Protected Attributes

Vector2 _default
 The default float value. Meaningless if _required is true.
float _scale
 Scale value. Useful for converting units at parse time (i.e. from degrees to radians.
 The parsed generator.
- Protected Attributes inherited from Menge::Attribute
std::string _name
 The name of the xml attribute.
bool _required
 Determines if the XML must specify this attribute.
bool _valid
 Reports if the attribute is valid. An attribute is always valid if it is not required. Otherwise, it is only valid if it was able to be initialized from the XML.

Detailed Description

The class which specifies an xml attribute with a 2D float distribution value.

Constructor & Destructor Documentation

Menge::Vec2DDistributionAttribute::Vec2DDistributionAttribute ( bool  required,
const Vector2 defValue,
float  scale = 1.f 


The 2D Vector generator does not accept an optional prefix like the float and int distributions.

requiredWhether or not the attribute is required (true) or not (false).
defValueThe default value for the attribute if none is provided. This will be interpreted as a const distribution.
scaleThe optional scale value for this float distribution.

Member Function Documentation

bool Menge::Vec2DDistributionAttribute::extract ( TiXmlElement *  node)

Extracts the values for this attribute from the xml node.

This is the main parsing work. It must be performed by each attribute sub-class.

nodeThe XML node containing the attributes.
True on sucessful extraction, false otherwise.

Implements Menge::Attribute.

virtual Vec2DGenerator* Menge::Vec2DDistributionAttribute::getVec2DGenerator ( )

Retrieve the parsed 2D float generator.

A pointer to a 2D float generator. The float generator becomes the responsibility of the caller.
AnAttributeDefinitionException if the types are wrong.

Reimplemented from Menge::Attribute.
