Sets our main struct and passes it to the parent class.

Members

Functions

addMetadata

void addMetadata(string key, string value)

Set @key with @value as metadata in @klass.

addPadTemplate

void addPadTemplate(PadTemplate templ)

Adds a padtemplate to an element class. This is mainly used in the _class_init functions of classes. If a pad template with the same name as an already existing one is added the old one is replaced by the new one.

addStaticMetadata

void addStaticMetadata(string key, string value)

Set @key with @value as metadata in @klass.

addStaticPadTemplate

void addStaticPadTemplate(StaticPadTemplate staticTempl)

Adds a pad template to an element class based on the static pad template @templ. This is mainly used in the _class_init functions of element implementations. If a pad template with the same name already exists, the old one is replaced by the new one.

getElementClassStruct

GstElementClass* getElementClassStruct()

Get the main Gtk struct

getMetadata

string getMetadata(string key)

Get metadata with @key in @klass.

getPadTemplate

PadTemplate getPadTemplate(string name)

Retrieves a padtemplate from @element_class with the given name. <note>If you use this function in the #GInstanceInitFunc of an object class that has subclasses, make sure to pass the g_class parameter of the #GInstanceInitFunc here.</note>

getPadTemplateList

ListG getPadTemplateList()

Retrieves a list of the pad templates associated with @element_class. The list must not be modified by the calling code. <note>If you use this function in the #GInstanceInitFunc of an object class that has subclasses, make sure to pass the g_class parameter of the #GInstanceInitFunc here.</note>

getStruct

void* getStruct()

the main Gtk struct as a void*

setMetadata

void setMetadata(string longname, string classification, string description, string author)

Sets the detailed information for a #GstElementClass. <note>This function is for use in _class_init functions only.</note>

setStaticMetadata

void setStaticMetadata(string longname, string classification, string description, string author)

Sets the detailed information for a #GstElementClass. <note>This function is for use in _class_init functions only.</note>

Variables
