Types

type LoaderInterface added in v0.5.4

type LoaderInterface interface {
	// Adds a hook to the loader, which will be invoked at a specific time according
	// to the hook type. See the specific hooks for more information.
	Hook(h any)
}

type PluginLoader

type PluginLoader struct {
	// contains filtered or unexported fields
}

func NewPluginLoader

func NewPluginLoader() *PluginLoader

func (*PluginLoader) Complete added in v0.5.4

func (p *PluginLoader) Complete()

Complete marks the plugin loader as completed. This function will be called automatically by LoadPlugins(), although it can be called manually if LoadPlugins() is not used. It is not safe to call this function and LoadPlugins() on the same plugin loader. It will invoke LoadingCompletedHooks in parallel and does not block.

func (*PluginLoader) Hook added in v0.5.4

func (p *PluginLoader) Hook(h any)

func (*PluginLoader) LoadOne added in v0.5.4

func (p *PluginLoader) LoadOne(ctx context.Context, md meta.PluginMeta, cc *plugin.ClientConfig)

LoadOne loads a single plugin. It invokes PluginLoadHooks for the type of the plugin being loaded and will block until all load hooks have completed.

func (*PluginLoader) LoadPlugins added in v0.5.4

func (p *PluginLoader) LoadPlugins(ctx context.Context, conf v1beta1.PluginsSpec, scheme meta.Scheme, reattach ...*plugin.ReattachConfig)

LoadPlugins loads a set of plugins defined by the plugin configuration. This function loads plugins in parallel and does not block. It will invoke LoadingCompletedHooks once all plugins have been loaded. Once this function is called, it is unsafe to call LoadPlugins() or LoadOne() again for this plugin loader, although new hooks can still be added and will be invoked immediately according to the current state of the plugin loader.
