Detailed Description

Singleton accessor that owns a lazily loaded SchemaPluginInterface plugin.

Subsequent get() invocations are cheap and return the cached singleton regardless of the argument passed; the very first call wins. The destructor releases the contained interface before tearing down the Plugin loader, ensuring the shared object outlives any dependent global objects inside it.

Member Function Documentation

get()

static SchemaPluginManager& vlink::SchemaPluginManager::get ( const std::string &  schema_plugin_path = "" )

static

Returns the process-wide manager, building it on the first call.

Parameters

schema_plugin_path

Absolute path to the plugin shared object. Empty means fall back to the VLINK_SCHEMA_PLUGIN environment variable.

Returns

Reference to the singleton instance.

get_interface()

std::shared_ptr<SchemaPluginInterface> vlink::SchemaPluginManager::get_interface

(

)

const

Returns the shared plugin instance, or nullptr when the manager is invalid.

Returns

Shared pointer to the loaded SchemaPluginInterface implementation.

is_valid()

bool vlink::SchemaPluginManager::is_valid

(

)

const

Reports whether a plugin was successfully loaded.

Returns

true when get_interface() will yield a non-null pointer.
