137
138 6. Trademarks. This License does not grant permission to use the trade
139 names, trademarks, service marks, or product names of the Licensor,
140 except as required for reasonable and customary use in describing the
141 origin of the Work and reproducing the content of the NOTICE file.

149 PARTICULAR PURPOSE. You are solely responsible for determining the
150 appropriateness of using or redistributing the Work and assume any
151 risks associated with Your exercise of permissions under this License.

161 work stoppage, computer failure or malfunction, or any and all
162 other commercial damages or losses), even if such Contributor
163 has been advised of the possibility of such damages.
164
165 9. Accepting Warranty or Additional Liability. While redistributing
166 the Work or Derivative Works thereof, You may choose to offer,
167 and charge a fee for, acceptance of support, warranty, indemnity,
168 or other liability obligations and/or rights consistent with this
169 License. However, in accepting such obligations, You may act only
170 on Your own behalf and on Your sole responsibility, not on behalf
171 of any other Contributor, and only if You agree to indemnify,
172 defend, and hold each Contributor harmless for any liability
173 incurred by, or claims asserted against, such Contributor by reason
174 of your accepting any such warranty or additional liability.
175
176 END OF TERMS AND CONDITIONS
177

10reflect api that avoids runtime reflect.Value cost
11
12* reflect get/set interface{}, with type checking
13* reflect get/set unsafe.Pointer, without type checking
14* `reflect2.TypeByName` works like `Class.forName` found in java
15
16[json-iterator](https://github.com/json-iterator/go) use this package to save runtime dispatching cost.
17This package is designed for low level libraries to optimize reflection performance.
18General application should still use reflect standard library.
19
20# reflect2.TypeByName
21
22```go
23// given package is github.com/your/awesome-package
24type MyStruct struct {
25 // ...
26}
27
28// will return the type
29reflect2.TypeByName("awesome-package.MyStruct")
30// however, if the type has not been used
31// it will be eliminated by compiler, so we can not get it in runtime
32```
33
34# reflect2 get/set interface{}
35
36```go
37valType := reflect2.TypeOf(1)
38i := 1
39j := 10
40valType.Set(&i, &j)
41// i will be 10
42```
43
44to get set `type`, always use its pointer `*type`
45
46# reflect2 get/set unsafe.Pointer
47
48```go
49valType := reflect2.TypeOf(1)
50i := 1
51j := 10
52valType.UnsafeSet(unsafe.Pointer(&i), unsafe.Pointer(&j))
53// i will be 10
54```
55
56to get set `type`, always use its pointer `*type`
57
58# benchmark
59
60Benchmark is not necessary for this package. It does nothing actually.
61As it is just a thin wrapper to make go runtime public.
62Both `reflect2` and `reflect` call same function
63provided by `runtime` package exposed by go language.
64
65# unsafe safety
66
67Instead of casting `[]byte` to `sliceHeader` in your application using unsafe.
68We can use reflect2 instead. This way, if `sliceHeader` changes in the future,
69only reflect2 need to be upgraded.
70
71reflect2 tries its best to keep the implementation same as reflect (by testing). \ No newline at end of file
