Detailed Description

An interface to the JavaScript backing of EME. This includes callbacks that are invoked by an EME implementation.

This type is thread-safe.

This MUST NOT be subclassed by the app. Only the public members are part of the public ABI. This allows us to add new members without breaking ABI compatibility.

Member Function Documentation

DataPathPrefix()

virtual std::string shaka::eme::ImplementationHelper::DataPathPrefix ( ) const

pure virtual

Gets the directory on the filesystem that should be used for data storage. This directory is specific for this EME implementation, so any files in it are for this implementation. ALL data MUST be in this directory.

Implemented in shaka::js::eme::ImplementationHelperImpl.

OnKeyStatusChange()

virtual void shaka::eme::ImplementationHelper::OnKeyStatusChange ( const std::string &  session_id ) const

pure virtual

An event callback that should be called when the key status changes. This schedules a JavaScript event, but doesn't dispatch it.

Parameters

session_id

The ID of the session whose key statuses changed.

Implemented in shaka::js::eme::ImplementationHelperImpl.

OnMessage()

virtual void shaka::eme::ImplementationHelper::OnMessage ( const std::string &  session_id, MediaKeyMessageType  message_type, const uint8_t *  data, size_t  data_size  ) const

pure virtual

An event callback that should be called when a message should be sent to the JavaScript application. This only schedules a JavaScript event, it does not dispatch it.

Parameters

session_id	The ID of the session that will receive the message.
message_type	The type of the message.
data	The data contents of the message.
data_size	The number of bytes in |data|.

Implemented in shaka::js::eme::ImplementationHelperImpl.
