public class SetFieldValueCommand
extends ExecutableCommandWrapper
implements ExecutableCommand

Updates the value of specific Item field in the Integrity database.

Constraints:

• The FieldValue must be owned by its Item.
• The FieldValue must reference a Field.

Notes:

• In case the value is a reference to Items (e.g. FieldElementValue or FieldElementListValue), only references to Items which already exist in the database (i.e. whose id is not 0) are created.
• In case the value is a reference to Items, you might prefer to use a CreateRelationshipCommand to control exactly which relations are to be created.
• You might want to group the execution of multiple updates using a CompoundCommand.
• To set a FieldIntValue, FieldDoubleValue or a FieldBooleanValue with the value null, you need to use a specific workaround. For that you need to use a FieldStringValue instead of one of them, referencing the Field to set (setField(Field)) with the value null (setValue(null)).

Usage:

 new SetFieldValueCommand(myValue).execute();
