Methods
activate()
activate():
void|Promise<void>
Defined in: packages/core/src/extension/AbstractExtension.ts:58
Callback for activating the extension in the UI. This is the last method invoked during controller (and extensions) initialization, called after all the promises returned from the Extension#load method have been resolved and the controller has configured the meta manager.
The extension may register any React and DOM event listeners in this method. The extension may start receiving event bus event after this method completes.
Returns
void | Promise<void>
Overrides
beginStateTransaction()
beginStateTransaction():
void
Defined in: packages/core/src/extension/AbstractExtension.ts:109
Starts queueing state patches off the controller state. While the transaction
is active every setState call has no effect on the current state.
Note that call to getState after the transaction has begun will
return state as it was before the transaction.
Returns
void
Overrides
Extension.beginStateTransaction
cancelStateTransaction()
cancelStateTransaction():
void
Defined in: packages/core/src/extension/AbstractExtension.ts:127
Cancels ongoing state transaction. Uncommitted state changes are lost.
Returns
void
Overrides
Extension.cancelStateTransaction
clearPartialState()
clearPartialState():
void
Defined in: packages/core/src/extension/AbstractExtension.ts:155
Clears the current partial state of the extension and sets it value to empty object.
Returns
void
Overrides
commitStateTransaction()
commitStateTransaction():
void
Defined in: packages/core/src/extension/AbstractExtension.ts:118
Applies queued state patches to the controller state. All patches are squashed
and applied with one setState call.
Returns
void
Overrides
Extension.commitStateTransaction
deactivate()
deactivate():
void|Promise<void>
Defined in: packages/core/src/extension/AbstractExtension.ts:65
Callback for deactivating the extension in the UI. This is the first method invoked during extension deinitialization. This usually happens when the user navigates to a different URL.
This method is the lifecycle counterpart of the Extension#activate method.
The extension should deregister listeners registered and release all resources obtained in the Extension#activate method.
Returns
void | Promise<void>
Overrides
destroy()
destroy():
void|Promise<void>
Defined in: packages/core/src/extension/AbstractExtension.ts:51
Finalization callback, called when the controller is being discarded by the application. This usually happens when the user navigates to a different URL.
This method is the lifecycle counterpart of the Extension#init method.
The extension should release all resources obtained in the Extension#init method. The extension must release any resources that might not be released automatically when the extensions's instance is destroyed by the garbage collector.
Returns
void | Promise<void>
Overrides
getAllowedStateKeys()
getAllowedStateKeys(): keyof
S[]
Defined in: packages/core/src/extension/AbstractExtension.ts:204
Returns array of allowed state keys for extension.
Returns
keyof S[]

Inherit Doc
getPartialState()
getPartialState():
Partial<SS>
Defined in: packages/core/src/extension/AbstractExtension.ts:148
Returns the current partial state of the extension.
Returns
Partial<SS>
The current partial state of the extension.
Overrides
getRouteParams()
getRouteParams():
R
Defined in: packages/core/src/extension/AbstractExtension.ts:169
Returns the current route parameters.
Returns
R
The current route parameters.
Overrides
getState()
getState():
SS
Defined in: packages/core/src/extension/AbstractExtension.ts:98
Returns the current state of the controller using this extension.
Returns
SS
The current state of the controller.
Overrides
init()
init():
void|Promise<void>
Defined in: packages/core/src/extension/AbstractExtension.ts:44
Callback for initializing the controller extension after the route parameters have been set on this extension.
Returns
void | Promise<void>
Overrides
load()
load():
S|Promise<S>
Defined in: packages/core/src/extension/AbstractExtension.ts:72
Callback the extension uses to request the resources it needs to render its related parts of the view. This method is invoked after the Extension#init method.
The extension should request all resources it needs in this method, and represent each resource request as a promise that will resolve once the resource is ready for use (these can be data fetched over HTTP(S), database connections, etc).
The method must return a plain flat object. The field names of the object identify the resources being fetched and prepared, each value must be either the resource (e.g. view configuration or a value retrieved synchronously) or a Promise that will resolve to the resource.
The IMA will use the object to set the state of the controller.
Any returned promise that gets rejected will redirect the application to the error page. The error page that will be used depends on the status code of the error.
Returns
S | Promise<S>
A map object of promises resolved when all resources the controller requires are ready. The resolved values will be pushed to the controller's state.
Overrides
setPageStateManager()
setPageStateManager(
pageStateManager?):void
Defined in: packages/core/src/extension/AbstractExtension.ts:176
Sets the state manager used to manage the controller's state..
Parameters
pageStateManager?
PageStateManager<SS>
The current state manager to use.
Returns
void
Overrides
setPartialState()
setPartialState(
partialStatePatch):void
Defined in: packages/core/src/extension/AbstractExtension.ts:136
Patches the partial state of the extension. The extension is able during its load and update phase receive state from active controller using this extension and from previously loaded/updated extensions.
Parameters
partialStatePatch
S
Patch of the controller's state to apply.
Returns
void
Overrides
setRouteParams()
setRouteParams(
params):void
Defined in: packages/core/src/extension/AbstractExtension.ts:162
Sets the current route parameters. This method is invoked before the Extension#init method.
Parameters
params
R = ...
The current route parameters.
Returns
void
Overrides
setState()
setState<
K>(statePatch):void
Defined in: packages/core/src/extension/AbstractExtension.ts:89
Patches the state of the controller using this extension by using the provided object by copying the provided patch object fields to the controller's state object.
Note that the state is not patched recursively but by replacing the values of the top-level fields of the state object.
Note that the extension may modify only the fields of the state that it has specified by its Extension#getAllowedStateKeys method.
Type Parameters
• K extends string | number | symbol
Parameters
statePatch
Patch of the controller's state to apply.
null | S | Pick<S, K>
Returns
void
Overrides
switchToPartialState()
switchToPartialState():
void
Defined in: packages/core/src/extension/AbstractExtension.ts:190
Disables using PageStateManager for getting state.
Returns
void
Overrides
Extension.switchToPartialState
switchToStateManager()
switchToStateManager():
void
Defined in: packages/core/src/extension/AbstractExtension.ts:183
Enables using PageStateManager for getting state.
Returns
void
Overrides
Extension.switchToStateManager
update()
update(
prevParams):S|Promise<S>
Defined in: packages/core/src/extension/AbstractExtension.ts:82
Callback for updating the extension after a route update. This method
is invoked if the current route has the onlyUpdate flag set to true and
the current controller and view match those used by the previously active
route, or, the onlyUpdate option of the current route is a callback and
returned true.
The method must return an object with the same semantics as the result of the Extension#load method. The controller's state will then be patched by the returned object.
The other extension lifecycle callbacks (Extension#init, Extension#load, Extension#activate, Extension#deactivate, Extension#deinit) are not call in case this method is used.
Parameters
prevParams
R = ...
Previous route parameters.
Returns
S | Promise<S>
A map object of promises resolved when all resources the controller requires are ready. The resolved values will be pushed to the controller's state.
