PointerInterface

public class Preset
extends Interface

This interface offers methods to query and manipulate parameter preset sets.
A preset is a bunch of property settings, together with meta data and a name.
The name of a preset serves as key for subsequent method calls to manipulate
single presets.
All instances of one type will share the list of presets. The list is created
on demand, if presets are not used, the list is not created.

The interface comes with a default implementation that serves most plugins.
Wrapper plugins will override most methods to implement support for the
native preset format of those wrapped plugins.
One method that is useful to be overridden is gst_preset_get_property_names().
With that one can control which properties are saved and in which order.
When implementing support for read-only presets, one should set the vmethods
for gst_preset_save_preset() and gst_preset_delete_preset() to %NULL.
Applications can use gst_preset_is_editable() to check for that.

The default implementation supports presets located in a system directory,
application specific directory and in the users home directory. When getting
a list of presets individual presets are read and overlaid in 1) system,
2) application and 3) user order. Whenever an earlier entry is newer, the
later entries will be updated. Since 1.8 you can also provide extra paths
where to find presets through the GST_PRESET_PATH environment variable.
Presets found in those paths will be considered as "app presets".

Preset

public Preset(PointerContainer pointer)

Methodendetails

getClassHandler

public static ClassHandler getClassHandler()

deletePreset

public boolean deletePreset(@Nonnull
 Str name)

Delete the given preset.

Parameter:

name - preset name to remove

Gibt zurück:

%TRUE for success, %FALSE if e.g. there is no preset with that @name

deletePreset

public boolean deletePreset(String name)

Delete the given preset.

Parameter:

name - preset name to remove

Gibt zurück:

%TRUE for success, %FALSE if e.g. there is no preset with that @name

isEditable

public boolean isEditable()

Check if one can add new presets, change existing ones and remove presets.

Gibt zurück:

%TRUE if presets are editable or %FALSE if they are static

loadPreset

public boolean loadPreset(@Nonnull
 Str name)

Load the given preset.

Parameter:

name - preset name to load

Gibt zurück:

%TRUE for success, %FALSE if e.g. there is no preset with that @name

loadPreset

public boolean loadPreset(String name)

Load the given preset.

Parameter:

name - preset name to load

Gibt zurück:

%TRUE for success, %FALSE if e.g. there is no preset with that @name

renamePreset

public boolean renamePreset(@Nonnull
 Str old_name,
 @Nonnull
 Str new_name)

Renames a preset. If there is already a preset by the @new_name it will be
overwritten.

Parameter:

old_name - current preset name

new_name - new preset name

Gibt zurück:
