public class DeviceProviderFactory
extends PluginFeature

GstDeviceProviderFactory is used to create instances of device providers. A GstDeviceProviderfactory can be added to a GstPlugin as it is also a GstPluginFeature.

Use the gst_device_provider_factory_find() and gst_device_provider_factory_get() functions to create device provider instances or use gst_device_provider_factory_get_by_name() as a convenient shortcut.

Constructor Details

DeviceProviderFactory

public DeviceProviderFactory(MemorySegment address)

Create a DeviceProviderFactory proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static Type getType()

Get the GType of the DeviceProviderFactory class

Returns:

the GType

asParent

protected DeviceProviderFactory asParent()

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class PluginFeature

find

public static DeviceProviderFactory find(String name)

Search for an device provider factory of the given name. Refs the returned device provider factory; caller is responsible for unreffing.

Parameters:

name - name of factory to find

Returns:

GstDeviceProviderFactory if found, null otherwise

getByName

public static DeviceProvider getByName(String factoryname)

Returns the device provider of the type defined by the given device provider factory.

Parameters:

factoryname - a named factory to instantiate

Returns:

a GstDeviceProvider or null if unable to create device provider

listGetDeviceProviders

public static List<DeviceProviderFactory> listGetDeviceProviders(Rank minrank)

Get a list of factories with a rank greater or equal to minrank. The list of factories is returned by decreasing rank.

Parameters:

minrank - Minimum rank

Returns:

a GList of GstDeviceProviderFactory device providers. Use gst_plugin_feature_list_free() after usage.

get

public DeviceProvider get()

Returns the device provider of the type defined by the given device providerfactory.

Returns:

the GstDeviceProvider or null if the device provider couldn't be created

getDeviceProviderType

public Type getDeviceProviderType()

Get the GType for device providers managed by this factory. The type can only be retrieved if the device provider factory is loaded, which can be assured with gst_plugin_feature_load().

Returns:

the GType for device providers managed by this factory.

getMetadata

public String getMetadata(String key)

Get the metadata on this DeviceProviderFactory with key.

Parameters:

key - a key

Returns:

the metadata with key on this DeviceProviderFactory or null when there was no metadata with the given key.

getMetadataKeys

public String[] getMetadataKeys()

Get the available keys for the metadata on this DeviceProviderFactory.

Returns:

a null-terminated array of key strings, or null when there is no metadata. Free with g_strfreev() when no longer needed.

hasClasses

public boolean hasClasses(@Nullable
 @Nullable String classes)

Check if this DeviceProviderFactory matches all of the given classes

Parameters:

classes - a "/" separate list of classes to match, only match if all classes are matched

Returns:

true if this DeviceProviderFactory matches or if classes is null.

hasClassesv

public boolean hasClassesv(@Nullable
 @Nullable String[] classes)

Check if this DeviceProviderFactory matches all of the given classes

Parameters:

classes - a null terminated array of classes to match, only match if all classes are matched

Returns:

true if this DeviceProviderFactory matches.

builder

public static DeviceProviderFactory.Builder<? extends DeviceProviderFactory.Builder> builder()

A DeviceProviderFactory.Builder object constructs a DeviceProviderFactory with the specified properties. Use the various set...() methods to set properties, and finish construction with DeviceProviderFactory.Builder.build().
