public class TypeModule
extends PropertyHolder

`GTypeModule` provides a simple implementation of the `GTypePlugin`
interface.

The model of `GTypeModule` is a dynamically loaded module which
implements some number of types and interface implementations.

When the module is loaded, it registers its types and interfaces
using [method@GObject.TypeModule.register_type] and
[method@GObject.TypeModule.add_interface].
As long as any instances of these types and interface implementations
are in use, the module is kept loaded. When the types and interfaces
are gone, the module may be unloaded. If the types and interfaces
become used again, the module will be reloaded. Note that the last
reference cannot be released from within the module code, since that
would lead to the caller's code being unloaded before `g_object_unref()`
returns to it.

Keeping track of whether the module should be loaded or not is done by
using a use count - it starts at zero, and whenever it is greater than
zero, the module is loaded. The use count is maintained internally by
the type system, but also can be explicitly controlled by
[method@GObject.TypeModule.use] and [method@GObject.TypeModule.unuse].
Typically, when loading a module for the first type, `g_type_module_use()`
will be used to load it so that it can initialize its types. At some later
point, when the module no longer needs to be loaded except for the type
implementations it contains, `g_type_module_unuse()` is called.

`GTypeModule` does not actually provide any implementation of module
loading and unloading. To create a particular module type you must
derive from `GTypeModule` and implement the load and unload functions
in `GTypeModuleClass`.

TypeModule

public TypeModule(PointerContainer pointer)

Methodendetails

getClassHandler

public static ClassHandler getClassHandler()

addInterface

public void addInterface(long instance_type,
 long interface_type,
 @Nonnull
 InterfaceInfo interface_info)

Registers an additional interface for a type, whose interface lives
in the given type plugin. If the interface was already registered
for the type in this plugin, nothing will be done.

As long as any instances of the type exist, the type plugin will
not be unloaded.

Since 2.56 if @module is %NULL this will call g_type_add_interface_static()
instead. This can be used when making a static build of the module.

Parameter:

instance_type - type to which to add the interface.

interface_type - interface type to add

interface_info - type information structure

registerEnum

public long registerEnum(@Nonnull
 Str name,
 @Nonnull
 EnumValue const_static_values)

Looks up or registers an enumeration that is implemented with a particular
type plugin. If a type with name @type_name was previously registered,
the #GType identifier for the type is returned, otherwise the type
is newly registered, and the resulting #GType identifier returned.

As long as any instances of the type exist, the type plugin will
not be unloaded.

Since 2.56 if @module is %NULL this will call g_type_register_static()
instead. This can be used when making a static build of the module.

Parameter:

name - name for the type

const_static_values - an array of #GEnumValue structs for the possible enumeration values. The array is terminated by a struct with all members being 0.

Gibt zurück:

the new or existing type ID

registerEnum

public long registerEnum(String name,
 @Nonnull
 EnumValue const_static_values)

Looks up or registers an enumeration that is implemented with a particular
type plugin. If a type with name @type_name was previously registered,
the #GType identifier for the type is returned, otherwise the type
is newly registered, and the resulting #GType identifier returned.

As long as any instances of the type exist, the type plugin will
not be unloaded.

Since 2.56 if @module is %NULL this will call g_type_register_static()
instead. This can be used when making a static build of the module.

Parameter:

name - name for the type

const_static_values - an array of #GEnumValue structs for the possible enumeration values. The array is terminated by a struct with all members being 0.

Gibt zurück:

the new or existing type ID

registerFlags

public long registerFlags(@Nonnull
 Str name,
 @Nonnull
 FlagsValue const_static_values)

Looks up or registers a flags type that is implemented with a particular
type plugin. If a type with name @type_name was previously registered,
the #GType identifier for the type is returned, otherwise the type
is newly registered, and the resulting #GType identifier returned.

As long as any instances of the type exist, the type plugin will
not be unloaded.

Since 2.56 if @module is %NULL this will call g_type_register_static()
instead. This can be used when making a static build of the module.

Parameter:

name - name for the type

const_static_values - an array of #GFlagsValue structs for the possible flags values. The array is terminated by a struct with all members being 0.

Gibt zurück:

the new or existing type ID

registerFlags

public long registerFlags(String name,
 @Nonnull
 FlagsValue const_static_values)

Looks up or registers a flags type that is implemented with a particular
type plugin. If a type with name @type_name was previously registered,
the #GType identifier for the type is returned, otherwise the type
is newly registered, and the resulting #GType identifier returned.

As long as any instances of the type exist, the type plugin will
not be unloaded.

Since 2.56 if @module is %NULL this will call g_type_register_static()
instead. This can be used when making a static build of the module.

Parameter:

name - name for the type

const_static_values - an array of #GFlagsValue structs for the possible flags values. The array is terminated by a struct with all members being 0.

Gibt zurück:

the new or existing type ID

registerType

public long registerType(long parent_type,
 @Nonnull
 Str type_name,
 @Nonnull
 TypeInfo type_info,
 int flags)

Looks up or registers a type that is implemented with a particular
type plugin. If a type with name @type_name was previously registered,
the #GType identifier for the type is returned, otherwise the type
is newly registered, and the resulting #GType identifier returned.

When reregistering a type (typically because a module is unloaded
then reloaded, and reinitialized), @module and @parent_type must
be the same as they were previously.

As long as any instances of the type exist, the type plugin will
not be unloaded.

Since 2.56 if @module is %NULL this will call g_type_register_static()
instead. This can be used when making a static build of the module.

Parameter:

parent_type - the type for the parent class

type_name - name for the type

type_info - type information structure

flags - flags field providing details about the type

Gibt zurück:

the new or existing type ID

registerType

public long registerType(long parent_type,
 String type_name,
 @Nonnull
 TypeInfo type_info,
 int flags)

Looks up or registers a type that is implemented with a particular
type plugin. If a type with name @type_name was previously registered,
the #GType identifier for the type is returned, otherwise the type
is newly registered, and the resulting #GType identifier returned.

When reregistering a type (typically because a module is unloaded
then reloaded, and reinitialized), @module and @parent_type must
be the same as they were previously.

As long as any instances of the type exist, the type plugin will
not be unloaded.

Since 2.56 if @module is %NULL this will call g_type_register_static()
instead. This can be used when making a static build of the module.

Parameter:

parent_type - the type for the parent class

type_name - name for the type

type_info - type information structure

flags - flags field providing details about the type

Gibt zurück:

the new or existing type ID

Parameter:

name - a human-readable name to use in error messages.

setName

public void setName(String name)

Sets the name for a #GTypeModule

Parameter:

name - a human-readable name to use in error messages.

unuse

public void unuse()

Decreases the use count of a #GTypeModule by one. If the
result is zero, the module will be unloaded. (However, the
#GTypeModule will not be freed, and types associated with the
#GTypeModule are not unregistered. Once a #GTypeModule is
initialized, it must exist forever.)

use

public boolean use()

Increases the use count of a #GTypeModule by one. If the
use count was zero before, the plugin will be loaded.
If loading the plugin fails, the use count is reset to
its prior value.

Gibt zurück:

%FALSE if the plugin needed to be loaded and loading the plugin failed.

Implements interface TypePlugin. Call this to get access to interface functions.
