GetMetadata(Module)

This method creates metadata model for a specified module based on reflection and custom attributes. It only creates ExpressMetaData once for any module. If it already exists it is retrieved from a static cache. However, for a performance reasons try to minimize this and rather keep a single instance reference for your code.

Declaration

public static ExpressMetaData GetMetadata(Module module)

Parameters

Type	Name	Description
System.Reflection.Module	module	Assembly module which contains single schema model

Returns

Type	Description
ExpressMetaData	Meta data structure for the schema defined within the module
