RubyModule.getConstant介绍

[英]Retrieve the named constant, invoking 'const_missing' should that be appropriate.
[中]检索命名常量，如果合适，调用“const_missing”。

代码示例

/**
 * Retrieve the named constant, invoking 'const_missing' should that be appropriate.
 *
 * @param name The constant to retrieve
 * @return The value for the constant, or null if not found
 */
public IRubyObject getConstant(String name) {
  return getConstant(name, true);
}
