Constructor Details

DeviceProviderClass

public DeviceProviderClass(MemorySegment address)

Create a DeviceProviderClass proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

readFactory

public DeviceProviderFactory readFactory()

Read the value of the field factory.

Returns:

The value of the field factory

writeFactory

public void writeFactory(DeviceProviderFactory factory)

Write a value in the field factory.

Parameters:

factory - The new value for the field factory

overrideProbe

public void overrideProbe(Arena arena,
 @Nullable Method method)

Override virtual method probe.

Parameters:

method - the method to invoke

overrideStart

public void overrideStart(Arena arena,
 @Nullable Method method)

Override virtual method start.

Parameters:

method - the method to invoke

overrideStop

public void overrideStop(Arena arena,
 @Nullable Method method)

Override virtual method stop.

Parameters:

method - the method to invoke

readMetadata

public MemorySegment readMetadata()

Read the value of the field metadata.

Returns:

The value of the field metadata

writeMetadata

public void writeMetadata(MemorySegment metadata)

Write a value in the field metadata.

Parameters:

metadata - The new value for the field metadata

addMetadata

public void addMetadata(String key,
 String value)

Set key with value as metadata in klass.

Parameters:

key - the key to set

value - the value to set

Since:

1.4

addStaticMetadata

public void addStaticMetadata(String key,
 String value)

Set key with value as metadata in klass.

Same as gst_device_provider_class_add_metadata(), but value must be a static string or an inlined string, as it will not be copied. (GStreamer plugins will be made resident once loaded, so this function can be used even from dynamically loaded plugins.)

Parameters:

key - the key to set

value - the value to set

Since:

1.4

getMetadata

public @Nullable String getMetadata(String key)

Get metadata with key in klass.

Parameters:

key - the key to get

Returns:

the metadata for key.

Since:

1.4

setMetadata

public void setMetadata(String longname,
 String classification,
 String description,
 String author)

Sets the detailed information for a GstDeviceProviderClass.

This function is for use in _class_init functions only.

Parameters:

longname - The long English name of the device provider. E.g. "File Sink"

classification - String describing the type of device provider, as an unordered list separated with slashes ('/'). See draft-klass.txt of the design docs for more details and common types. E.g: "Sink/File"

description - Sentence describing the purpose of the device provider. E.g: "Write stream to a file"

author - Name and contact details of the author(s). Use \\n to separate multiple author metadata. E.g: "Joe Bloggs <joe.blogs at foo.com>"

Since:

1.4

setStaticMetadata

public void setStaticMetadata(String longname,
 String classification,
 String description,
 String author)

Sets the detailed information for a GstDeviceProviderClass.

This function is for use in _class_init functions only.

Same as gst_device_provider_class_set_metadata(), but longname, classification, description, and author must be static strings or inlined strings, as they will not be copied. (GStreamer plugins will be made resident once loaded, so this function can be used even from dynamically loaded plugins.)

Parameters:

longname - The long English name of the element. E.g. "File Sink"

classification - String describing the type of element, as an unordered list separated with slashes ('/'). See draft-klass.txt of the design docs for more details and common types. E.g: "Sink/File"

description - Sentence describing the purpose of the element. E.g: "Write stream to a file"

author - Name and contact details of the author(s). Use \\n to separate multiple author metadata. E.g: "Joe Bloggs <joe.blogs at foo.com>"
