Detailed Description

template<typename type>
struct mudbox::AttributeInstance< type >

This is a generic attribute which can be used instead of the standard built in types.

The difference between a standard type and this attribute is that this attribute can be viewed and its value can be changed by the user. Attributes can be linked together also so when the value of an attribute is changed, all target attributes value will be changed also. The owner node also can catch events regarding to the attrbibutes, for example when the user changes the value.

Member Function Documentation

template<typename type>
const type& mudbox::AttributeInstance< type >::Value (  void   )  const [inline]
 

Returns the value of the attribute.

00375 { return m_cValue; };
template<typename type>
virtual void mudbox::AttributeInstance< type >::SetValue (  type  cValue,
bool  bInternal = false
)  [inline, virtual]
 

Set the value of the attribute to cValue.

Parameters:
bInternal  if this is false the owner node will receive an event about the value change (See NodeEventType::etValueChanged).
