Class List<E>

java.lang.Object

java.util.AbstractCollection<E>

java.util.AbstractList<E>

java.util.AbstractSequentialList<@Nullable E>

org.gnome.glib.List<E>

Type Parameters:

E - The element type must be a MemorySegment, a String, a primitive value, or implement the Proxy interface. It is assumed that integers are stored in the pointer with GINT_TO_POINTER() and GPOINTER_TO_INT().

All Implemented Interfaces:

Iterable<E>, Collection<E>, List<E>, SequencedCollection<E>, Proxy

@NullMarked
public class List<E>
extends AbstractSequentialList<@Nullable E>
implements Proxy

Java wrapper for GLib.List that implements List.

Constructor Details

List

public List(@Nullable MemorySegment address,
 Function<@Nullable MemorySegment,E> make,
 @Nullable Consumer<@Nullable E> free,
 TransferOwnership ownership)

Create a new GLib.List wrapper.

Parameters:

address - the memory address of the head element of the List

make - a function to construct element instances

free - a function to free element instances. If ownership is "none" or "container", this can safely be set to null.

ownership - whether to free memory automatically

List

public List(Function<@Nullable MemorySegment,E> make,
 @Nullable Consumer<E> free,
 TransferOwnership ownership)

Create a wrapper for a new, empty GLib.List.

Parameters:

make - a function to construct element instances

free - a function to free element instances. If ownership is "none" or "container", this can safely be set to null.

ownership - whether to free memory automatically

List

public List(@Nullable MemorySegment address,
 Function<@Nullable MemorySegment,E> make,
 TransferOwnership ownership)

Create a new GLib.List wrapper.

Parameters:

address - the memory address of the head element of the List

make - a function to construct element instances

ownership - whether to free memory automatically

Method Details

setOwnership

public void setOwnership(TransferOwnership ownership)

Change ownership status of this list

Parameters:

ownership - the new ownership status

listIterator

public ListIterator<E> listIterator(int index)

Returns a list iterator over the elements in this GLib.List (in proper sequence).

Specified by:

listIterator in interface List<E>

Specified by:

listIterator in class AbstractSequentialList<@Nullable E>

Parameters:

index - index of first element to be returned from the list iterator (by a call to the next method)

Returns:

a list iterator over the elements in this list (in proper sequence).

size

public int size()

Retrieve the size of the list. This is an expensive operation for long lists, because the entire length must be traversed.

Specified by:

size in interface Collection<E>

Specified by:

size in interface List<E>

Specified by:

size in class AbstractCollection<E>

Returns:

the length of the list

isEmpty

public boolean isEmpty()

Checks if the list has no elements (the head of the list is null).

Specified by:

isEmpty in interface Collection<E>

Specified by:

isEmpty in interface List<E>

Overrides:

isEmpty in class AbstractCollection<E>

Returns:

whether the list is empty

handle

public MemorySegment handle()

Returns the memory address of the head of the list. This address can change if the list is modified.

Specified by:

handle in interface Proxy

Returns:

the memory address of the current GLib.List head, or MemorySegment.NULL if the head is null.

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout of one list node
