Constructor Details

ValueList

public ValueList(MemorySegment address)

Create a ValueList proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

Method Details

getType

public static @Nullable Type getType()

Get the GType of the ValueList class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected ValueList 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.

appendAndTakeValue

public static void appendAndTakeValue(Value value,
 Value appendValue)

Appends appendValue to the GstValueList in value.

Parameters:

value - a GValue of type GST_TYPE_LIST

appendValue - the value to append

Since:

1.2

appendValue

public static void appendValue(Value value,
 Value appendValue)

Appends appendValue to the GstValueList in value.

Parameters:

value - a GValue of type GST_TYPE_LIST

appendValue - the value to append

concat

public static void concat(Value dest,
 Value value1,
 Value value2)

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.

Parameters:

dest - an uninitialized GValue to take the result

value1 - a GValue

value2 - a GValue

getSize

public static int getSize(Value value)

Gets the number of values contained in value.

Parameters:

value - a GValue of type GST_TYPE_LIST

Returns:

the number of values

getValue

public static Value getValue(Value value,
 int index)

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

Parameters:

value - a GValue of type GST_TYPE_LIST

index - index of value to get from the list

Returns:

the value at the given index

init

public static Value init(Value value,
 int prealloc)

Initializes and pre-allocates a GValue of type GST_TYPE_LIST.

Parameters:

value - A zero-filled (uninitialized) GValue structure

prealloc - The number of entries to pre-allocate in the list

Returns:

The GValue structure that has been passed in

Since:

1.18

merge

public static void merge(Value dest,
 Value value1,
 Value value2)

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).

Parameters:

dest - an uninitialized GValue to take the result

value1 - a GValue

value2 - a GValue

prependValue

public static void prependValue(Value value,
 Value prependValue)

Prepends prependValue to the GstValueList in value.

Parameters:

value - a GValue of type GST_TYPE_LIST

prependValue - the value to prepend
