Detailed Description

Persistent Object Interface. [plug imp]
This interface is used to store/restore attributes of an object. An IPlugController can implement this interface to handle presets. The gui-xml for a preset control looks like this:

....
<view name="PresetView" data="Preset"/>
....
<template name="PresetView">
        <view name="preset control" size="0, 0, 100, 20"/>
        <switch name="store preset" size="125,0,80,20" style="push|immediate" title="Store"  />
        <switch name="remove preset" size="220,0,80,20" style="push|immediate" title="Delete"  />
</template>

The tag data="Preset" tells the host to create a preset controller that handles the 3 values named "preset control", "store preset", and "remove preset".

Member Function Documentation

getClassID()

virtual tresult PLUGIN_API Steinberg::IPersistent::getClassID ( char8 * uid )

pure virtual

The class ID must be a 16 bytes unique id that is used to create the object. This ID is also used to identify the preset list when used with presets.

loadAttributes()

virtual tresult PLUGIN_API Steinberg::IPersistent::loadAttributes ( IAttributes * )

pure virtual

Restore all members/data from the passed IAttributes.

saveAttributes()

virtual tresult PLUGIN_API Steinberg::IPersistent::saveAttributes ( IAttributes * )

pure virtual

Store all members/data in the passed IAttributes.
