". If a value has not been set, this just returns null. Fair enough.
Returned Value: The value of the preference to be interpreted as "null" Might just be null.
Type: public Context
Get the current application context.
Returned Value: The current application context.
Type: public Identifier<T>
Get the identifier of the preference. I'm not sure why this is a separate class, it's mostly for search indexing and stuff. I think I was intending to separate it from the PreferenceData classes to index things other than settings as well, but never got around to it.
Returned Value: A redundant Identifier class containing... an identifier.
Type: public void
Notify all observers that the preference has been changed.
| Parameter Name | Description |
|---|---|
| preference | The new value of the preference. |
