Processing Context

→ a collection of different data structures that provide every contextual information needed for extracting language concepts from the scanned source code

Consists of:

• information about the current position within the AST (i.e. reference to the current AST node object)
• global context with information about the currently processed project and file along with other references to native APIs
• local contexts containing data structures shared between different processors
• a list of active metadata assignment rules

Implementation

• Node refers to the type provided by the used AST parser API
