Class Annotation

All Implemented Interfaces:
AccessControlled, Identifiable

public class Annotation extends BasicItem
This class represents an annotation. Annotations are user-defined properties that can be attached to Annotatable items. They can be very useful in the filtering and analysis process.

An annotation must have an AnnotationType, which controls the type of and how many values that can be attached to an annotation.

      Get the values for this annotation in a specific unit. The values are of a Type appropriate for the given annotation type, ie. Integer object for an integer annotation type. All objects in the list are of the same type.

      public int getValuesVersion()
      Get the version number of the item keeping the values. This is useful when you need to know if the annotation values has been modified by another transaction since they were read from the database. Unlike other items the version number of the annotation item doesn't change when the values are modified.
      Returns:
      The version number as an int.
    • setValueIfDifferent

      public boolean setValueIfDifferent(Object value, Unit unit) throws PermissionDeniedException, InvalidDataException, BaseException
      Set the value of the annotation, replacing any previous values if they are different. No change is made if the new value is the same as the existing value.

      If this annotation type uses project-specific annotations this method behaves differently. If a project is active and this annotation is the default annotation, this method will not update the values. Instead it will load the existing project-specific annotation or create a new one and update that instead (but only if the values are different). Thus, this method may return TRUE even if the valuse in this annotation hasn't changed. The project-specific annotation can be retrieved by calling AnnotationSet.getAnnotation(AnnotationType).

      Parameters:
      value - The new value
      unit - The unit of the value, or null to use the default unit of the annotation type
      Throws:
      PermissionDeniedException - If the logged in user doesn't have write permission for the annotation or read permission for the annotation type
      InvalidDataException - If the value isn't a valid value for the annotation type, see AnnotationType.validateAnnotationValue(Object)
      BaseException - If there is another error
      Since:
      3.8
    • setValuesIfDifferent

      public boolean setValuesIfDifferent(List<?> values, Unit unit) throws PermissionDeniedException, InvalidDataException, BaseException
      Set the values of the annotation, replacing any previous values if they are different. No change is made if the new list of values is the same as the existing values.

      If this annotation type uses project-specific annotations this method behaves differently. If a project is active and this annotation is the default annotation, this method will not update the values. Instead it will load the existing project-specific annotation or create a new one and update that instead (but only if the values are different). Thus, this method may return TRUE even if the valuse in this annotation hasn't changed. The project-specific annotation can be retrieved by calling AnnotationSet.getAnnotation(AnnotationType).

      An exception to the above (since BASE 3.11) is if the annotation was loaded with AnnotationSet.getProjectAnnotation(AnnotationType, Project) in which case currently active project is ignored and the values are always changed on this annotation (eg. the same as if this annotation was not using project-specific annotations). Use the isIgnoringActiveProject() to find out if the active project is ignored or not.

      Parameters:
      values - A list containing the new values
      unit - The unit of the value, or null to use the default unit of the annotation type
      Throws:
      PermissionDeniedException - If the logged in user doesn't have write permission for the annotation or read permission for the annotation type
      InvalidDataException - If the number of values are too many according to the AnnotationType.getMultiplicity() setting any of the values isn't a valid value for the annotation type, see AnnotationType.validateAnnotationValue(Object)
      BaseException - If there is another error
      Since:
      3.8
