    • setValueIfAttributeDefined

      public static boolean setValueIfAttributeDefined(BeanDefinitionBuilder builder, Element element, String attributeName, String propertyName)
      Populates the specified bean definition property with the value of the attribute whose name is provided if that attribute is defined in the given element.
      Parameters:
      builder - the bean definition builder to be configured
      element - the XML element where the attribute should be defined
      attributeName - the name of the attribute whose value will be used to populate the property
      propertyName - the name of the property to be populated
      Returns:
      true if defined.
    • setValueIfAttributeDefined

      public static boolean setValueIfAttributeDefined(BeanDefinitionBuilder builder, Element element, String attributeName)
      Populates the bean definition property corresponding to the specified attributeName with the value of that attribute if it is defined in the given element.

      The property name will be the camel-case equivalent of the lower case hyphen separated attribute (e.g. the "foo-bar" attribute would match the "fooBar" property).

      Parameters:
      builder - the bean definition builder to be configured
      element - the XML element where the attribute should be defined
      attributeName - the name of the attribute whose value will be set on the property
      Returns:
      true if defined.

    • isAttributeDefined

      public static boolean isAttributeDefined(Element element, String attributeName)
      Checks the attribute to see if it is defined in the given element.
      Parameters:
      element - the XML element where the attribute should be defined
      attributeName - the name of the attribute whose value will be used as a constructor argument
      Returns:
      true if defined.
    • addConstructorArgValueIfAttributeDefined

      public static boolean addConstructorArgValueIfAttributeDefined(BeanDefinitionBuilder builder, Element element, String attributeName)
      Populates the bean definition constructor argument with the value of that attribute if it is defined in the given element.
      Parameters:
      builder - the bean definition builder to be configured
      element - the XML element where the attribute should be defined
      attributeName - the name of the attribute whose value will be used as a constructor argument
      Returns:
      true if defined.
    • addConstructorArgBooleanValueIfAttributeDefined

      public static void addConstructorArgBooleanValueIfAttributeDefined(BeanDefinitionBuilder builder, Element element, String attributeName, boolean defaultValue)
      Populates the bean definition constructor argument with the boolean value of that attribute if it is defined in the given element or else uses the default provided.
      Parameters:
      builder - the bean definition builder to be configured
      element - the XML element where the attribute should be defined
      attributeName - the name of the attribute whose value will be used as a constructor argument
      defaultValue - the default value to use if the attribute is not set
    • addConstructorArgRefIfAttributeDefined

      public static boolean addConstructorArgRefIfAttributeDefined(BeanDefinitionBuilder builder, Element element, String attributeName)
      Populates the bean definition constructor argument with a reference to a bean with id equal to the attribute if it is defined in the given element.
      Parameters:
      builder - the bean definition builder to be configured
      element - the XML element where the attribute should be defined
      attributeName - the name of the attribute whose value will be used to set the reference
      Returns:
      true if defined.
    • addConstructorArgParentRefIfAttributeDefined

      public static boolean addConstructorArgParentRefIfAttributeDefined(BeanDefinitionBuilder builder, Element element, String attributeName)
      Populates the bean definition constructor argument with a reference to a bean with parent id equal to the attribute if it is defined in the given element.
      Parameters:
      builder - the bean definition builder to be configured
      element - the XML element where the attribute should be defined
      attributeName - the name of the attribute whose value will be used to set the reference
      Returns:
      true if defined.
    • setReferenceIfAttributeDefined

      public static boolean setReferenceIfAttributeDefined(BeanDefinitionBuilder builder, Element element, String attributeName, String propertyName)
      Populates the specified bean definition property with the reference to a bean. The bean reference is identified by the value from the attribute whose name is provided if that attribute is defined in the given element.
      Parameters:
      builder - the bean definition builder to be configured
      element - the XML element where the attribute should be defined
      attributeName - the name of the attribute whose value will be used as a bean reference to populate the property
      propertyName - the name of the property to be populated
      Returns:
      true if the attribute is present and has text
    • setReferenceIfAttributeDefined

      public static boolean setReferenceIfAttributeDefined(BeanDefinitionBuilder builder, Element element, String attributeName)
      Populates the bean definition property corresponding to the specified attributeName with the reference to a bean identified by the value of that attribute if the attribute is defined in the given element.

      The property name will be the camel-case equivalent of the lower case hyphen separated attribute (e.g. the "foo-bar" attribute would match the "fooBar" property).

      Parameters:
      builder - the bean definition builder to be configured
      element - the XML element where the attribute should be defined
      attributeName - the name of the attribute whose value will be used as a bean reference to populate the property
