Examples of stallone.datasequence.DataSequenceLoader_SingleReaderImpl

stallone.datasequence.DataSequenceLoader_SingleReaderImpl

Single-Reader implementation of a DataSequenceLoader. This implementation only keeps a single reader to the source files and only keeps one file open at a time. It is geared towards saving memory and keeping the number of open files at 1, and will work fine as long as data is linearly traversed once through one of the iterators supplied. This implementation will be computationally inefficient if the data is accessed multiply times or via random access. This is because whenever a different file is accessed, its content is read and scanned, even if this has already been done in the past. Using this reader in a random access fashion thus creates much computational overhead. When random access is desired, a different implementation should be used. @author noe
