(

)

const

retrieves a valid DataDefinition for the elements datatypes and units.

Returns

const dd::DataDefinition&

getElement()

const dd::StructType::Element & ddl::DDElementRef::getElement

(

)

const

Get the Element object.

Returns

const dd::StructType::Element&

operator=() [1/2]

DDElementRef & ddl::DDElementRef::operator= ( const DDElementRef & )

delete

assignment copy operator

Returns

DDElement& reference

operator=() [2/2]

DDElementRef & ddl::DDElementRef::operator=

(

DDElementRef &&

)

assignment move operator

Returns

DDElement& reference

setComment()

DDElementRef & ddl::DDElementRef::setComment

(

const std::string &

comment

)

Set additional element information to the given element_name.

Parameters

comment

The comment

Returns

*this

setDefaultValue()

DDElementRef & ddl::DDElementRef::setDefaultValue

(

const std::string &

default_value

)

Set the default value information to the element.

Parameters

default_value

The default value

Returns

*this

setDescription()

DDElementRef & ddl::DDElementRef::setDescription

(

const std::string &

description

)

Set the description to the element.

Parameters

description

The description

Returns

*this

setMinMax()

DDElementRef & ddl::DDElementRef::setMinMax	(	const std::string &	minimum_value,
		const std::string &	maximum_value )

Set additional element information to the given element_name.

Parameters

minimum_value	The minimum value
maximum_value	The maximum value

Returns

*this

setScaleOffset()

DDElementRef & ddl::DDElementRef::setScaleOffset	(	const std::string &	scale,
		const std::string &	offset )

Set scale and offset information to the element.

Parameters

scale	The scale
offset	The offset

Returns

*this

setUnit() [1/2]

DDElementRef & ddl::DDElementRef::setUnit

(

const dd::BaseUnit &

base_unit

)

Sets additional unit information to the element. Any other unit information will be overwritten.

Parameters

base_unit

The unit to set

Returns

*this

setUnit() [2/2]

DDElementRef & ddl::DDElementRef::setUnit

(

const DDUnit &

unit

)

Sets additional unit information to the element. Any other unit information will be overwritten.

Parameters

unit	The unit to set

Returns

*this

setValidElementCount()

DDElementRef & ddl::DDElementRef::setValidElementCount

(

const std::string &

valid_element_count

)

Sets the 'valid_element_count' attribute to the element.

Parameters

valid_element_count

The valid_element_count name.

Remarks

The name within valid_element_count must be a sibling element within the same structure. You may use the 'valid_element_count' to mark a subset of the array as valid and the other part as invalid. Use this for a virtual dynamic array and take advantage of the performance of the static array support with dynamic content.

Returns

*this

Exceptions

dd::Error

if element invalidates (i.e. valid_element_count is not a valid sibling element name)

setValue()

DDElementRef & ddl::DDElementRef::setValue

(

const std::string &

value

)

Set the constant value information to the element.

Parameters

value

The value

Returns

*this

Exceptions

dd::Error

if element invalidates (i.e. the constant value is not part of the type)
