Ruby Hash inspect()用法及代码示例

Hash＃inspect()是一种Hash类方法，它给出哈希的字符串表示形式。

用法：Hash.inspect()

参数：散列值

返回：哈希的字符串表示形式

范例1：

# Ruby code for Hash.inspect() method 
  
# declaring Hash value 
a = {a:100, b:200} 
  
# declaring Hash value 
b = {a:100, c:300, b:200} 
  
# declaring Hash value 
c = {a:100} 
  
  
# inspect Value 
puts "Hash a inspect form : #{a.inspect()}\n\n"
  
puts "Hash b inspect form : #{b.inspect()}\n\n"
  
puts "Hash c inspect form : #{c.inspect()}\n\n"

输出：

Hash a inspect form : {:a=>100, :b=>200}

Hash b inspect form : {:a=>100, :c=>300, :b=>200}

Hash c inspect form : {:a=>100}

示例2:

# Ruby code for Hash.inspect() method 
  
# declaring Hash value 
a = { "a" => 100, "b" => 200 } 
  
# declaring Hash value 
b = {"a" => 100} 
  
# declaring Hash value 
c = {"a" => 100, "c" => 300, "b" => 200} 
  
  
# inspect Value 
puts "Hash a inspect form : #{a.inspect()}\n\n"
  
puts "Hash b inspect form : #{b.inspect()}\n\n"
  
puts "Hash c inspect form : #{c.inspect()}\n\n"

输出：

Hash a inspect form : {"a"=>100, "b"=>200}

Hash b inspect form : {"a"=>100}

Hash c inspect form : {"a"=>100, "c"=>300, "b"=>200}
