Class ExpressionCoercionSupport

java.lang.Object

org.hibernate.dialect.function.spi.ExpressionCoercionSupport

@SPI({USE,SUPPLY})
public final class ExpressionCoercionSupport
extends Object

Immutable description of the expression-coercion adaptations required by a Dialect's SQL rendering.

Providers supply a stable profile through Dialect.getExpressionCoercionSupport(). Each requirement directs a focused rendering adaptation. It does not report general database cast support and must not be used as a database-wide implicit-coercion policy.

Since:

8.0
