TableMappingInterface

Provides a common interface for mapping field columns to SQL tables.

Warning: using methods provided here should be done only when writing code that is explicitly targeting a SQL-based entity storage. Typically this API is used by SQL storage classes, or other SQL-specific code like the Views integration code for the Entity SQL storage. Another example of legal usage of this API is when needing to write a query that \Drupal::entityQuery() does not support. Always retrieve entity identifiers and use them to load entities instead of accessing data stored in the database directly. Any other usage circumvents the entity system and is strongly discouraged, at least when writing contributed code.
