TypeContext :: value - Get value handle

Implementation overview

• Get context value handle
  TypeContext :: value (  )
• Provide value for property path
  TypeContext :: value ( vSimplePath )

Implementation details

1. Get context value handle
   odaba::Value & TypeContext  :: value (  )
   

   The function provides the value handle managed by the context. Typically, the function is called for attributes. When calling the function for a collection property, the value refers to the selected instance in the property handle.

2. Provide value for property path
   odaba::Value & TypeContext  :: value ( odaba::String &vSimplePath )
   

   The function returns the value handle for the property path passed invSimplePath. The function returns values within a complex data type instance (e.g. direction.city, where city is an attribute of the embedded Address type of direction) as well as paths that include references (mother.name, where mother is a reference to a persons mother). You must not pass path properties or operation paths to the function, i.e. the path must not refer to operations or selectors or to iteration operators (mother(0).name is not a valid path).

   When the property could not be found, the function throws an exception.

   • vSimplePath - Simple property path

     A simple property path may contain an extent or property name but also a sequence of property names separated by dot. A simple property path must not contain parenthesis or preceding dots.
