be fully defined as an abstract model made of several objects, each of which represents a function or a specific IED attribute, similar to the object modeling paradigm. It provides a hierarchical information or
Composite types define collections. These collections could be an ordered grouping of the same type of scalar object – arrays, or of different types of scalar objects and/or other composite types – records. Let's start with arrays: As was just mentioned, arrays are used for gathering multipl...
ColdFusion built-in complex data types include arrays, structures, queries, and XML document objects. You cannot use a complex variable, such as an array, directly in a ColdFusion expression, but you can use simple data type elements of a complex variable in an expression. For example, with...

当你看到“Cannot interpret ‘<attribute ‘dtype‘ of ‘numpy.generic‘ objects>‘ as a data type”这个错误时,通常是因为你试图将一个不支持的数据类型转换为数值类型。可能的原因和解决方案包括: 数据类型不匹配:确保你正在尝试转换的数据是正确的数据类型。例如,如果你试图将字符串转换为整数,你需要先将...
type, ActionScript 3.0 defines several more commonly used data types, such as String, Number, and Array. You can define your own data types by using classes or interfaces to define a custom set of values. All values in ActionScript 3.0, whether they are primitive or complex,are objects. ...
