所有方法静态方法具体方法
限定符和类型	方法和说明
`static List`	`arrayAppendFun(List v, Integer i)`
`static long`	`dateFun(Date v)`
`static long`	`timeFun(Time v)`
`static long`	`timestampFun(Timestamp v)`
`static Date`	`toDateFun(int v)` Overloaded, in a challenging way, with `toDateFun(Long)`.
`static Date`	`toDateFun(Long v)`
`static double`	`toDouble(BigDecimal var)` For overloaded user-defined functions that have `double` and `BigDecimal` arguments will go wrong.
`static double`	`toDouble(Double var)`
`static double`	`toDouble(Float var)`
`static long`	`toLong(Date date)` Overloaded functions with DATE, TIMESTAMP and TIME arguments.
`static long`	`toLong(Time time)`
`static long`	`toLong(Timestamp timestamp)`
`static Time`	`toTimeFun(Long v)`
`static Timestamp`	`toTimestampFun(Long v)`
