Examples of com.opengamma.provider.livedata.LiveDataMetaDataProvider

com.opengamma.provider.livedata.LiveDataMetaDataProvider
A provider of live data meta-data.
This provides access to a data source for live data. For example, major data sources provide ticking equity prices.
Since live data is best expressed via JMS, this provider only provides a basic description of how to access the underlying data source.
This interface is read-only. Implementations must be thread-safe.
