问题描述
之间的语义区别是什么?
What is the semantic difference between:
RttiType.TypeKind和RttiType.Name吗?
RttiType.TypeKind and RttiType.Name ?
我问因为原则上不能从名称推断出TypeKind?
I ask because couldn't one in principle infer the TypeKind from the Name?
推荐答案
是一个字符串。 是枚举类型,适合在循环或 case
语句中使用。它们根本不一样,在实际使用中,从字符串中推断根本不是一回事。
RTTIType.Name
is a string. RTTI.TypeKind
is an enumerated type that is suitable for use in a loop or case
statement. They're not the same at all, and "inferring from a string" is not the same thing at all when it comes to actual use. It's much more clear, concise, and efficient to write
case TypeKind of
tkInteger, tkInt64: DoSomething;
tkEnumeration: DoThisInstead;
...
比写
if (Name = 'tkInteger') or (Name = 'tkInt64') then
DoSomething
else if (Name = 'tkEnumeration') then
DoThisInstead
...
