ElementFactory Operations

elementFactoryFind Source

Arguments

:: String	`name` - the name of the desired factory
-> IO (Maybe ElementFactory)	the factory if found, otherwise `Nothing`

Search for an element factory with the given name.

elementFactoryGetElementType Source

Arguments

:: ElementFactoryClass elementFactory
=> elementFactory	`factory` - an element factory
-> IO (Maybe GType)	the type of elements managed by the factory, or `Nothing` if the factory is not loaded

Get the GType for elements managed by the given factory. The type can only be retrieved if the element factory is loaded, which can be assured with pluginFeatureLoad.

elementFactoryGetLongname Source

Arguments

:: ElementFactoryClass elementFactory
=> elementFactory	`factory` - an element factory
-> IO String	the factory's long name

Get the long name for the given factory.

elementFactoryGetKlass Source

Arguments

:: ElementFactoryClass elementFactory
=> elementFactory	`factory` - an element factory
-> IO String	the factory's class

Get the class for the given factory.

elementFactoryGetDescription Source

Arguments

:: ElementFactoryClass elementFactory
=> elementFactory	`factory` - an element factory
-> IO String	the factory's description

Get the description for the given factory.

elementFactoryGetURIType Source

Arguments

:: ElementFactoryClass elementFactory
=> elementFactory	`factory` - an element factory
-> IO Int	the type of URIs supported by the factory

Get the type of URIs supported by the given factory.

elementFactoryGetURIProtocols Source

Arguments

:: ElementFactoryClass elementFactory
=> elementFactory	`factory` - an element factory
-> IO [String]	the supported protocols

Get the list of protocols supported by the given factory.

elementFactoryHasInterface Source

Arguments

:: ElementFactoryClass elementFactory
=> elementFactory	`factory` - an element factory
-> String	`name` - the interface name
-> IO Bool	true if the interface is implemented

Check if the given factory implements the interface with the given name.

Since 0.10.14.

elementFactoryCreate Source

Arguments

:: ElementFactoryClass elementFactory
=> elementFactory	`factory` - an element factory
-> String	`name` - the new element's name
-> IO (Maybe Element)	the new element if it could be created, otherwise `Nothing`

Create a new element of the type supplied by the given factory. It will be given the name supplied.

elementFactoryMake Source

Arguments

:: String	`factoryName` - the name of an element factory
-> Maybe String	`name` - the new element's name, or `Nothing` generate a unique name
-> IO (Maybe Element)	the new element if it could be created, otherwise `Nothing`

Create a new element of the type supplied by the named factory.

elementFactoryCanSinkCaps Source

Arguments
