Class AbstractOracleTypeConvertersFactory

java.lang.Object

io.micronaut.data.model.runtime.convert.vector.impl.AbstractOracleTypeConvertersFactory

@Internal
public abstract class AbstractOracleTypeConvertersFactory
extends Object

Shared helpers for Oracle VECTOR converters. This class intentionally avoids any dependency on Oracle driver or Micronaut runtime types. Methods are protected static so vendor-specific factories can reuse them. This type is intentionally non-sealed because concrete Oracle converter factories live in JDBC and R2DBC modules.

Since:

5.0.0
