std.reflect

Function Description

The reflect package provides reflection functionality, allowing the program to obtain the type information of various instances at runtime and perform various read, write, and call operations.

This package currently does not work on macOS.

NOTE

For global information, the reflection functionality of Cangjie only supports accessing public global variables and global functions.

For the current package, the reflection functionality of Cangjie supports accessing all globally defined types. For externally imported packages or dynamically loaded modules, only the globally defined public types can be accessed.

For member information, the reflection functionality of Cangjie only supports accessing public members (instances/static variables/properties/functions) in the type. Members with non-public modifiers or default modifiers are invisible.

Currently, the reflection functionality of Cangjie does not support the function type, tuple type, and enum type.
