PropertyContext :: value - Get value handle

Implementation overview

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

Implementation details

1. Get context value handle
   odaba::Value & PropertyContext  :: 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 & PropertyContext  :: value ( odaba::String &vSimplePath )
   

   The function returns the value handle for the property path passed in vSimplePath . 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.
