  • Method Details

    • isEntity

      public static boolean isEntity(Object entity)

    • getId

      @Nullable public static Object getId(Object entity)

    • setId

      public static void setId(Object entity, Object key)

    • getIdOrEntity

      public static Object getIdOrEntity(Object entity)

    • getGeneratedId

      public static Object getGeneratedId(Object entity)

    • setGeneratedId

      public static void setGeneratedId(Object entity, Object id)

    • setValue

      public static void setValue(Object entity, String name, Object value)
      Set an attribute value.
      An implementor should first read a current value of the attribute, and then call an appropriate setter method only if the new value differs. This ensures triggering of EntityPropertyChangeListeners only if the attribute was actually changed.
      Parameters:
      name - attribute name according to JavaBeans notation
      value - attribute value

    • setValue

      public static void setValue(Object entity, String name, Object value, boolean checkEquals)
      Set an attribute value.
      An implementor should first read a current value of the attribute, and then call an appropriate setter method only if the new value differs. This ensures triggering of EntityPropertyChangeListeners only if the attribute was actually changed.
      Parameters:
      name - attribute name according to JavaBeans notation
      value - attribute value
      checkEquals - check equals for previous and new value. If flag is true and objects equals, then setter will not be invoked

    • getValue

      @Nullable public static <T> T getValue(Object entity, String name)
      Get an attribute value.
      Parameters:
      name - attribute name according to JavaBeans notation
      Returns:
      attribute value

    • getValueEx

      @Nullable public static <T> T getValueEx(Object entity, String propertyPath)
      Get an attribute value. Locates the attribute by the given path in object graph starting from this instance.
      The path must consist of attribute names according to JavaBeans notation, separated by dots, e.g. car.driver.name.
      Parameters:
      propertyPath - path to an attribute
      Returns:
      attribute value. If any traversing attribute value is null or is not an Entity, this method stops here and returns this value.

    • getValueEx

      @Nullable public static <T> T getValueEx(Object entity, PropertyPath propertyPath)
      Get an attribute value. Locates the attribute by the given path in object graph starting from this instance.
      The path must consist of attribute names according to JavaBeans notation, separated by dots, e.g. car.driver.name.
      Parameters:
      propertyPath - path to an attribute
      Returns:
      attribute value. If any traversing attribute value is null or is not an Entity, this method stops here and returns this value.

    • setValueEx

      public static void setValueEx(Object entity, String propertyPath, Object value)
      Set an attribute value. Locates the attribute by the given path in object graph starting from this instance.
      The path must consist of attribute names according to JavaBeans notation, separated by dots, e.g. car.driver.name.
      In the example above this method first gets value of car.driver attribute, and if it is not null and is an Entity, sets value of name attribute in it.
      An implementor should first read a current value of the attribute, and then call an appropriate setter method only if the new value differs. This ensures triggering of EntityPropertyChangeListeners only if the attribute was actually changed.
      Parameters:
      propertyPath - path to an attribute
      value - attribute value

    • setValueEx

      public static void setValueEx(Object entity, PropertyPath propertyPath, Object value)
      Set an attribute value. Locates the attribute by the given path in object graph starting from this instance.
      The path must consist of attribute names according to JavaBeans notation, separated by dots, e.g. car.driver.name.
      In the example above this method first gets value of car.driver attribute, and if it is not null and is an Entity, sets value of name attribute in it.
      An implementor should first read a current value of the attribute, and then call an appropriate setter method only if the new value differs. This ensures triggering of EntityPropertyChangeListeners only if the attribute was actually changed.
      Parameters:
      propertyPath - path to an attribute
      value - attribute value

    • setValueEx

      public static void setValueEx(Object entity, String[] properties, Object value)
      Set value of an attribute according to the rules described in setValueEx(Object, String, Object).
      Parameters:
      entity - instance
      properties - path to the attribute
      value - attribute value

    • getValueEx

      public static <T> T getValueEx(Object entity, String[] properties)
      Get value of an attribute according to the rules described in getValueEx(Object, String).
      Parameters:
      entity - entity
      properties - path to the attribute
      Returns:
      attribute value

    • propertyValueEquals

      public static boolean propertyValueEquals(@Nullable Object a, @Nullable Object b)
      Checks whether an entity property value has been changed.
      Parameters:
      a - an object
      b - an object
      Returns:
      true if a equals to b, but in case of a is an entity or a collection returns true only if a is the same instance as b
