AfterInit(PluginLoader.PluginInfo, IPlugin)

Called after a plugin has been fully initialized, whether or not there is an Init method. This should never throw an exception.

Declaration

public virtual void AfterInit(PluginLoader.PluginInfo plugin, IPlugin pluginInstance)

Parameters

Type	Name	Description
PluginLoader.PluginInfo	plugin	the plugin that was just initialized
IPlugin	pluginInstance	the instance of the plugin being initialized

BeforeInit(PluginLoader.PluginInfo)

Called before a plugin's Init method is called. This will not be called if there is no Init method. This should never throw an exception. An exception will abort the loading of the plugin with an error.

Declaration

public virtual bool BeforeInit(PluginLoader.PluginInfo plugin)

Parameters

Type	Name	Description
PluginLoader.PluginInfo	plugin	the plugin to be initialized

Returns

Type	Description
Boolean	whether or not to call the Init method

BeforeLoad(PluginLoader.PluginMetadata)

Called before a plugin is loaded. This should never throw an exception. An exception will abort the loading of the plugin with an error.

Declaration

public virtual bool BeforeLoad(PluginLoader.PluginMetadata plugin)

Parameters

Type	Name	Description
PluginLoader.PluginMetadata	plugin	the plugin about to be loaded

Returns

Type	Description
Boolean	whether or not the plugin should be loaded

Remarks

The assembly will still be loaded, but the plugin will not be constructed if this returns false. Any features it defines, for example, will still be loaded.

Evaluate()

Evaluates the Feature for use in conditional meta-Features. This should be re-calculated on every call, unless it can be proven to not change.

This will be called on every feature that returns true from Initialize(PluginLoader.PluginMetadata, String[])

Declaration

public virtual bool Evaluate()

Returns

Type	Description
Boolean	the truthiness of the Feature.

Initialize(PluginLoader.PluginMetadata, String[])

Initializes the feature with the parameters provided in the definition.

Note: When no parenthesis are provided, parameters is an empty array.

Declaration

public abstract bool Initialize(PluginLoader.PluginMetadata meta, string[] parameters)

Parameters

Type	Name	Description
PluginLoader.PluginMetadata	meta	the metadata of the plugin that is being prepared
String[]	parameters	the parameters passed to the feature definition, or null

Returns

Type	Description
Boolean	true if the feature is valid for the plugin, false otherwise

Remarks

This gets called BEFORE your Init method.

Returning false does not prevent the plugin from being loaded. It simply prevents the feature from being used.

Declaration

protected void RequireLoaded(PluginLoader.PluginMetadata plugin)

Parameters
