Abstract
The invention discloses an object definition validity check method and device. The method includes: calling an object string returning method for a target object, and acquiring a first returned value returned by the object string returning method; forcibly converting the target object into a basic value type; calling another object string returning method for the target object subjected to forcible conversion, and acquiring a second returned value returned by the object string returning method; determining validity of a definition of the target object according to the first and second returned values. Through the application of the method and device, the problem that validity check for enumerated definitions in related technologies is high in technical complexity and low in execution efficiency is solved, implementation is easier, and execution is more efficient.
Description
Technical field
The present invention relates to the communications field, in particular to a kind of definition validity checking method and device of object.
Background technology
.NET be Microsoft's extend markup language Page Service (Microsoft XML Web services) platform.XML Web services allows application program to carry out communication and shared data by the Internet (Internet), and is which kind of operating system, equipment or programming language regardless of what adopt.Microsoft.NET platform provide create XML Web services and these services are integrated required.
Enumeration type (also referred to as enumerating) provides a kind of effective method for defining one group of name integer constant that can be assigned to variable..NET the enumeration type that the enumerated value under permits using has byte (byte), sbyte, short (short), ushort, integer (int), uint, long (long) or ulong.
When enumerating, inherit from a certain type, when the arbitrary value of this type is paid enumeration object, no matter can normally move when .NET compiles or when .NET moves.Within in service logic, expectation arbitrary value should constrain in the scope of our enumeration definition conventionally.
In correlation technique, adopt following two schemes to realize the validity checking of enumeration definition:
Scheme one: use Enum.IsDefined method to check enumerated value definition, the method can reference: Enum.IsDefined method definition in official of Microsoft document (
http:// msdn.microsoft.com/en-us/library/system.enum.isdefined.a spx).
Inventor finds in research process, and scheme one cannot detect enumerating the situation of combination.
Scheme two: by reflection, obtain enumeration definition, by converting the value of examine to binary numeral, reexamine on each bit (bit) position whether in enumerating, have corresponding definition, for example:
1, check bit flag, check in enumeration definition whether apply System.FlagsAttribute characteristic;
If 2 not application, check by the Enum.IsDefined method providing in scheme one;
If 3 have applied System.FlagsAttribute characteristic, by reflection, obtain all current numerical value of enumerating and define.
Inventor finds in research process, and the technical sophistication degree that scheme two realizes is high, and the execution efficiency of program is low.
Mode technical sophistication degree for the validity checking of enumeration definition in correlation technique is high, and the problem that execution efficiency is low, not yet proposes effective solution at present.
Summary of the invention
