EOColumnTypes

Declared in: EOAccess/EOSchemaSynchronization.h

Protocol Description

This protocol describes the API for interacting with objects passed as arguments to the following EOSQLExpression methods:

• + isColumnType:equivalentToColumnType:options:
• + phraseCastingColumnNamed:fromType:toType:options:
• + statementsToConvertColumnNamed:inTableNamed:fromType:toType:options:

You only need to know about this protocol if you are implementing schema synchronization API for a custom adaptor. In that case, you don't have to implement a class that adopts this protocol; EOSQLExpression's implementation of the schema synchronization API uses a private class that implements it. You only need to know about the protocol because your method implementations of the above methods needs to compare two objects that adopt the protocol.
