Method Details

attribute

Attribute<T> attribute()

Returns:

the attribute

original

@Nullable T original()

Returns:

the original value, or the current one if not modified

See Also:

• modified()

revert

void revert()

Reverts to the original value if modified

validate

void validate()

Updates the valid state of this value according to the underlying validator

See Also:

• valid()

persist

State persist()

Returns a State controlling whether the last used value for this attribute should persist when defaults are set.

Returns:

a State controlling whether the given attribute value should persist when defaults are set

See Also:

• EntityEditor.defaults()
• EntityEditor.PERSIST_FOREIGN_KEYS

valid

ObservableState valid()

Returns:

an ObservableState indicating the valid status of this attribute value.

present

ObservableState present()

Returns:

an ObservableState indicating whether the value of this attribute is non-null

message

Observable<String> message()

Returns:

the validation message in case the value is invalid, otherwise the attribute description

modified

ObservableState modified()

Returns an ObservableState instance indicating whether the value of the given attribute has been modified.

Note that only attributes of existing entities are modified, attributes of new, or non-existing entities are never modified.

Returns:

an ObservableState indicating the modified state of the value of the given attribute

See Also:

• EntityEditor.modified()

edited

Observer<T> edited()

Returns an observer notified each time this value is modified via Value.set(Object).

This event is NOT triggered when the value changes due to the entity being set via EntityEditor.set(Entity), EntityEditor.defaults() or EntityEditor.clear().

Note that this event is only triggered if the value actually changes.

Returns:

an observer notified when the given attribute value is edited

defaultValue

Value<Supplier<T>> defaultValue()

Returns the Value instance controlling the default value supplier for the given attribute.

Used when the underlying value is not persistent.

Use EntityEditor.defaults() to populate the editor with default values.

Returns:

the Value instance controlling the default value supplier

• persist()
