Detailed Description

Context for generating table requirements.

This context is passed to each TableUpdate's GenerateRequirements method and maintains state about what requirements have already been added to avoid duplicates.

iceberg::TableUpdateContext::TableUpdateContext ( const TableMetadata *  base, bool  is_replace  )

inline

Construct a context for requirement generation.

Parameters
