 Plugin (Context *context)
 
void SetName (const ea::string &name)
 Name must be set right after creating a plugin object.
 
const ea::string & GetName () const
 Returns a name of the plugin. Name is usually a base name of plugin file.
 
unsigned GetVersion () const

Detailed Description

A base class for plugins of all kinds. It only provides a common plugin interface.

Member Function Documentation

◆ WaitForCompleteFile()

virtual bool Urho3D::Plugin::WaitForCompleteFile ( unsigned  timeoutMs) const
inlinevirtual

This function will block until plugin file is complete and ready to be loaded. Returns false if timeout exceeded, but file is still incomplete.

Reimplemented in Urho3D::ModulePlugin.

Member Data Documentation

◆ application_

SharedPtr<PluginApplication> Urho3D::Plugin::application_
protected

Instance to the plugin application. This should be a single owning reference to the plugin. Managed plugins are an exception as managed object holds reference to native object and must be disposed in order to free this object.
