-------------------------------------MiniScript + Feature----------------------------------

引入
import abc.ddd;
import java.util.Collections as CC;
CC.sort(...);

类
class Dog{
 name
 @Property address

 getname(){
  name+"tt";
 }

 abc(){
  println "ccccc";
 }
};

闭包Closure
sit={ name1,name2 -> println name1+name2+" Sit,Sit! Sit! Good dog"}
sit.call();

集合
aCollect = [5,9,2,4,5,6]

Map 映射
myMap = ["name" : "Groovy","date" : new Date()]
println myMap["date"]
println myMap.date

范围

myRange = 29...32
myInclusiveRange = 2..5
arange = 'a'...'e'
for (i in arange){
  println i
}
负索引
aList = ['python','ruby','groovy']
println aList[-1] // prints groovy
println aList[-3] // prints python
用范围分割
fullname = "Andrew James glover"
mname = fullname[7...13]
print "mIDdle name: " + mname // prints James
Ruby 风格的集合
collec = [1,3,5]
collec << 6 //appended 6 to collec

 

带有迭代器的闭包
[2,6,8,3].find { x |
     if (x == 3){
       println x
     }
}

JavaScript正则表达式
 var p=/^adfsdaf$/

字符内 ${变量}
println "My Lamp has a ${myLamp.basecolor} base"

Groovy 中的新语法
def nfile = ["c:/dev","newfile.txt"] as file
def val = ["http","www.vanwardtechnologies.com","/"] as URL
def ival = ["89.90"] as BigDecimal
println ival as float
 

Groovy的switch语句能够处理各种类型的switch值
case值为类名，匹配switch值为类实例
case值为正则表达式，匹配switch值的字符串匹配该正则表达式
case值为集合，匹配switch值包含在集合中，包括ranges

 

---------------------
printMapClosure = { key,value -> println key + "=" + value }
[ "yue" : "wu","lane" : "burks","sudha" : "saseethiaseeleethialeselan" ].each(printMapClosure)
Produces:

yue=wu
lane=burks
sudha=saseethiaseeleethialeselan

fullString = ""
orderParts = ["BUY",200,"Hot Dogs","1"]
orderParts.each {
  fullString += it + " "
}

println fullString

synchronized n.旗语
semaphore acquire release

*** 作符重载
For example,a + b is the same as a.bopPlus(b).

MiniScript参考：Groovy 、 Sleep 、 ObjectScript 、Yoix、JBasic

GOOD Script:  Groovy、ObjectScript、Rhino、Yoix(AT&T)
