Class Details

class Gst.ValueList

Abstract:No

classmethod append_and_take_value(value, append_value)

Parameters:

• value (GObject.Value) – a GObject.Value of type #GST_TYPE_LIST
• append_value (GObject.Value) – the value to append

Appends append_value to the Gst.ValueList in value.

New in version 1.2.

classmethod append_value(value, append_value)

Parameters:

• value (GObject.Value) – a GObject.Value of type #GST_TYPE_LIST
• append_value (GObject.Value) – the value to append

Appends append_value to the Gst.ValueList in value.

classmethod concat(value1, value2)

Parameters:

• value1 (GObject.Value) – a GObject.Value
• value2 (GObject.Value) – a GObject.Value

Returns:

an uninitialized GObject.Value to take the result

Return type:

dest: GObject.Value

Concatenates copies of value1 and value2 into a list. Values that are not of type #GST_TYPE_LIST are treated as if they were lists of length 1. dest will be initialized to the type #GST_TYPE_LIST.

classmethod get_size(value)

Parameters:value (GObject.Value) – a GObject.Value of type #GST_TYPE_LIST Returns:the number of values Return type:int

Gets the number of values contained in value.

classmethod get_value(value, index)

Parameters:

• value (GObject.Value) – a GObject.Value of type #GST_TYPE_LIST
• index (int) – index of value to get from the list

Returns:

the value at the given index

Return type:

GObject.Value

Gets the value that is a member of the list contained in value and has the index index.

classmethod merge(value1, value2)

Parameters:

• value1 (GObject.Value) – a GObject.Value
• value2 (GObject.Value) – a GObject.Value

Returns:

an uninitialized GObject.Value to take the result

Return type:

dest: GObject.Value

Merges copies of value1 and value2. Values that are not of type #GST_TYPE_LIST are treated as if they were lists of length 1.

The result will be put into dest and will either be a list that will not contain any duplicates, or a non-list type (if value1 and value2 were equal).

classmethod prepend_value(value, prepend_value)

Parameters:

• value (GObject.Value) – a GObject.Value of type #GST_TYPE_LIST
• prepend_value (GObject.Value) – the value to prepend

Prepends prepend_value to the Gst.ValueList in value.
