ClassDescriptionThis common thread pool provides an abstraction to obtain a shared thread pool.This class provides methods to read and write matrix blocks from to HDFS using different data formats.This buffered output stream is essentially a merged version of BufferedOutputStream and DataOutputStream, wrt SystemDS requirements.This string tokenizer is essentially a simplified StringTokenizer.Custom input format and record reader to redirect common implementation of csv read over record readers (which are required for the parallel readers) to an input stream.This native long long - double hashmap is specifically designed for ctable operations which only require addvalue - extract semantics.This memory monitor periodically calls garbage collection in order to obtain the actual memory consumption during runtime.Class that can generate a stream of random numbers from standard normal distribution N(0,1).reference-counted file manager for SystemDS partition files.Class that can generate a stream of random numbers from Poisson distribution with specified mean.Stemmer, implementing the Porter Stemming Algorithm The Stemmer class transforms a word into its root form.Program converter functionalities for (1) creating deep copies of program blocks, instructions, function program blocks, and (2) serializing and parsing of programs, program blocks, functions program blocks.Utils for converting python data to java.Class that generates a pair of random numbers from standard normal distribution N(0,1).Utilities for sorting, primarily used for SparseRows.
