Constructor Details

MenuAttributeIter

public MenuAttributeIter(MemorySegment address)

Create a MenuAttributeIter proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

MenuAttributeIter

public MenuAttributeIter()

Creates a new MenuAttributeIter.

Method Details

getType

public static @Nullable Type getType()

Get the GType of the MenuAttributeIter class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected MenuAttributeIter 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.

Overrides:

asParent in class GObject

getName

public String getName()

Gets the name of the attribute at the current iterator position, as a string.

The iterator is not advanced.

Returns:

the name of the attribute

Since:

2.32

getNext

public boolean getNext(@Nullable Out<String> outName,
 @Nullable Out<Variant> value)

This function combines g_menu_attribute_iter_next() with g_menu_attribute_iter_get_name() and g_menu_attribute_iter_get_value().

First the iterator is advanced to the next (possibly first) attribute. If that fails, then false is returned and there are no other effects.

If successful, name and value are set to the name and value of the attribute that has just been advanced to. At this point, g_menu_attribute_iter_get_name() and g_menu_attribute_iter_get_value() will return the same values again.

The value returned in name remains valid for as long as the iterator remains at the current position. The value returned in value must be unreffed using g_variant_unref() when it is no longer in use.

Parameters:

outName - the type of the attribute

value - the attribute value

Returns:

true on success, or false if there is no additional attribute

Since:

2.32

getValue

public Variant getValue()

Gets the value of the attribute at the current iterator position.

The iterator is not advanced.

Returns:

the value of the current attribute

Since:

2.32

next

public boolean next()

Attempts to advance the iterator to the next (possibly first) attribute.

true is returned on success, or false if there are no more attributes.

You must call this function when you first acquire the iterator to advance it to the first attribute (and determine if the first attribute exists at all).

Returns:

true on success, or false when there are no more attributes

Since:

2.32
