Check the profiles of the loaded classes.

|

|
|
Abbreviated from “Search-Class”; with the help of this command, you can search out all the loaded classes in JVM. Supported options are: `[d]`、`[E]`、`[f]` and `[x:]`.

|
|
|[d]|print the details of the current class including the source file, class declaration, the class loaders and the like.<br/>F.Y.I if a class is loaded by several class loaders, then the class will be printed several times|
|
||
|
|
|[E]|turn on regx matching while the default is wildcards matching|
|
||
|
|
|[f]|print the fields info of the current class, which should be used along with `-d`|
|
||
|
|
|[x:]|the depth to print the static fields, whose default is `0` - directly invoke the `toString()`|
|
||
|
|
|
||
|
|
Tip:
|
||
|
|
1. *class-patten* supports full qualified class name (e.g. com.taobao.test.AAA and com/taobao/test/AAA)
|
||
|
|
2. `sc` turned on the `sub-class` matching in default mode, if you do want to hide the `sub-class` please just turn it off via `options disable-sub-class true`.
