Class MPlayerApplicationSettingsObserver

class MPlayerApplicationSettingsObserver;

Description

This class is for supporting the player application settings PDUs in AVRCP1.3 specification section 5.2. The RegisterNotification PDU for EVENT_PLAYER_APPLICATION_SETTING_CHANGED is also supported through this API.

The media player should first define all the attributes it supports, using DefineAttributeL. When an attribute's value is changed by the media player, it should call SetAttributeL to inform the controller. When the controller changes a setting, the media player application receives a callback via the MPlayerApplicationSettingsNotify interface

IMPORT_C void DefineAttributeL(TUint aAttributeID, TDesC8 &aAttributeText, RArray< TUint > &aValues, RArray< TPtrC8 > &aValueTexts, TUint aInitialValue);

Description

Define an attribute supported by this player. It will be included in future responses to the following PDUs: ListPlayerApplicationSettingAttributes, ListPlayerApplicationSettingValues, GetCurrentPlayerApplicationSettingValue, GetPlayerApplicationSettingAttributeText, GetPlayerApplicationSettingValueText,

Parameters

TUint aAttributeID The specification or player defined attribute TDesC8 &aAttributeText The UTF8 text name of the attribute(allowed text length is 1-255) - the API will take a copy RArray< TUint > &aValues The list of defined values RArray< TPtrC8 > &aValueTexts The UTF8 text for each defined value(allowed text length is 1-255) - The API will make copies. TUint aInitialValue The initial value for this attribute

Leave codes

KErrNoMemory if memory could not be allocated to store the copies of aAttributeID and relative settings KErrNotSupported if attribute or value is out of specification defined range, or aValueTexts is not equal length to aValues

IMPORT_C void SetAttributeL(TUint aAttributeID, TUint aValue);

Description

Set the current value of a previously defined attribute This updates the cache and will cause completion of a pending EVENT_PLAYER_APPLICATION_SETTING_CHANGED notification PDU

Parameters

TUint aAttributeID The specification or player defined attribute TUint aValue The current value

Leave codes

KErrNotFound if the attribute is not defined, KErrArgument if the value is not valid according to the definition
