Package com.refinitiv.eta.valueadd.cache Description

This package contains the ETA Value Add Cache. The Value Add Payload Cache component provides a facility for storing OMM containers (the data payload of OMM messages). Typical use of a payload cache is to store the current image of OMM data streams, where each entry in the cache corresponds to a single data stream. The initial content of a cache entry is defined by the payload of a refresh message. The current (or last) value of the entry is defined by the cumulative application of all refresh and update messages applied to the cache entry container. Values are stored in and retrieved from the cache as encoded OMM containers.
