getExtensionByName

iOExtensionPointGetExtensionByName

Arguments

:: (HasCallStack, MonadIO m)

=> IOExtensionPoint

extensionPoint: a IOExtensionPoint

-> Text

name: the name of the extension to get

-> m IOExtension

Returns: the IOExtension for extensionPoint that has the given name, or Nothing if there is no extension with that name

Finds a IOExtension for an extension point by name.

getExtensions

iOExtensionPointGetExtensions

Arguments

:: (HasCallStack, MonadIO m)

=> IOExtensionPoint

extensionPoint: a IOExtensionPoint

-> m [IOExtension]

Returns: a List of GIOExtensions. The list is owned by GIO and should not be modified.

Gets a list of all extensions that implement this extension point. The list is sorted by priority, beginning with the highest priority.

getRequiredType

iOExtensionPointGetRequiredType

Arguments

:: (HasCallStack, MonadIO m)

=> IOExtensionPoint

extensionPoint: a IOExtensionPoint

-> m GType

Returns: the GType that all implementations must have, or G_TYPE_INVALID if the extension point has no required type

Gets the required type for extensionPoint.

implement

iOExtensionPointImplement

Arguments

:: (HasCallStack, MonadIO m)

=> Text

extensionPointName: the name of the extension point

-> GType

type: the GType to register as extension

-> Text

extensionName: the name for the extension

-> Int32

priority: the priority for the extension

-> m IOExtension

Returns: a IOExtension object for GType

Registers type as extension for the extension point with name extensionPointName.

If type has already been registered as an extension for this extension point, the existing IOExtension object is returned.

lookup

iOExtensionPointLookup

Arguments

:: (HasCallStack, MonadIO m)

=> Text

name: the name of the extension point

-> m IOExtensionPoint

Returns: the IOExtensionPoint, or Nothing if there is no registered extension point with the given name.

Looks up an existing extension point.

register

iOExtensionPointRegister

Arguments

:: (HasCallStack, MonadIO m)

=> Text

name: The name of the extension point

-> m IOExtensionPoint

Returns: the new IOExtensionPoint. This object is owned by GIO and should not be freed.

Registers an extension point.

setRequiredType

iOExtensionPointSetRequiredType

Arguments

:: (HasCallStack, MonadIO m)

=> IOExtensionPoint

extensionPoint: a IOExtensionPoint

-> GType

type: the GType to require

-> m ()

Sets the required type for extensionPoint to type. All implementations must henceforth have this type.
