Usage

Technical Details: For capacity management, SDMCache uses an LRU (least recently used) like algorithm that ensures that the most recently used entries are not removed first because of reaching the maximum capacity. SDMCache currently supports only the tokenized prefix search as stated above. As a future improvement SDMCache is also going to support custom search logic. SDMCache is an implementer of the android.os.Parcelable interface provided by Android SDK. SDMCache depends on SAPData specific interfaces of SDMParser but does not depend on the real implementation of SDMParser.
