GI.GObject.Structs.ParamSpecPool

Contents

Description

A ParamSpecPool maintains a collection of GParamSpecs which can be quickly accessed by owner and name.

The implementation of the Object property system uses such a pool to store the GParamSpecs of the properties all object types.

Synopsis

Arguments

:: (HasCallStack, MonadIO m)
=> ParamSpecPool	`pool`: a `ParamSpecPool`.
-> GParamSpec	`pspec`: the `ParamSpec` to insert
-> GType	`ownerType`: a `GType` identifying the owner of `pspec`
-> m ()

Inserts a ParamSpec in the pool.

Arguments

:: (HasCallStack, MonadIO m)
=> ParamSpecPool	`pool`: a `ParamSpecPool`
-> GType	`ownerType`: the owner to look for
-> m [GParamSpec]	Returns: a `List` of all `GParamSpecs` owned by `ownerType` in the pool`GParamSpecs`.

Gets an List of all GParamSpecs owned by ownerType in the pool.

Arguments

:: (HasCallStack, MonadIO m)
=> ParamSpecPool	`pool`: a `ParamSpecPool`
-> Text	`paramName`: the name to look for
-> GType	`ownerType`: the owner to look for
-> Bool	`walkAncestors`: If `True`, also try to find a `ParamSpec` with `paramName` owned by an ancestor of `ownerType`.
-> m (Maybe GParamSpec)	Returns: The found `ParamSpec`, or `Nothing` if no matching `ParamSpec` was found.

Looks up a ParamSpec in the pool.

Arguments

:: (HasCallStack, MonadIO m)
=> ParamSpecPool	`pool`: a `ParamSpecPool`
