Detailed Description

class com::wombat::mamda::MamdaMultiParticipantManager;

MamdaMultiParticipantManager is a class that manages updates on a consolidated basis for securities that may be traded on multiple exchanges and which may have a national best bid and offer. Developers are notified of each element available for the consolidated security, including the national best bid and offer, and each regional exchange (Market Maker). Developers can pick and choose which elements they wish to provide handling for (e.g., BBO-only, certain regional exchanges, etc.).

Specialized Listeners can be added to the [MamdaMultiParticipantManager](classcom_1_1wombat_1_1mamda_1_1MamdaMultiParticipantManager.html) in response to the callbacks on the [MamdaMultiParticipantHandler](interfacecom_1_1wombat_1_1mamda_1_1MamdaMultiParticipantHandler.html) being invoked. Alternatively, the Listeners can be added up front if the participants are known in advance.

Note: the [MamdaMultiParticipantManager](classcom_1_1wombat_1_1mamda_1_1MamdaMultiParticipantManager.html) can also be used for securities that are not traded on multiple exchanges.
