Detailed Description

A a data set object.

Data objects consist of property-value pairs.

Constructor & Destructor Documentation

DataObject()

DataObject::DataObject

(

DataSet *

parent_set

)

Create a data object.

Parameters

parent_set

Data set that the object will belong to.

Member Function Documentation

eraseProperty()

void DataObject::eraseProperty

(

DataProperty *

property

)

Unset (erase value) a property.

Parameters

property

Property to unset.

getNonlocalizedKeyProperty()

const std::string & DataObject::getNonlocalizedKeyProperty

(

DataProperty *

property

)

Returns unparsed untranslated value for a key property. Used when a text value is translated, but the original value still is needed as a reference key.

Parameters

property

Property to read.

Returns

Unparsed untranslated value or empty string if property value is not set.

getProperty()

const std::string & DataObject::getProperty	(	DataProperty *	property,
		int *	is_approximate = NULL )

Returns unparsed value for a property.

Parameters

	property	Property to read.
[out]	is_approximate	If the value is approximate. Is set to 1 for approximate, 0 for exact, -1 for property default, if not NULL.

Returns

Unparsed value or empty string if property value is not set.

getPropertyDisplayString()

std::string DataObject::getPropertyDisplayString

(

DataProperty *

property

)

Returns value for a property in a format suitable for display with unit appended.

Parameters

property

Property to read.

Returns

Value in display format or empty string if property value is not set.

getPropertyInputString()

std::string DataObject::getPropertyInputString

(

DataProperty *

property

)

Returns value for a property in a format suitable for use in expressions with unit appended.

Parameters

property

Property to read.

Returns

Value in input format or empty string if property value is not set.

getPropertyStruct()

const MathStructure * DataObject::getPropertyStruct

(

DataProperty *

property

)

Returns parsed value for a property. Parses the text string value if not parsed before

Parameters

property

Property to read.

Returns

Parsed value or NULL if property value is not set.

isUserModified()

bool DataObject::isUserModified

(

)

const

If the object has been modified by the end user (if setUserModified() has been called).

Returns

true if the object has been modified by the user.

parentSet()

DataSet * DataObject::parentSet

(

)

const

Returns the data set that the object belongs to.

Returns

Parent data set.

setNonlocalizedKeyProperty()

void DataObject::setNonlocalizedKeyProperty	(	DataProperty *	property,
		std::string	s_value )

Set an untranslated value for a key property. Used when a text value is translated, but the original value still is needed as a reference key.

Parameters

property	Property to set (must belong to parent data set).
s_value	Value for the property.

setProperty()

void DataObject::setProperty	(	DataProperty *	property,
		std::string	s_value,
		int	is_approximate = -1 )

Set value for a property.

Parameters

property	Property to set (must belong to parent data set).
s_value	Value for the property.
is_approximate	If the value is approximate. 1 for approximate, 0 for exact, -1 for property default.

setUserModified()

void DataObject::setUserModified

(

bool

user_modified = true

)

Specify if the object has been modified by the end user.

Parameters

user_modified

true if the object has been modified by the user.
