getReturnType

public Type getReturnType(Type firstArgumentType,
                          Mapping mapping)

从接口复制的说明: SQLFunction

The return type of the function. May be either a concrete type which is preset, or variable depending upon the type of the first function argument.

Note, the 'firstArgumentType' parameter should match the one passed into SQLFunction.render(org.hibernate.type.Type, java.util.List, org.hibernate.engine.spi.SessionFactoryImplementor)

指定者:

getReturnType 在接口中 SQLFunction

覆盖:

getReturnType 在类中 StandardSQLFunction

参数:

firstArgumentType - The type of the first argument

mapping - The mapping source.

返回:

The type to be expected as a return.

protected final int determineJdbcTypeCode(Type type,
                                          Mapping mapping)
                                   throws QueryException

抛出:

QueryException
