Module datarush.library
Package com.pervasive.datarush.sequences
Provides classes and interfaces related to sequences of tokens.
Sequences provide an efficient and convenient way for buffering tokens, compatible with
other DataRush objects.
DataRush provides both dense and sparse implementations of sequences. The primary implementations store data densely, allocating space for each entry. However, for sequences which will mainly consist of zero values, the sparse implementation may be more efficient.
