类 ConditionalParenthesisFunction

java.lang.Object

org.hibernate.dialect.function.StandardSQLFunction

org.hibernate.dialect.function.ConditionalParenthesisFunction

所有已实现的接口:

SQLFunction

public class ConditionalParenthesisFunction
extends StandardSQLFunction

Essentially the same as StandardSQLFunction, except that here the parentheses are not included when no arguments are given.

ConditionalParenthesisFunction

public ConditionalParenthesisFunction(String name)

Constructs a ConditionalParenthesisFunction with the given name

参数:

name - The function name

ConditionalParenthesisFunction

public ConditionalParenthesisFunction(String name,

type - The function return type

方法详细资料

hasParenthesesIfNoArguments

public boolean hasParenthesesIfNoArguments()

从接口复制的说明: SQLFunction

If there are no arguments, are parentheses required?

指定者:

hasParenthesesIfNoArguments 在接口中 SQLFunction

覆盖:

hasParenthesesIfNoArguments 在类中 StandardSQLFunction

返回:

True if a no-arg call of this function requires parentheses.

render

public String render(Type firstArgumentType,
                     List arguments,
                     SessionFactoryImplementor sessionFactory)

从接口复制的说明: SQLFunction

Render the function call as SQL fragment.

Note, the 'firstArgumentType' parameter should match the one passed into SQLFunction.getReturnType(org.hibernate.type.Type, org.hibernate.engine.spi.Mapping)

指定者:

render 在接口中 SQLFunction

覆盖:

render 在类中 StandardSQLFunction

参数:

firstArgumentType - The type of the first argument

arguments - The function arguments

sessionFactory - The SessionFactory

返回:

The rendered function call
